Cloud Computing for Education and Learning
Cloud Computing for Education and Learning:Education and Learning as a Service (ELaaS)Mohssen M. AlabbadiComputer Research Institute (CRI) King Abdulaziz City for Science & Technology (KACST)Riyadh, Saudi Arabia Alabbadi@.saAbstract —Cloud computing, d espite its hype, is being wid ely d eployed , with its d ynamic scalability and usage of virtualized resources, in many organizations for several applications. It is envisioned that, in the near future, cloud computing will have a significant impact on the educational and learning environment, enabling their own users (i.e., learners, instructors, an dadministrators) to perform their tasks effectively with less cost by utilizing the available cloud -based applications offered by the cloud service provid ers. This paper d iscusses the use of cloud computing in the ed ucational and learning arena, to be called ‟Education and Learning as a Service” (ELaaS), emphasizing its possible benefits and offerings. It is essential for an ed ucational and learning organization, with its bud get restrictions and sustainability challenges, to use the cloud formation best suited for a particular IT activity. The Jericho Forum proposes a cloud computing formation mod el, called the Cloud Cube Mod el (CCM), which is based on 4 criteria. To preserve the symmetry ofthe cube,a new cloud computing formation mod el, called the Complete Cloud Computing Formations (C 3F), is proposed.The IT activities in the ed ucational and learning organizations are then classified with respect to the two criteria: mission criticality and sensitivity. Each class is then mapped into the appropriate position in the C 3F, creating ELaaS Quad rant.This essentially establishes a general conceptual framework for ELaaS.Keywords-Cloud Comp uting;Cloud Comp uting Formations;Education and Learning as a Service (ELaaS);Grid Comp uting;Information and Communication Technologies (ICT) in Education;Virtualization; Web Services; Utility ComputingI. I NTRODUCTIONCloud computing is an emerging Internet-based computing paradigm, with its built-in elasticity and scalability,for delivering on-demand information technology (IT)services tousers in a pay-per-use basis, in similar fashion as already donefor other utilities (i.e., water, electricity, etc.).It is a confluenceof business developments and the following existing ITtechnologies:x Virtualization:It enables the creation of a virtual (as opposed to actual) version of an IT resource (e.g., an operating system, a server, a storage device, or network).This allows data center consolidation and provides separation and protection;x Grid Computing:It enables the execution of tasks over multiple computers dispersed over geographicalareas, forming a seemingly supercomputer capability;xUtility Computing: It refers to the packaging and provisioning of computing resources in the form of metered service with some pricing scheme, thus with virtualization, IT resources can be provisioned as an on-demand service available on a subscription basis 1[14];xWeb Services: Web services, in particular those based on the Simple Object Access Protocol (SOAP) which is an XML-based open source message transport protocol, allows software delivery, where pieces of the software can be developed and then published on a registry to be dynamically discovered and consumed by other client applications over different transport protocols (e.g., HTTP, TCP/IP, etc.) irrespective of the programming language and platform. Web services have created the foundation for the Service Oriented Architecture (SOA) paradigm and, most importantly, SOAP-based Web services are now being used in the delivery of some aspects of cloud computing which not only deliver software remotely but also other IT-related functionality [20].Three trends have contributed to the emergence of cloud computing: the Internet and its technologies, in particular, World Wide Web (WWW) and Web 2.0 functionality;the catch up of telecommunications with hardware and software,where open standards were leveraged,resulting in low cost of broadband and wide availability of accessible high-speed wireless networks; and the falling cost of storage andcomputing devices,first led by mainframes and minicomputersthen PCs, and, more recently, by Internet-enabled handheld mobile devices.All these technologies and trends made computing more distinctively distributed, thus migrating back to huge data works of these computing plants, called “IT factories” [1], with c mmercial realizati n, f rm “cl ud computing” [7]. Cloud computing provides users a power ofchoice among less expensive (or free) competing services thatare user-friendly, accessible from any location, and more reliable [1].It marks the reversal of a long-standing trend, where end users and organizations are now willing to surrender1 The provision of software programs and applications to users as a service viathe Internet by application service providers (ASPs) during the 1990s could not succeed because of insufficient bandwidth [20] and importability due to the use of proprietary technologies.a large measure of control to 3rd-party service providers [8] to gain several advantages such as redirecting resources, focusing on long-term strategic business development, and business continuity [15].When compared to the existed traditional IT services provisioning models, cloud computing has many advantages such as reduced upfront investment (i.e.,software,hardware, and professional staff to maintain servers and upgrade software[15]),reduced launching time, where days become hours [15],expected performance, high availability, infinite scalability, tremendous fault-tolerance capability[22], and enhanced collaboration,accessibility, and mobility, allowing users to use any device, such as a personal computer (PC), or a mobile phone, etc. [8].Therefore, the use of cloud computing will have a profound positive impact on the cost structure of all the industries using IT resources by lowering the total cost of ownership (TCO)[8], resulting in an indirect crucial impact on business creation and the macroeconomic performance at national levels [6], extending to a global level.This benefits the private as well as the public sectors,including healthcare, education (especially for e-learning)[5], and the activities of government agencies.In both academia and industry, cloud computing has been recently attracting significant momentum and attention as one of those opportunities that could prove to be of immense benefits and empowering in some situations, due to its flexibility and pay-per-use cost structure, for organizations. In the educational and learning arena, this will be called ‟Education and Learning as a Service” (ELaaS).Cloud computing was in the list of the top 10 strategic technologies and trends identified by Gartner, the US analyst firm,consecutively in the previous years. In 2008, it was listed as ‟Web Platform & Web Oriented Architecture (WOA)” due to the success of Software as a Service (SaaS) model and it then became pronounced as ‟cloud computing”in the years 2009 through 20112.The Horizon reports, resulted from collaboration between the New Media Consortium (NMC) and DUCAUS Learning Initiative (E LI), a program of the influential EDUCAUSE,a non-for-profit US organization,aim to provide an educational-orientated perspective on expected key emerging technologies for higher education as well as K-12 education published as separate reports by identifying the emerging technologies likely to have a large impact on teaching, learning, research, or creative expression within learning-focused organizations. The higher education and K-12 editions do not differ in terms of the technologies featured but in terms of the adoption Horizons because K-12 education lags behind higher education in using IT technologies.Cloud computing was placed as a unifying technology supporting other emerging technologies in the year 2008 [11].Then it 2See Gartner, Inc., Press Releases, Gartner Newsroom, Retrieved online, on Aug. 30, 2011, at /it/page.jsp?id=530109 (for the year 2008),/it/page.jsp?id=777212 (for the year 2009), /it/page.jsp?id=1210613 (for the year 2010), and finally /it/page.jsp?id=1454221, (for the year 2011). appeared as an emerging technology to be adopted in 1-2 years for 2009 [11]and 2010 [12] but it gained the power of a key trend in 2011 [13]. IDC, a US market research firm, estimated the IT spending on cloud computing services to reach US$42 billion by 2012 [15].There are several successful deployments of cloud computing within educational and learning organizations, utilizing both commercial and non-commercial cloud computing solutions [9,14,18,19,21]. However, there are several “clo ud fo rmatio ns” (i.e., forms of cloud computing) and it is essential for an educational and learning organization, with its budget restrictions and sustainability challenges, to use the cloud formations best suited to its IT activities. The Jericho3Forum [10]has established a cloud computing formation model, called the Cloud Cube Model (CCM) which is based on 4 criteria (i.e., dimensions) [10].The use of a cube, a3-dimensional object, to represent the 4 criteria eliminates the symmetry inherited in the cube. Thus a new cloud computing formation model, called the Complete Cloud Computing Formations Model (C3F), is proposed. The IT activities in the educational and learning organizations are then classified with respect to the two criteria: mission criticality and sensitivity.E ach class of the IT activities is then mapped into the appropriate position in the C3F, thus creating E LaaS. This essentially establishes a general conceptual framework for adopting and deploying ELaaS.The structure of the rest of the paper is as follows. Section II properly defines cloud computing. C3F is explained in details in Section III. The classification of the IT activities in educational and learning organizations is discussed in Section IV. Section V shows the mapping of these IT activities into C3F, creating ELaaS. Finally, the concluding remarks are given in Section VI.II.C LOUD COMPUTINGCloud computing is a nascent business and highly disruptive technology concept with different meanings for different IT professionals. For application and IT users, it is IT as a service (ITaaS),delivering computing, storage, and applications over the Internet from centralized data centers, and for Internet application developers, it is an Internet-scale software development platform and runtime environment, whereas for infrastructure providers and administrators, it is massive, distributed data center infrastructure connected by IP networks [15]. These different views are clearly reflected in the views of cloud computing for some providers such as Amazon, Microsoft,and Google [2]. Furthermore, the abstracted definition of cloud computing [19] does not distinguish it from other paradigms such as grid computing; this abstracted view can be used for comparing cloud computing with other 3Jericho (called Ārīḥā, in Arabic, meaning ‟fragrant,” driven from the word Reah and called yəriḥo in Hebrew) is a city located near the Jordan River in the West Bank of the Palestinian territories. It is situated well below sea level north of the Dead Sea, thus it is the lowest permanently inhabited site on earth. It is also believed to be the oldest continuously inhabited city in the world (Wikipedia, Jericho, May 21, 2011, Wikimedia Foundation, Inc., San Francisco, CA, USA, Retrieved, online. on Aug 30, 2011, at /wiki/Jericho).computing paradigms as done in [17] when cloud computing was compared, based on computer architecture model, with service computing and pervasive computing.The disparity of cloud computing definition is even extended to organizations such as E DUCAUSE,which views c lo ud co mputing as “the delivery of scalable IT resources over the Internet, as opposed to hosting and operating those resources locally, such as on a college or university network” [4]; this definition clearly lacks the service concept and pay-per-use aspect of cloud computing.Unfortunately, there is abundance of definitions for“cloud computing” in the literature, with hype and divergent viewpoints, leading to a non-standard definition;the Joint Information Systems Committee(JISC)confirm the confusion about the terms “cloud”and “cloud computing”[1].In this paper, t he “U.S” National Institute of Standards and Technology (NIST)definition is adopted. NIST defines cloud computing as a‟model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.This cloud model promotes availability and is composed of five essential characteristics,three service models, and four deployment models” [16].The five essential characteristics are [16]:on-demand self-service, where a consumer can unilaterally provision computing capabilities as needed automatically without requiring human interaction from each service's provider; broad network access, where the capabilities are available over the network and accessed through standard mechanisms, promoting the use of heterogeneous thick or thin client platforms such as mobile phones, laptops, and PDAs;resource pooling, where the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumers demands;rapid elasticity,where the capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out, and rapidly released to quickly scale in; and measured service, where the cloud service providers automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service.There are three service models of cloud computing, where in all models the consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or applications. The three service models are Infrastructure as a Service(IaaS), Platform as a Service (PaaS),and Software as a Service (SaaS) [16].With IaaS, the consumer,based on demands, can provision processing, storage, networks, and other computing resources, such that the consumer is able to deploy,run, and control arbitrary software, including operating systems and applications,with possibly limited control of select networking components (e.g., host firewalls)[16]. By virtualization, hardware level resources are abstracted and encapsulated, providing a flexible infrastructure of distributed data center services, where the end user can access the services through a standardized interface, connected via Internet-style networking. Examples of IaaS are Amazon EC2and S3.With PaaS, the consumer can deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the cloud provider, such that the consumer has control over the deployed applications and possibly application hosting environment configurations [16]. It is the middleware providing application services and/or runtime environment for cloud applications, layering between IaaS and SaaS. It includes operating system support and software development frameworks to provide a platform for developers to develop, test, and deploy Web-scale applications and services.Google APP Engine and Microsoft Azure are examples of PaaS.On the other hand, with SaaS, t he pro vider’s software applications are accessible by the consumer from various client devices through a thin client interface such as a web browser, where the consumer may possibly have control over limited user-specific application configuration settings. SaaS is simply top-layer applications delivered on demand.SaaS is the most visible layer of cloud computing for end users. A well known example for SaaS offerings is .There are four deployment models for cloud computing: private cloud, community cloud, public cloud, and hybrid cloud [16]. When the cloud infrastructure is owned solely for an organization, providing hosted services to a limited numberof people behind a firewall, it is called a private cloud; it also called an internal cloud or a corporate cloud. But when the cloud infrastructure is shared by several organizations, supporting a specific community that has shared concerns (e.g., security requirements or compliance considerations), then it is called community cloud.Both the private and community clouds may be managed by the organizations or a 3rd-party and may exist on premise or off premise.On the other hand, public cloud makes its cloud infrastructure available to the general public or a large group and is owned by the organization selling the cloud services; it is also called external cloud. Hybrid cloud is a composition of two or more cloud models (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology, enabling data and application portability.Cloud computing faces five major challenges that need to be addressed: security, interoperability, availability, performance, and data migration. Security is concerned about data privacy, confidentiality, and network traffic isolation through partitioning,whereas interoperability must support customer choice and additional agility (for example, in workload mobility). Service level agreement (SLA) should address performance, availability, latency, and QoS (quality-of-service) issues. On the other hand, the problem of migrating data between clouds,both public and private,is probably the biggest challenge [15].III.C OMPLETE C LOUD C OMPUTING F ORMATIONS (C3F)There are several “clo ud fo rmatio ns” (i.e., forms of cloud computing), where each form offers different characteristics with varying degrees of flexibility, collaborative opportunities, and risks [10]. The Jericho Forum [10]proposes a cloudcomputing formation model, called the Cloud Cube Model (CCM),shown in Fig.1.The CCM is based on 4 criteria (i.e., dimensions) to differentiate cloud formations from each other and the manner of their provision. The CCM uses 4 faces of the cube, as shown in Fig. 1, with two faces left blanks, representing no criterion (i.e., empty faces). This eliminates the symmetry of the cube and it may introduce confusion, when categorizing the cloud services as done in [3].Figure 1. The Cloud Cube Model (CCM)from the Jericho Forum[10]To preserve the use of a cube with its symmetry, where every pair of opposite faces represents the same criterion, the number of criteria needs to be reduced to three. The reduction is simply done by combing two criteria of the original CCM into one, resulting in a new cloud computing model, to be called the Complete Cloud Computing Formation (C 3F). As in CCM, other attributes like ‟offshore ” and ‟onshore ,” e ven though they are relevant, are not considered. The C 3F is depicted in Fig. 2 and its three dimensions are as explained in details below.I. Physical Location and Management: This deals with the physical location of the cloud infrastructure with respect to the o rganizatio n’s bo undaries and who is managing the delivery of the cloud service(s) used by the organization.The management is primarily a policy issue (i.e. a business decision, not a technical or architectural decision) which must be embodied in a contract with the cloud provider.Thus, the following types result:x Internal/In-source d(Int/In): It is within the organization's physical boundary (i.e., Internal) under the control of the organization's own staff (In-sourced).x Internal/Outsourced (Int/Out):It is within the organization's physical boundary (i.e., Internal) under the control of a 3rd -party (Outsourced).x External/Outsourced (Ext/Out): It is not within organization's physical boundary (E xternal) under the control of a 3rd -party (Outsourced). Most likely, the owner of the cloud infrastructure is controlling it as well, as in the case of public cloud.The case for External/In-sourced form is not practical with the present technology. This is like a public cloud provider giving control of its infrastructure and services to its customers.II. Ownership: It defines the ownership of the cloudtechnology, services, interfaces, etc. It indicates the degree of interoperability to enable “data/application transpo rtability” between the organization's systems and other cloud forms, and the ability to withdraw the organization's data and/or application from a cloud form or to move or share them to another organization without constraint.x Proprietary (P): The cloud service provider is keeping the means of provision under its ownership. Consequently, when operating in clouds that are proprietary, moving data and/or applications to another cloud provider(s) may require significant effort or investment.x Open (O): Open clouds are using technology that is not proprietary. The organization is not constrained to share its data and collaborate with selected parties using the same open technology.III. Architectural Min set: In the original CCM, thiscriterion defines whether the traditional IT perimeters such as network and firewall are operating inside, called Perimeterised (Per), or outside, called De-perimeterised (D-p), the organization. On the other hand, this criterion was modified in [3]and this modification is adopted in C 3F, resulting the following types.x Perimeterise d(Per): Perimeterised meansinfrastructure as a service (IaaS) and platform as aservice (PaaS), or any services, contracts, and supports using infrastructure and platform.x De-perimeterised (De-p):De-perimeterised stands for Software as a Service (SaaS), or any services, contracts, or supports for software/application, since they are restricted by hardware boundary.Figure 2. The Complete Cloud Computing Formation (C 3F)Since the three criteria are mutually exclusive, then there are 3*2*2= 12 forms. Furthermore, each form is to be represented as a 3-tuple element with the following attributes: (Physical Location and Management,Technology Ownership,Architectural Mindset). For example, (Int/Out, O, De-p) is a 3-tuple designating internal /outsourced, open, De-perimeterisedform.IV.IT ACTIVITIES IN THE EDUCATIONAL AND LEARNINGORGANIZATIONSCloud computing can deliver great advantage to an educational and learning organization, with its budget restrictions and sustainability challenges,but only if the organization uses the cloud formation best suited for a particular activity [10]. This necessitates the classification of IT activities in these organizations with respect to some scheme. It is crucial to select the classification criteria that suit the educational and learning environment.Two principles will govern the selection of the classification criteria. First, it is evident that commercial cloud service providers are gaining significant economies of scale in their infrastructure and service-delivery capacities, enabling them to provide enhanced and mature services, when compared to an individual educational and learning organization, no matter how large and complex the organization is. This is an outward principle, leading to the adoption of cloud computing. This makes it evident that cost is not to be considered as a criterion for classification, at least in the long term planning. Furthermore, for educational and learning organizations, the benefits of moving some of the IT services into the cloud may outweigh the risks associated with respect the challenges facing cloud computing.Second, commercial cloud service providers do not sufficiently understand the educational and learning business requirements, at least from the point of view of the educational and learning organizations. This is an inward principle, limiting the use of cloud computing to the non-core organizational services. The two principles are balanced, creating a neutral view for adopting cloud computing.TABLE I.E XAMPLES OF IT ACTIVITIES IN THE EDUCATIONAL ANDLEARNING ORGANIZATIONSensitivityMission CriticalityLow HighHigh x Sensitive ResearchActivitiesx Student Emailx Students Recordsx Staff Recordsx Faculty Recordsx Medical Recordsx Administrative(Finance, Purchasing,etc.)x Backup of SensitiveInformationLow x Alumni Emailx Student Projectsx Websites for Faculty,Students, Staff, andClassesx News & Announcementsx Non-sensitive ResearchActivitiesx Faculty & Staff Emailx E-learningx Mobile learningx Backup of Non-sensitive InformationEquipped with above two principles, the two classification criteria are: mission criticality and sensitivity. Mission criticality parameterizes the relation of the activity to the core services of the organization, whereas sensitivity measures the impact of the activity on the organization, an individual, or group of individuals in the organization. Sensitivity is concerned about privacy, security, data integrity, intellectual property management, audit trails, and other issues. For simplicity, both criteria are categorized as Low and High. Table 1 gives some examples of IT activities in the educational and learning organization for each category.Both criteria can be fine grained to suit the organization environment. The examples of IT services given in Table 1are not meant to be exhaustive but they are typical IT activities in the educational and learning environment. E ach educational and learning should classify their IT services as done in Table 1. The classifications of services provided in the table 1 are representative and the services may be classified differently, depending on the other factors such as national compliance regulations and laws, organizational requirements, etc.V.C LOUD COMPUTING IN EDUCATION AND LEARNINGcation and Learning asa Service (ELaaS)E ach category of the IT activities is then mapped into the appropriate position of in the C3F, as depicted in Fig. 3. The mapping creates ‟Educatio n and Learning as a Service”(E LaaS) and the resulted quadrant is to be called E LaaS Quadrant. This establishes a general conceptual framework for ELaaSE LaaS is symphonious with other cloud terms (e.g., IaaS, SaaS), emphasizing the service concept. However, it is clear from the figure that E LaaS is a hybrid approach, including cloud and non-cloud based solutions. Some IT activities in the educational and learning environment may be best implemented and operated using a traditional non-cloud based system.Figure 3.Mapping the ITactivities into C3F: ELaaS QuadrantB.Step ForwardThe right-hand quadrants in the ELaaS Quadrant show that (Int/In, *, **) and (Int/Out, *, **), where * and ** indicate either Open (O) or Proprietary (P) and either Perimeterised or De-perimeterised, respectively, are very strong candidate approaches. This suggests that an educational and learning organization can take a step forward by establishing its owned cloud computing infrastructure. This enables the organization to be a cloud computing service provider for its own IT needs as well as other educational and learning organizations.VI.CONCLUSIONIt is essential for an educational and learning organization,with its budget restrictions and sustainability challenges, to usethe cloud formations best suited to its IT activities. A cloud computing formation model, called the Complete Cloud Computing Formation Model (C3F), is proposed. It is based onthe Cloud Cube Model (CCM) developed by the Jericho Forum. The IT activities in the educational and learning organizations are then classified with respect to the two criteria: mission criticality and sensitivity. Both criteria are categorized as Low and High.E ach category of the IT activities is then mapped into the appropriate position of in theC3F.

云基础设施购买和消费简化：Cloud Essentials BYOL 和 Universal Cre
At the core of the issue are the legacy on-premises investments that many companies have already made in applications, tools, and infrastructure. Without a clear-cut plan to leverage them in the cloud, organizations often balk at the notion of having to invest yet again in those same solutions.There are several other obstacles that make the process of moving to the cloud more challenging:• When it comes to paying for cloud services, many cloud providers require companies to notify them in advance of the specific cloud services they’ll need, as well as how and where they’re going to run them. This can hamper business responsiveness and result in unpredictably higher operational costs.• With most cloud providers, shifting cloud spending to different platform and infrastructure services as a result of changes in business strategy is often complicated.• Complex cloud payment models from most cloud providers today give organizations limited visibility into (and control over) cloud spending.Many organizations today, while eager to move to the cloud, have concerns around the financial obstacles that often force them to decide between the flexibility of the cloud and the need to reduce costs and risk.Oracle’s new cloud programs, however, address these cloud-adoption challenges by making the journey to the cloud more affordable and by simplifying the way you purchase and consume cloud services. Specifically, Oracle has introduced two new programs for buying and using cloud services that help you get more value from your existing Oracle software investments with less complexity. These programs are Oracle Bring Your Own License (BYOL) to PaaS, and Oracle Universal Credits (UC).Together, these help accelerate your transition to the cloud for greater competitive advantage with tremendous choice and flexibility. Oracle has also lowered PaaS pricing (in some cases up to 94 percent cheaper versus the previous PaaS list price) and reduced IaaS list prices as low as Amazon’s, reducing barriers to cloud entry, as well as risk,for all sizes of businesses. Oracle has always had a BYOL program in placeto allow customers to bring on-premises licensesto Oracle IaaS. With this new extended BYOLprogram, on-premises software such as OracleDatabase and Oracle Middleware can now be portedto corresponding Oracle PaaS services at thenew reduced Oracle PaaS prices.In addition, Oracle Universal Credits make theconsumption of cloud services simple andflexible across PaaS and IaaS by using a singlecontract that doesn’t require you to notify Oracleof changes. You simply pay up front and consumeas you wish. In addition, you can use our UniversalCredits to purchase on-demand access to all currentand future Oracle PaaS and IaaS services (such asdatabase, integration, analytics, security, compute,and storage) with a pay-as-you-go model. You canpay even less by using prepaid pricing for as longas you need.This paper explains how you canbenefit from these new programsand leverage the high automation ofOracle Cloud to accelerate innovationand significantly lower your total costof ownership. Oracle’s new BYOLto PaaS and UC are available todayto support new or existing workloadsacross Oracle Cloud and OracleCloud at Customer.BYOL: License Mobility from On Premises to PaaSOracle BYOL allows you to apply licenses youown for on-premises software for equivalent, highly automated Oracle PaaS services in the cloud. Until now, Oracle customers had been limited to moving on-premises software investments only to IaaS. With this new program, however, licenses canbe used for corresponding Oracle PaaS services for 100 percent workload compatibility and license mobility in Oracle Cloud.Shifting Oracle database, middleware, and analytics licenses to Oracle PaaS provides the lowest possible TCO and greatest value for customers. That valueis further magnified by the power of Oracle Cloud versus the competition. Not only are Oracle IaaS list prices as low as Amazon Web Services’ (AWS), but Oracle Cloud also uses less compute and storage to run Oracle database workloads than AWS. This results in even greater savings. In addition,a large portion of the cost of running a database comes from labor rather than from infrastructure. These costs are reduced with Oracle PaaS, which offers advanced automation of processes and tools associated with the database to handleall sorts of complex configurations automatically. Additionally, Oracle PaaS services run not only on a standard cloud infrastructure; they can also run on a highly specialized database infrastructure (such as Oracle Exadata Cloud Service) givingyou even better performance and reliability.BYOL to PaaS also allows you to transfer your Oracle Multitenant 12c database license from your enterprisesubscription to new Oracle innovations (including the world’s first autonomous database cloud). Oracle Autonomous Data Warehouse Cloud leverages machine learning for automation for more savings.• Self-driving: Eliminates human labor to provision, secure, monitor, back up, recover, troubleshoot, and tune the database. Automatically upgrades and patches itself while running. Elastically grows and shrinks compute or storage without downtime, so you pay only for what you use.• Self-securing: Automatically encrypts all data. Provides automatic security updates with no downtime, along with protection from both external attacks and malicious internal users.• Self-repairing: Delivers automated protection from all planned and unplanned downtime.Oracle delivers lower TCOfor Oracle Autonomous DataWarehouse Cloud in Oraclepublic cloud compared torunning Oracle Database onAWS.

These dramatically simplify how you purchase and consume cloud services by offering a single contract to acquire, expand, transfer, or cancel any and all current and future PaaS and IaaS services. Oracle BYOL and UC build upon Oracle’s commitment to delivering the world’s leading cloud solutions in the simplest, most efficient way for customers. Previously, Oracle introduced its Accelerated Buying Experience, which automates the end-to-end purchasing process, streamlining approvals, removing the need to spend endless cycles negotiating back and forth, and enabling you to order cloud services at the click of a button. The Accelerated Buying Experience is designedto speed time to value and simultaneously freeup resources. Using Oracle’s own SaaS applications, including Oracle Sales Cloud, Oracle Service Cloud, and Oracle Configure, Price, and Quote (CPQ) Cloud, Oracle can now complete orders efficiently and more quickly than ever before. Unlike many of its competitors, Oracle offersboth a fast and simple buying experience, and favorable terms across the broadest set of cloud services. Also, Oracle customers now need only oneagreement for their entire cloud relationship with us.To understand the differences between Oracle’s new Universal Credits and other cloud providers’, let’s look at a typical scenario where a customer buys US$1,000of credits with a provider. As an example, AWS customers need to notify Amazon in advance how they’re going to use those credits—on Redshift, in the West Coast data center, or in the East Coast data center. Customers also need to explain how much is going where, and how much they expect to consume. Based on that information, Amazon calculates a discount and generates a contract.By contrast, Oracle Universal Credits has a far simpler process. You simply commit to a certain amountof spend over a specific period of time (such as US$1,000 over the next 12 months). You aren’t required to determine how much is going to be spent on IaaS or PaaS, for example, or in which data center. You’re free to purchase, consume, or shift spending however you see fit over the course of the time period. Oracle determines which services you use and itemizes them against the purchased credits.• You specify individual servicesand quantities at contract/bookingfor reserved instances• The services and data center forprovisioning are locked into the initialorder for reserved instances• You may need to sell the reservedinstance on the secondary market,buy a new instance, then migrateto that new instance• A new order is required toutilize latest services• You select Monthly Flex and dollaramount at contract signing• You utilize any infrastructureand platform cloud serviceanywhere, anytime• You can switch services as neededwithout notifying Oracle• You can adopt the latest servicesas they’re released without signingan order documentBuying from AWS Buying from OracleThe credits also apply to any new services Oracle releases, such as Oracle Autonomous Database. With Oracle UC, you don’t need a new contract for new services. You simply select the service,and it’s applied against your Universal Credits. Universal Credits are applied to anything you want to use. Data can be moved, for example, from one data center to another without notifying Oracle.The Simplicity of Buyingand Consuming Cloud Services Oracle uniquely provides the most flexibility and choice for cloudpurchasing and consumption, with immediate business benefits:• Bring Your Own License (BYOL) empowersexisting customers with license mobility for OraclePaaS to exchange at new lower PaaS pricing• Universal Credits (UC) make contracts easy andconsumption flexible, allowing customers accessto all current and future PaaS and IaaS solutions• There’s the ability to upgrade PaaS andIaaS services using current subscription• You have access to new serviceswith current subscription• There’s elastic scaling of prepaidPaaS and IaaS instances• There is service portability acrossCloud at Customer and the public cloud• Lower list prices, higher performance, and moreautomation provide the industry’s lowest totalcost of ownershipCapitalize on Oracle Cloud Platform NowWith Oracle’s new BYOL and UC programs, it’s easier than ever for you to purchase and consume all current and future Oracle Cloud solutions. Oracle’s complete, open, secure, intelligent solutions provide maximum flexibility and choice for you to build your own unique path to the cloud rather than follow a provider’s cookie-cutter plan. Oracle’s broad and deep portfolio of services makes it possible for you to address any business challenge by moving to cloud, using emerging technologies, such as artificial intelligence (AI), machine learning, blockchain, chatbots, and more to shift your focus from maintaining IT investments to innovating new ways to compete and succeed.Move workloads.Oracle Cloud Platform provides the choice and freedom to sequence workload migrations however you’d like—from SaaS, PaaS, or IaaS. You can lift and shift apps, databases, and VMs to IaaS without the cost and complexity of manual migrations and rewrites. Or you can lift and shift workloads directly to PaaS, allowing you not only to retire infrastructure and reduce cost (some customers claim up to 60 percent reduction in TCO),but also get the benefits of automationso that you can focus on outcomes versusadministration. In addition, you can improveoverall application performance and leverageanalytics in the cloud.Develop and deploy.Oracle’s integrated, standards-based solutions fordeveloping and deploying apps are technology-agnostic,providing more choice for development environments.Built with DevOps in mind, Oracle includes automationtools for continuous deployment, with integrated securityand management tools for monitoring, compliance,and governance. Oracle also makes it possible to buildmodern cloud-native apps, including microservices, APIs,mobile apps, and chatbots.Connect and extend.Critical to supporting the journey to the cloud is providing a platform that allows customers to connect apps, data, APIs, and content across clouds and on premises. Oracle automates and orchestrates business processes across systems and applications, with the ability to extend capabilities, differentiate, and create modern experiences—for customers or employees.Insights for business transformation.Oracle Analytics Cloud allows customers to visualizebusiness performance by asking any question of any dataset, going beyond dashboards to see hidden signals and explore unanswered questions.

As a student, the internet has had a profound impact on my life, opening up new avenues for learning, collaboration, and personal growth.When I think back to my early years in school, I recall the days when we relied solely on textbooks, encyclopedias, and the limited resources available in our school library. Conducting research was a laborious process, often involving hours of sifting through physical books and journals. If we needed information that wasn't available in our library, we had to wait for interlibrary loans or make trips to larger libraries, which could take days or even weeks.Fast forward to today, and the internet has become an invaluable tool in my academic journey. With just a few clicks, I can access a vast repository of knowledge on virtually any topic imaginable. Online databases, academic journals, and digital libraries have made it easier than ever to find reliable andup-to-date information for my research projects and assignments.One of the most significant advantages of the internet for students like myself is the ability to learn from a diverse range of sources. Online courses, educational videos, and interactive tutorials have opened up new avenues for learning beyond the traditional classroom setting. I can now explore subjects that may not be offered at my school, or delve deeper into topics that pique my curiosity.The internet has also revolutionized the way I communicate and collaborate with my peers and teachers. Online discussion forums, video conferencing tools, and collaborative platforms have made it easier to engage in discussions, share ideas, and work on group projects, even when we're physically separated.Imagine trying to coordinate a group project without the internet – it would involve endless back-and-forth phone calls, meetings, and exchanging physical documents. Today, we can use cloud-based tools to share files, track progress, and provide real-time feedback, making the entire process more efficient and streamlined.Beyond academics, the internet has also played a significant role in shaping my personal and social life. Social media platforms have allowed me to stay connected with friends and family, share experiences, and discover new interests and communities. While there are certainly debates around the potential negative impacts of social media, I believe that when used responsibly, it can be a powerful tool for building connections and fostering a sense of belonging.The internet has also opened up new opportunities forself-expression and creativity. From blogging and vlogging to digital art and music production, the online world has provided aplatform for me to explore my passions and share them with a global audience. This exposure to different perspectives and creative outlets has helped me develop a more well-rounded understanding of the world and challenged me to think outside the box.Of course, with the vast amount of information available online, it's crucial to develop critical thinking skills and media literacy. Not everything on the internet is accurate or reliable, and it's essential to evaluate sources critically andcross-reference information from multiple reputable sources. This ability to discern fact from fiction and to think critically about the information I encounter has become an invaluable skill in the digital age.Despite the many benefits the internet has brought to my life as a student, it's important to acknowledge the potential downsides and challenges that come with this technology. The prevalence of online distractions, such as social media and streaming services, can make it difficult to stay focused and manage time effectively. Additionally, concerns around privacy, cyberbullying, and the spread of misinformation are valid issues that need to be addressed.However, I believe that with proper guidance, education, and responsible use, the advantages of the internet far outweigh the potential risks. As a student, the internet has empowered me to take charge of my learning, collaborate more effectively, and explore new interests and opportunities that were previously inaccessible.Looking ahead, I can only imagine how the internet will continue to evolve and shape the educational landscape. Emerging technologies like virtual and augmented reality, artificial intelligence, and adaptive learning platforms are already showing promise in enhancing the learning experience and personalizing education to individual needs.As I prepare to embark on my future career and lifelong learning journey, I am confident that the skills and knowledge I've gained through the internet will serve me well. The ability to navigate the digital world, locate and evaluate information critically, and leverage online tools for collaboration and problem-solving are invaluable assets in today's rapidly changing world.In conclusion, the internet has truly transformed my life as a student, opening up new avenues for learning, communication, and personal growth. While it's important to use this powerfultool responsibly and critically, I am grateful for the opportunities it has provided and excited to see how it will continue to shape the future of education and beyond.篇3How the Internet Has Changed My LifeAs a student in the 21st century, it's hard to imagine life without the internet. It has become such an integral part of how I learn, socialize, and entertain myself that I often take it for granted. But when I stop to think about it, I realize just how much the internet has transformed my daily existence and opened up new possibilities that previous generations couldn't have even dreamed of.One of the biggest ways the internet has impacted my life as a student is through the vastly improved access to information and educational resources it provides. In the past, students were limited to the books and materials available in their school's library or what their teachers could provide in class. But now, with just a few clicks, I can access a wealth of knowledge on virtually any topic imaginable.Need help understanding a difficult concept from class? A quick online search yields dozens of explanatory videos, tutorials,and articles to supplement what was taught. Have to write a research paper? I can easily find credible sources and academic journals right at my fingertips. The internet has turned my laptop and smartphone into gateways to the collective knowledge of humanity.This access to information has not only made me a more self-directed learner but has allowed me to explore new subjects and topics that pique my interests beyond what is covered in my formal classes. I can satisfy my intellectual curiosity by diving deep into online courses, podcasts, and virtual museums on everything from ancient history to theoretical physics to digital art. The internet has opened up a world of self-guided learning and intellectual growth that simply wasn't possible before.Of course, the internet's impact extends far beyond just academics. It has also dramatically shaped how I socialize and interact with others. In many ways, it has made my world much smaller by allowing me to easily connect with people across the globe. Through social media, messaging apps, and online communities, I've been able to meet and develop friendships with people from all walks of life that I never would have encountered otherwise.At the same time, the internet has paradoxically made my world much bigger too. It has exposed me to diverse cultures, perspectives, and ways of life that have expanded my horizons. Watching videos from international creators, reading articles from foreign news outlets, and interacting with people from around the world has given me a more global mindset. I've gained a deeper appreciation for the diversity of human experiences.Additionally, the internet has opened up new avenues for self-expression and creativity. Platforms like YouTube, Instagram, TikTok and personal blogs have allowed me to share my ideas, art, and stories with a potential audience of millions. As a teenager trying to find my voice and identity, having these outlets has been incredibly empowering and validating.On the flip side, the internet has definitely impacted my attention span and ability to focus for long periods. With the endless stream of content, videos, memes and messaging notifications constantly vying for my attention, I've noticed it's become harder for me to concentrate deeply on things like reading books or working on extended projects. It's an area of my life that I'm still striving to find more balance in.The internet has also changed my understanding of privacy and personal boundaries. So much of our lives are now lived online, from the childhood photos our parents posted to the not-so-flattering Snaps and TikToks from crazy nights out with friends. This paradoxical blending of public and private has made me think more critically about my digital footprint and the permanence of anything I post or share.Perhaps one of the most significant impacts the internet has had on my life is the amazing opportunities for entrepreneurship and income generation that it has enabled. The old career paths that existed for previous generations have been totally disrupted. Thanks to the internet, it's now possible to build an immensely popular YouTube channel, start an e-commerce business from your bedroom, publish an e-book or online course, or offer services like graphic design, copywriting and coding to a global market.The internet has opened up a new frontier of possibilities to create value, build an audience, and generate income in ways that simply didn't exist a couple decades ago. To see kids not much older than me become self-made millionaires through avenues like YouTube, Twitch live-streaming or e-commerce is both inspiring and a bit mind-boggling when you think about it.While I personally haven't taken the entrepreneurial plunge yet, I love that the internet has created these on-ramps to earn money by pursuing your skills and passions.At the end of the day, I know I'm incredibly fortunate to be coming of age in the internet era. It has unlocked access to a world of knowledge, connection, and opportunity that is shaping my development in profound ways. While it's not without its downsides and struggles, the benefits of the internet have been revolutionary for myself and young people everywhere.As I look ahead to my future after high school and into college, there's no doubt in my mind that the internet will continue to impact my life in ways I can hardly even imagine right now. New technologies, platforms, and internet-enabled innovations are emerging every day that will open up possibilities that may seem like science fiction today. I'm excited to see how the internet continues to shape and change my journey through life.While generations before me lament all the things that have been "lost" in the digital age, I'm endlessly fascinated by the new realities, skills, and modes of expression that the internet is enabling. It has become the foundational layer that underpins so much of how I live, learn, work, play, and see the world. For thosereasons, I'm deeply grateful to be a digital native in the internet era. Its impact on my life has been utterly transformative.。

高等教育中技术对学习的影响英语作文
高等教育中技术对学习的影响英语作文全文共6篇示例，供读者参考篇1The Magical World of Tech and LearningHey there friends! It's me, Tommy, back again to tell you all about the awesome world of technology and how it's changing the way we learn in schools. Now, I know what you're thinking - "But Tommy, you're just a kid in elementary school, what do you know about higher education?" Well, let me tell you, I may be small but my brain is huge and I've been doing some serious research on this topic.You see, my big sister Sarah is in college right now, studying to become an engineer. And let me tell you, the way she learns is like something straight out of a science fiction movie! It's all tablets, apps, virtual reality headsets, and super-duper computers that can do crazy calculations in the blink of an eye. Gone are the days of just sitting in a lecture hall, scribbling notes as a professor drones on and on. Nope, these days it's all about interactive, hands-on, cutting-edge technology that makes learning way more fun and engaging.One of the coolest things Sarah showed me is these nifty little apps that basically act like digital flashcards and study guides. So instead of lugging around a massive textbook, she can access all the key info and practice problems right on her tablet or phone. And get this - some of these apps even use games and quizzes to help reinforce the material in a really fun way. It's like getting to level up your brain power while feeling like you're just playing a video game. How awesome is that?But that's not all, folks. Sarah also gets to use these wild virtual reality simulations for some of her engineering classes. Instead of just looking at diagrams on a flat screen, she can put on a VR headset and suddenly be transported into a 3D model of a jet engine or a nuclear reactor. She can walk around it, examine every tiny part up close, and even run simulations to see how it all works together. It's honestly like magic, and it helps her understand these crazy complex systems way better than just reading about them could ever do.And you know what else? A lot of Sarah's classes use these online discussion boards and video chat rooms so students and professors can interact and collaborate even when they're not physically in the same place. They can share ideas, ask questions, work through problems together - it's like having a virtual studygroup available 24/7. No more being stuck on a tricky concept until the next class meeting - you can just hop online and get help right away.Now, I know all this high-tech edu-tainment sounds pretty awesome, but you might be wondering - is it actually better for learning than the old-fashioned methods? Well, according to my very scientific research (which mostly involved pestering Sarah until she explained it to me), the answer is a big fat YES! Tons of studies have shown that when lessons involve interactive elements, hands-on activities, and visual aids like animations and simulations, students are way more engaged and actually retain way more information.The human brain is basically hardwired to pay attention to moving pictures, immersive experiences, and gamified content - it's a lot harder to zone out and start daydreaming when you're actively participating instead of just sitting still and listening. Plus, all these fancy new tools make abstract or super complex concepts way easier to understand by breaking them down into bite-sized, visual chunks.So what does the future hold as this edtech revolution continues? Well, from what I can tell, things are only going to get even more amazing and mind-blowing. Imagine holographiclectures that make it seem like the professor is right there in the room with you. Or virtual campus tours that let you explore colleges from the comfort of your bedroom. Heck, with things like augmented reality, you might soon be able to wave a magic wand and turn your dorm room into the practical potions classroom at Hogwarts! Okay, maybe that last one is a bitfar-fetched...but you get the idea.The possibilities really do seem endless when you combine the power of human intelligence and creativity with the rapid advancements happening in educational technology. It's an exciting time to be a learner at any age or level. Who knows what far-out, futuristic tools the colleges of tomorrow will use to educate the next generation of brilliant scientists, artists, leaders and innovators?One thing's for sure though - the days of learning being a dry, boring experience of just sitting still and absorbing information like a sponge are long gone. Technology has opened the door to making education engaging, immersive, personalized and downright fun. And as a kid who's grown up surrounded by tablets, smartphones and video games, I can tell you that's a path that will lead to way more effective learning for students like me.So to all you skeptics out there who think adding more techto the classroom is just a bunch of expensive gimmickry, I say "Oh ye of little faith!" Used properly, all these awesome tools and toys have the potential to unlock a whole new world of understanding - one where even the trickiest concepts can be conquered through interactive exploration rather than tedious memorization. And at the end of the day, isn't that what true learning is all about?So buckle up, my friends! The classrooms of the future are going to be a wild, immersive ride filled with more gigabytes of knowledge than you can shake a stylus at. I don't know about you, but I can't wait to see what amazing adventures in learning lie ahead. Class dismissed!篇2The Magic of Technology in Big Kid SchoolWow, I can't wait until I'm old enough to go to big kid school! My older cousin is in college and he tells me all about the awesome technology they use to learn. It sounds like so much fun!In elementary school, we just have basic computers for typing practice and research. But in college, they have all sorts ofcrazy cool tech tools. My cousin says they get to use virtual reality headsets in some classes! Can you imagine? You can like, walk around inside a 3D model of a human body and see all the organs and stuff. Or explore ancient Rome like you're actually there. How wild is that?They also have these digital tablets that are way more advanced than the basic ones we use. The professors can write notes on the screens and it records everything. Then the students can view the notes later on their laptops or phones. No more frantically trying to copy down every word! The tablets make diagrams and drawings really easy too. The professor just sketches it up and beams it right to the students' devices. Genius!Speaking of laptops and phones, college kids use them for practically everything nowadays. Not just for taking notes, but for interactive lessons, online discussions, watching video lectures, taking tests and quizzes, turning in assignments...you name it. My cousin never has to lug around a million textbooks and binders. It's all on his laptop and cloud storage. Soooo convenient!Another crazy thing is online classes. Like, you don't even have to physically be on campus. You just log into a video chatand the professor teaches the whole class over the internet! People can basically get degrees from anywhere in the world now. My aunt is taking an online MBA program and she never leaves her living room. She says the discussions are still really engaging because they use all these neat collaboration tools and video breakout rooms and stuff. Honestly, it sounds better than having to schlep to campus in the middle of the night after work.But don't worry, there's still plenty of in-person learning too.I hear the labs and studios have unbelievable equipment to get hands-on experience. Like in engineering, they've got 3D printers, laser cutters, robotics workshops...everything you could dream of to build prototypes and work on real products. And for creative majors like film or design, the facilities are decked out with professional-grade video equipment, soundproofed audio rooms, and lifelike animation studios. My cousin is studying music production and he gets to mess around with these insane mixing boards, synthesizers and recording rigs that are worth millions of dollars. He's basically becoming a real music producer before even graduating!Classes have awesome technology too, not just the labs. Lecture halls are starting to look like spaceships with these giant curved screen displays that make presentations and videos popoff the walls. My cousin says it's like being inside an IMAX movie theater! Some rooms even have cameras that can automatically focus and zoom in on whoever is speaking. There are also these "smart boards" that capture everything the professor writes or projects and shares it online for students to reference. No more missing important stuff if you space out for a bit!Oh, and let's not forget online libraries and research databases. We're so lucky these exist now! My cousin searches academic journals, ebooks, documentaries, you name it, all from the comfort of the student center or his bed. No more getting lost in the terrifying book labyrinths of yore. Everything is just a few clicks away. Pretty much all knowledge in the entire world is at his fingertips thanks to the internet. I can't wait to access that treasure trove of information!I could go on and on about the technical marvels in higher ed, but I'm already running out of words. Let's just say college seems like a wonderland of gadgets, gizmos, and apps that make learning easier, more immersive, and way more fun than the old school methods of yore. Heck, with all the virtual reality, online classes, and streamed lectures, they hardly even need physical campuses and classrooms anymore!Maybe by the time I'm old enough for big kid school, we'll all just get Matrix-style learning uploads beamed straight into our brains. Enter the Metaverse, download Calculus 301, boom...done! How cool would that be? I'm gonna start saving my allowance now for inevitable tuition hikes to pay for that brain jack technology. A kid can dream, right?篇3Here's an essay on the impact of technology on learning in higher education, written from the perspective of a young student, approximately 2000 words long:The Impact of Technology on Learning in Higher EducationBy a Young StudentHi there! My name is Emma, and I'm a 10-year-old student who loves learning about new things. Today, I want to share my thoughts on how technology is changing the way people learn in colleges and universities.When I think about technology and higher education, the first thing that comes to mind is online classes. You see, with the internet and video conferencing tools like Zoom, students can now attend classes without even leaving their homes! Isn't thatamazing? Imagine being able to learn from the comfort of your own bedroom, wearing your favorite pajamas.But online classes are just the beginning. Technology has also brought us so many new ways to access information and learn at our own pace. There are online libraries with millions of books, articles, and research papers that students can access with just a few clicks. And then there are educational websites, video tutorials, and interactive learning apps that make learning fun and engaging.Speaking of apps, did you know that there are apps that can help you study more effectively? Some apps use flashcards and quizzes to help you memorize important concepts, while others use games and puzzles to make learning more enjoyable. And let's not forget about virtual reality (VR) technology, which can transport you to distant lands, historical events, or even inside the human body! With VR, learning becomes an immersive and unforgettable experience.Another way technology is changing higher education is by making it easier for students to collaborate and work together on projects. With tools like Google Docs and cloud storage, multiple students can work on the same document or project at the same time, even if they're in different parts of the world. Thisfosters teamwork and helps students develop important skills like communication and problem-solving.But technology isn't just about new tools and gadgets; it's also changing the way professors teach and present information. Many professors now use interactive whiteboards, presentation software, and multimedia to make their lectures more engaging and visually appealing. Some even use social media to connect with their students and share additional resources or hold online discussions.Despite these challenges, I believe that technology has had an overall positive impact on higher education. It has made learning more accessible, engaging, and personalized, allowing students to learn at their own pace and in ways that suit their individual needs and learning styles.But technology is not a replacement for good teachers and in-person instruction. It's important to strike a balance and use technology as a tool to enhance and supplement traditional learning methods, not replace them entirely.As I look towards my own future in higher education, I'm excited to see how technology will continue to shape and transform the learning experience. Perhaps by the time I'm in college, we'll have holographic classrooms or brain-computerinterfaces that allow us to download information directly into our minds (just kidding!). Whatever the future holds, I'm confident that technology will continue to play a vital role in making education more accessible, engaging, and effective for students around the world.Well, those are my thoughts on the impact of technology on learning in higher education. What do you think? How has technology changed the way you learn or teach? I'd love to hear your perspectives!篇4The Magic of Screens and Gadgets for LearningHi there! My name is Timmy and I'm 8 years old. Today I want to tell you all about how cool technology is for learning new things in school and college. My older brother Joey is in university, so I've seen him use lots of awesome gadgets and websites for his studies. It's like magic!First off, let me tell you about computers and laptops. These things are like little brains that can store tons of information! Joey uses his laptop for writing his assignments and papers. Instead of having to use a pen and paper, he can just typeeverything up super fast. And if he makes a mistake, he can fix it easily without having to scratch things out. Isn't that neat?But computers aren't just for writing. They also let you look up anything you want to learn about on the internet. The internet is this massive library of knowledge from all over the world, right at your fingertips. If Joey needs to research a topic like ancient Egypt or photosynthesis, he can find websites, articles, videos, and images all about it in seconds. When I'm older and in university, I'll be able to use the internet to learn absolutely anything!Speaking of videos, those are one of my favorite ways tech helps us learn. There are so many educational videos and movies online and on TV these days. They make topics way more interesting and easier to understand than just reading from a book. My science teacher plays these cool videos that show how things like volcanoes, black holes, and atoms work using animated graphics and characters. I remember all the concepts so much better that way!Another amazing thing is that with modern technology, you can take classes from actual experts anywhere in the world without even leaving your home. It's called "online learning" or "e-learning." My uncle took an entire computer programmingcourse online from a famous school in California, even though he lives here in Illinois. The teacher gave video lectures and they used chat rooms and forums to discuss the material. How incredibly convenient is that?But it's not just about learning at home or school. Thanks to mobile devices like tablets and smartphones, you can learnon-the-go too! Joey puts learning apps on his phone for studying vocabulary words, watching educational videos, or even taking practice quizzes when he has some free time. My parents let me play interactive games on their tablets that teach me math, spelling, geography, you name it. I'm having so much fun learning with those gadgets, it doesn't even feel like work.Modern technology has also been a huge help for people with disabilities or learning differences. My friend Charlie has dyslexia, which makes reading really hard for him. But on his computer, he can use special software that reads ebooks and websites out loud to him. Other students who can't see well can make text supersize or use voice controls. How incredible that we have tools to make education accessible for absolutely everyone!But overall, I think technology has been an absolutely amazing tool for learning at all levels - from kindergarten to grad school and every age in between. I can't wait until I get to useeven more cool gadgets and websites to explore the world and gain knowledge as I keep growing! Modern tech is truly making the world of education an awesomely fun and interactive place. The future of learning is so bright!篇5Technology is Super Cool in College!Hi there! My name is Timmy and I'm 8 years old. I love playing video games, watching YouTubers, and using my parents' iPad. Technology is so much fun! I can't wait until I'm older and get to use even more amazing tech stuff when I go to college.My big brother Jake just started university last year. He's told me all about the awesome technology they have on campus and in his classes. It sounds like colleges these days are filled with the latest gadgets and gizmos to help students learn better. I'm really excited thinking about all the cool tech I'll get to use when it's my turn!One of the neatest things Jake described is these big touchscreen displays they have in a lot of classrooms. The professors can write digital notes, show videos, and even do interactive lessons right on the massive screens. Jake says it'sway more engaging than just listening to a lecture with someone writing on an old chalkboard or whiteboard. With all the colorful visuals and multimedia, it's easier for students to pay attention and understand the material.They also have these "clicker" remotes that students can use to answer questions the professor asks during class. It's like a high-tech version of raising your hand, except your answer is recorded instantly. Jake says it's a fun way to keep everyone involved rather than just having a few students speak up. If you get a question wrong, the professor can tell right away that you need some extra help on that topic.Another really innovative thing colleges use now is virtual reality headsets for certain subjects. I can't even imagine what that must be like! Jake got to Experience dissecting a virtual frog in his biology lab. Instead of cutting up a real frog (which seems kind of gross), he just put on the VR goggles and got to look at a 3D model from every angle. He said it was just like being shrunk down and examining the frog up close without any smelly animal guts. VR also lets you explore locations or historical events that you're studying about. Jake's roommate wore VR goggles to virtually walk around Ancient Rome for his classics course. That's like having a field trip without ever leaving the classroom!For a lot of classes now, you don't even need to buy expensive physical textbooks anymore. Jake's professors just assign digital books that get loaded onto tablets or e-readers instead. That sure saves a lot of money and backpack weight compared to carrying a stack of huge books everywhere! The digital textbooks often have extra features too, like videos, quizzes, and search tools built right into them. You can easily find specific information and learning gets a lot more interactive.Universities are also using more online systems and apps to help students learn these days. Most classes have an online portal where professors post assignments, lecture notes, grades, and other important updates. You can even take quizzes and submit homework online instead of printing out paper copies. It makes everything easier to keep track of and ensures nothing gets lost or misplaced.There are also lots of educational apps and websites that teach course material in a more engaging gamelike format. For example, Jake uses this anatomy app where you can peel off virtual layers of the human body and explore all the bones, organs, muscle systems and more. Way cooler than just staring at diagrams in a textbook!Even outside of class, technology is super helpful for studying. If Jake ever needs tutoring help or has questions, he can easily video chat with student tutors from anywhere. Campus libraries and study spaces also have powerful computers loaded with all kinds of software for writing papers, making presentations, coding programs, and more. There are high-tech printers, scanners, and even 3D printers available too if you need to print something out.From what my brother tells me, going to college nowadays is like being in an awesome tech playground! Every resource at your fingertips is enhanced by incredible new technologies. Learning just seems so much more fun and interactive compared to the old school chalkboards, textbooks and paper worksheets we use in elementary school.I know college will be really challenging with a ton of hard work. But having all these cutting-edge tools available will definitely make it an amazing experience. Just thinking about things like virtual reality lessons, touchscreen classrooms, and interactive apps gets me really excited to further my education someday. Technology is the coolest! I bet universities will have even crazier innovations by the time I get to college in 10 more years. I can't wait to see what the future of learning looks like!篇6Technology and Learning in Big Kid SchoolWow, higher education is so cool! That's where all the big kids go to learn really hard stuff after they finish regular school. My older brother is in college now, and he tells me all about the crazy things they do there. It's like a whole different world!From what I can tell, technology plays a huge role in how the big kids learn at university. My brother is always on his laptop or tablet, typing away or watching videos for his classes. It's kind of like being in school, but not really. Instead of teachers standing in front of a chalkboard, a lot of his learning happens online through these things called "learning management systems."I asked my brother to explain what a learning management system is, and he said it's kind of like a virtual classroom. All his course materials, assignments, and even some lectures are posted there. He can submit his work, take quizzes, and participate in discussions with his classmates and professors. It sounds super high-tech!But that's not all – technology is integrated into pretty much every aspect of higher education these days. For example, many universities use digital textbooks instead of physical ones. Mybrother says it's really convenient because he can access his textbooks from anywhere and make notes directly in them. No more lugging around a heavy backpack full of books!Another way technology is used is through online collaboration tools. Since a lot of university work involves group projects, my brother and his classmates use things like video conferencing, shared documents, and project management apps to work together remotely. That way, they don't all have to be in the same room to get things done.I think one of the coolest uses of technology in higher education is for lab work and simulations. In some of his science classes, my brother gets to use virtual reality and augmented reality to visualize and interact with complex concepts. He says it's like being shrunk down and entering the microscopic world, or seeing things from all angles that would be impossible in the real world. I can't even imagine what that must be like!But with all this technology, there are bound to be some downsides too. My brother complains sometimes about having too much screen time and feeling overwhelmed by all the digital information coming at him. He says it can be hard to stay focused and motivated when everything is online and there are so many distractions.There are also concerns about things like online cheating, cyberbullying, and data privacy when so much of the university experience happens in the digital realm. My brother said his school has strict policies and tools in place to try to prevent those kinds of issues, but it's still something they have to be really careful about.Overall, though, it seems like technology has had a mostly positive impact on higher education. It's made learning more accessible, interactive, and collaborative in a lot of ways. Of course, nothing can truly replace the value of in-person instruction and face-to-face interactions, but technology has become an integral part of how the big kids learn and navigate university life.Who knows, by the time I'm old enough for college, there might be even more crazy high-tech stuff going on! Maybe we'll all be learning in fully immersive virtual reality classrooms or something. For now, I'll just have to live vicariously through my brother's stories and be amazed at how different (and cool) higher education is these days compared to when I'm in elementary school.。

cloudy知识点总结
cloudy知识点总结The Basics of Cloud ComputingCloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).Cloud computing provides a simple way to access servers, storage, databases, and a broad set of application services over the Internet. A cloud services platform such as Amazon Web Services owns and maintains the network-connected hardware required for these application services, while you provision and use what you need via a web application.Cloud computing has several key advantages:1. CostCloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, and the IT experts for managing the infrastructure. It’s all done by someone else.2. SpeedMost cloud computing services are provided self-service and on-demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning.3. Global scaleThe benefits of cloud computing services include the ability to scale elastically. In cloud speak, that means delivering the right amount of IT resources—for example, more or less computing power, storage, bandwidth—right when they’re needed, and from the right geographic location.4. ProductivityOn-site data centers typically require a lot of “racking and stacking”—hardware set-up, software patching, and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals.5. PerformanceThe biggest cloud computing services run on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computinghardware. This offers several benefits over a single corporate data center, including reduced network latency for applications and greater economies of scale.Types of Cloud ServicesCloud computing services are broadly divided into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).1. Infrastructure as a Service (IaaS): This is the most basic category of cloud computing services. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis.2. Platform as a Service (PaaS): PaaS is IoT of a cloud computing service that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.3. Software as a Service (SaaS): SaaS is a method of delivering software over the Internet, on demand, and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching.Benefits of Cloud ComputingCloud computing can offer many benefits for businesses of all sizes. Some of the key benefits of cloud computing include:1. Cost-EffectiveCloud computing eliminates the need to make large upfront investments in hardware and software. Instead, you can pay for what you use on a subscription-based model, which can often be more cost-effective, particularly for small businesses.2. ScalabilityCloud computing services offer the ability to quickly scale resources up or down based on demand. This means you have the flexibility to grow your business without the need for significant capital investment.3. AccessibilityWith cloud computing, you can access your files, applications, and data from any location with an internet connection. This level of accessibility can be particularly useful for businesses with remote workers or multiple office locations.4. CollaborationCloud computing services often include collaboration tools, such as file sharing and online document editing, that can help improve teamwork and productivity.Challenges of Cloud ComputingWhile cloud computing offers many benefits, there are also some challenges associated with adopting cloud services. Some of the potential challenges of cloud computing include:1. SecuritySecurity is a major concern for businesses considering cloud computing. You need to ensure that your cloud provider has robust security measures in place to protect your data from unauthorized access, data breaches, and other security threats.2. ComplianceDepending on your industry and location, there may be specific compliance and regulatory requirements that your cloud provider needs to meet. You need to ensure that your cloud provider can meet these requirements to avoid potential legal and financial implications.3. DowntimeCloud service downtime can disrupt your business operations and impact your productivity. It's important to ensure that your cloud provider has reliable infrastructure and service level agreements in place to minimize the risk of downtime.4. Data IntegrationIf you're migrating from on-premises systems to the cloud, you may encounter challenges with integrating your existing data and applications with cloud services. It's important to consider data integration requirements when planning your cloud migration.The Future of Cloud ComputingAs technology continues to evolve, the future of cloud computing is likely to be shaped by several key trends, including:1. Edge ComputingEdge computing is an emerging trend in cloud computing that involves processing data and running applications closer to the source of the data, rather than relying on centralized cloud servers. This can help reduce latency and improve performance for applications that require real-time data processing.2. Multi-Cloud EnvironmentsMany businesses are adopting a multi-cloud strategy, using multiple cloud providers to meet their specific needs and avoid vendor lock-in. This trend is likely to continue as businesses seek to maximize flexibility, performance, and cost-effectiveness.3. Serverless ComputingServerless computing, also known as Function as a Service (FaaS), is a cloud computing model that allows developers to run code without provisioning or managing servers. This can help simplify application development and reduce infrastructure costs.4. Artificial Intelligence and Machine LearningThe integration of artificial intelligence (AI) and machine learning (ML) into cloud computing services is likely to continue, enabling businesses to leverage advanced capabilities for data analysis, automation, and decision-making.ConclusionCloud computing offers many benefits for businesses, including cost savings, scalability, accessibility, and collaboration. However, there are also challenges associated with adopting cloud services, such as security, compliance, downtime, and data integration. As technology continues to evolve, the future of cloud computing is likely to be shaped by trends such as edge computing, multi-cloud environments, serverless computing, and the integration of AI and ML. Overall, cloud computing will continue to play a crucial role in the digital transformation of businesses across all industries.。
