What are the advantages of using cloud computing?答案：Cloud computing offers several advantages, including:- Cost savings: Companies can reduce their infrastructure costs by using cloud services instead of maintaining their own hardware.- Scalability: Cloud services can easily scale up or down based on demand, allowing businesses to only pay for what they need.- Flexibility: Users can access cloud services from anywhere with an internet connection, enabling remote work and collaboration.- Disaster recovery: Cloud providers often have backup systems in place, ensuring data can be recovered in case of a disaster.- Automatic updates: Cloud services are typically updated regularly by the provider, ensuring users have access to the latest features and security patches.2. Explain the difference between HTTP and HTTPS.答案：HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting data over the internet. It is not secure, meaning that the data being transmitted can be intercepted and read by anyone. HTTPS (Hypertext Transfer Protocol Secure), on the other hand, is a secure version of HTTP. It uses encryption to ensure that data is encrypted before transmission, making it much more difficult for hackers to intercept and read. HTTPS is commonly used for secure online transactions, such as submitting credit card information or personal details.四、编程题请编写一个Python程序，实现计算圆的面积和周长的功能。

Linus had an interest in Minix, a small UNIX system, and decided to develop a system that exceeded the Minix standards. He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released. The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone. It is this kernel that forms the base around which a Linux operating system is developed. There are now literally hundreds of companies and organizations and an equal number of individuals that have released their own versions of operating systems based on the Linux kernel.Apart from the fact that it’s freely distributed, Linux’s functionality, adaptability and robustness, have made it the main alternative for proprietary UNIX and Microsoft operating systems. IBM, Hewlett-Packard and other giants of the computing world have embraced Linux and support its ongoing development. More than a decade after its initial release, Linux is being adopted worldwide primarily as a server platform. Its use as a home and office desktop operating system is also on the rise. The operating system can also be incorporated directly into microchips in a process called “embedding” and is increasingly being used this way in appliances and devices.Throughout most of the 1990’s, tech pundits, largely unaware of Linux’s potential, dismissed it as a computer hobbyist project, unsuitable for the general public’s computing needs. Through the efforts of developers of desktop management systems such as KDE and GNOME, office suite project and the Mozilla web browser project, to name only a few, there are now a wide range of applications that run on Linux and it can be used by anyone regardless of his/her knowledge of computers.1. About the starting of Linux, which of the following is true?A. It was developed by a group of software engineers.B. It was initiated by a US student.C. Microsoft experts initiated this language.D. A Finnish student started Linux.2. The meaning of word “kernel” is closest to which of the following?A. peripheralB. shellC. coreD. bottle3. Linux is welcomed for all the following reasons EXCEPTA. free distributionB. adaptabilityC. user friendlinessD. robustness4. What can be inferred about Linux in the 1990’s?A. It was very popular.B. It was not very popular.C. It was expensive.D. It was not developed yet.5. About the future of Linux, which of the following is right?A. It will remain active only as a server operating system.B. It will totally replace Windows systems.C. It will be increasingly used by home users.D. It’s hard to tell.三、Dictation四、what would you say1. Ask Mike, one of your co-workers, to dinner tonight.2. You friend needs your help with a report, but you don’t have enough time.3. You are calling Mr. Brown, a major client, but he’s not at his desk. Leave a message to tell him that his computer has been fixed and he can pick it up on weekdays.4. Please introduce your technical background.5. What have you learnt about software programming?五、你叫Michael,在一家IT公司工作。

Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallelcomputing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems. Research into artificial intelligence (AI) has led to several other new styles of programming.2.High-level languages are commonly classified asprocedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.四、汉译英题（20分）最著名的互联网例子是因特网。

On the other hand, an interpreter translates and executes the source code line by line. Python and Ruby are examples of languages that use interpreters.2. Object-oriented programming (OOP) is a programming paradigm that organizes data and functions into reusable objects. It focuses on the concept of classes and objects, allowing for code reuse and encapsulation. An example of a programming language that uses OOP is Java, where objects are instances of classes and can interact with each other through methods and attributes.3. The client-server model is a distributed computing architecture wherea server provides services or resources to multiple clients. The clients request and receive these resources through the network. An example of a commonly used protocol within this model is the Hypertext Transfer Protocol (HTTP), which is used for communication between web browsers (clients) and web servers.四、论述题Artificial intelligence (AI) has had a significant impact on various industries. In healthcare, AI is being used for diagnoses and treatments, analyzing medical images, and personalized medicine. For example, AI-powered algorithms can help detect diseases like cancer at an early stage, leading to better treatment outcomes. In finance, AI is utilized for fraud detection, algorithmic trading, and customer service. AI algorithms can analyze large amounts of financial data to identify patterns and make accurate predictions. In transportation, AI is being employed for autonomous vehicles, traffic management, and logistics optimization. Self-driving cars, for instance, use AI algorithms to navigate and make decisions on the road.The implementation of AI in these industries brings about many benefits, such as increased efficiency, improved accuracy, and cost savings. AI systems can process and analyze vast amounts of data much faster than humans, leading to faster and more accurate results. However, there are also challenges to consider. Privacy and security concerns arise as AI systems handle sensitive information. There is also the worry of job displacement, as AI automation may replace certain human tasks. Additionally, ethical considerations need to be addressed, such as bias in algorithms and the potential for AI to be used for malicious purposes.Overall, the impact of AI on various industries is undeniable. It has the potential to revolutionize healthcare, finance, transportation, and many other sectors. However, careful implementation and regulation are necessary to ensure its responsible and beneficial use.。

比较题1.SRAM and DRAM*RAM is short for random access memory.@Static RAM(SRAM) keeps data in the main memory,without frequent refreshing,for as long as power is supplied to the cicuit. SRAM is very fast but it is much more expensive than DRAM and takes more space than DRAM. Dynamic RAM(DRAM) is the most often used RAM in today's computer.DRAM can hold its data if it is refreshed by special logic called the refresh circuit.It is much cheaper and take much less space than DRAM.2.System software and Application software*What is software?Collection of programs is called software .*What is computer softwar?It is defined as the instructions and associated data , stored in electronic format , that direct the computer to accomplish task.*what is the shareware ?Shareware is copyrighted software marketed under a “try before you buy” policy.@Systemsoftware is the stuff that make your computer work.The application software is generally the computer programs which are used for the purpose of performing special tasks using a computer,it trains the PC‟s brain for higher cognitive functions rather than just keeping the PC alive and connected to the other.*Examples about Application Software:(1)Accounting software(2)Collaboratire software(3)Compilers and Interpreters(4)Computers Games(5)Database(6)Educational software(7)E-mailN and W ANLAN:A LAN is a high-speed data network that covers a relatively small geographic area .It typically connects workstations, personal computer, printers, servers, and other devices.W AN:A W AN connect multiple geopgraphically nearby LANs to one another over great geographic distances. The speed available on a W AN waries depending on the cost of the connections and may be low. W ANs opeate using routers , which can “choose ” the most appropriate path for data to take to reacha network node.4.What's the difference between Software Engneering & System Engneering ?@System Engineernig is concerned with all aspects of computer based systems developmentincluding hardware ,software and process engineering.Software Engineering is part of this more general process.5.CRT & LCD@CRT: Calhoole ray lube displays had a standarditool form factor owing to the required shape of heavriy vacuum tubeLCD;Liquid cryslal Displays have a new seirse of style.Free from the bulky shap of CRT,today's flat panel vendors are letting their imaginations run free with monitors that are colourd and shaped to match a design concept.*Advantage of LCD monitor①LCD monitor consume less power②Do not produce electromagnetic radiation as CTRs do③Are right and slim in size④Do not flickers like CRT’s⑤Full viewable size6.Synchronous & Asynchronous@S:you need two separated cables with every clock pulse one data bit is transfermed.A:transmission clock and data are tranfermed with only one cable.7.RISC & CISC@CISC:Complex Instruction Set ComputerIt is microprocessor designIt is used to transulations are complex to machine understand;It is need large memory area;It is very slow in processRISC:Reduced Instruction Set ComputerIt is advanced microprocessor designIt is reduced the complex Set of CISCIt is need minimem-storageIt is very fast to compare with CISC8.Switch & Router@9.Windows OS and Unix OS@Windows OS：Be easily understood.Unix OS:The UNIX OS was desiged to let a number of programmers access the computer at the same time and share its resources.10.Multitasking & Multiuser@Multitasking：Many computers do just one thing at a time ,as anyone who uses a PC laptop can attest. Try logging onto your company …s network while opening your browser and while opening a word processing program .Chances are the processor will freeze for a few seconds while it sorts out the multiple instructions. Multiuser:The same design which permits multitasking permits multiple users to use the computer .The computer can take the commands of a number of users –determined by the design of the computer – to
