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。

The Internet, then known as ARPANET, wasbrought online in 1969, which initiallyconnected four major computers at universitiesin the southwestern US . The early Internet wasused by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personalcomputers in those days, and anyone who used it, whether a computer professional or an engineeror scientist or librarian, had to learn to use a very complex system.The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.(四) Choose the best answer according to Passage C.（根据上文的内容选择正确的答案。

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.。

The term coder is used to describe . 4. In order to solve a computational problem, you can let a person or a to do it. Passage C The Internet, then known as ARPANET, was brought online in 1969, which initially connected four major computers at universities in the southwestern US . The early Internet was used by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system. The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and te were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standa by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources. In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network. Since the Internet was initially funded by the government, it was originally limited to research, education, and governme uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.

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。

DNS stands for Domain Name ___________.答案: System3. 简答题1. What is the difference between TCP and UDP?答案: TCP (Transmission Control Protocol) is a connection-oriented protocol, which means it establishes a connection between the sender and receiver before transferring data. It ensures that all packets are received in the correct order and provides error checking. UDP (User Datagram Protocol), on the other hand, is a connectionless protocol that does not establish a direct connection before transmitting data. It does not guarantee packet delivery or order but is faster and more efficient for time-sensitive applications.2. What is the purpose of an operating system?答案: An operating system (OS) is a software that manages computer hardware and software resources and provides common services forcomputer programs. Its primary purpose is to enable the user to interact with the computer and provide a platform for running applications. It manages memory, file systems, input/output devices, and multitasking. The OS also handles system security and resource allocation to ensure optimal performance.4. 解答题请参考下文并给出自己的解答。

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, distributedcomputing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallel computing 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。

When this software was to be maintained by another set of people, it used to bea nightmarish experience. When large commercial projects were to be handled, it used tobe an almost impossible task to keep the time and budget under control, and projectsused to get delayed and many projects were abandoned halfway. There was no systematicprocedure for the software development; everything was done on ad hoc basis. This adhoc approach led to the ‘software crisis’.Over the last few decades there has been a tremendous growth in informationtechnology and its impact on everyday life. Complex software systems have becomecritical to the operation of many systems in areas such as banking, communications,manufacturing, power generation, and transportation. Progress in computer science andaccumulated experience with industrial production of software have led to the emergenceof software engineering as a separate discipline. The software engineering disciplinehas been defined as "the application of systematic, disciplined, quantifiableapproaches to the development, operation, and maintenance of software." that is, theapplication of engineering to software . ()The computer science discipline concerns with developing large applications.Software engineering covers not only the technical aspects of building software systems,but also management issues, such as directing programming teams, scheduling, andbudgeting.For developing a software product, the development process is divided into differentstages. A convenient way of splitting the whole process is to divide the developmentinto the following five stages:Requirements Analysis & Specification: define the system requirements in detailDesign: specify system architecture and modules in detailCoding: produce source codeTesting: deal with unit testing and system testingMaintenance: fix bugs, enhance features and adapt across platforms.（二）Tell whether the following statements are true(T) or false(F) according to thepassage A.（根据上文的内容判断下列句子的正误）（10分,每题2分）1.During initial days of the development of software, everything was done indiscipline. ( )2.The definition of software engineering is "the application of systematic,disciplined, quantifiable approaches to the development, operation, and maintenanceof software." ( )3. For developing a software product, you need design, coding and testing. ( )4. software engineering is the application of engineering to software .( )5. Software engineering only covers the technical aspects of building software systems.( )Passage BIn order to solve a computational problem, its solution must be specified in terms ofa sequence of computational steps, each of which may be performed by a human or adigital computer . If you want to solve the computational problem with a computer, youshould learn how to program. The task of developing programs for the solution ofcomputational problems is referred to as programming. Computer programming is theprocess of planning and creating a sequence of steps for a computer to follow. Ingeneral, this process will help us resolve a problem, which is either too tedious ordifficult to work out otherwise . So programming is breaking a task down into smallsteps.Programming is sometimes contrasted with coding. Coding generally refers to thewriting of programs for given program specification, while programming includes thetask of preparing the program specification as well as that of writing the program. Thetext of a program is sometimes referred to as code, and lines of program text arereferred to as lines of code, especially in the case of machine-language programs. Theterm coder is used to describe a person engaged exclusively in implementing programspecifications prepared by others.What's actually involved in programming - the actual process of writing programs?Here's a quick overview of the process:· Write a program.· Compile the program.· Run the program.· Debug the program.· Repeat the whole process until the program is finished.(三)、choose the best answer according to the passage B.(根据上文的内容选择正确的答案。
