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。

This will serve as a helpful resource for those studying computer science or preparing for any computer-related exams. Please note that the format of the questions and answers will be presented in a clear and organized manner, without the use of section numbers or headings.Question 1:What is the difference between RAM and ROM?Answer:RAM stands for Random Access Memory, whereas ROM stands for Read Only Memory. The main difference between these two is that RAM is a volatile memory that can be read from and written to by the computer, while ROM is non-volatile and its contents are not easily altered.Question 2:What is the purpose of an operating system?Answer:An operating system (OS) is a software that manages computer hardware and software resources and provides common services for computer programs. Its primary purpose is to enable user interaction with the computer and ensure the efficient execution of programs.Briefly explain the concept of object-oriented programming (OOP).Answer:Object-oriented programming is a programming paradigm that organizes software design around objects, which can contain data and code. It focuses on the concepts of encapsulation, inheritance, and polymorphism, allowing for modular and reusable code.Question 4:What is a firewall and what role does it play in computer security?Answer:A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Its main role is to prevent unauthorized access to or from a private network, providing an additional layer of protection against cyber threats.Question 5:What is the difference between HTTP and HTTPS?Answer:HTTP stands for Hypertext Transfer Protocol, while HTTPS stands for Hypertext Transfer Protocol Secure. The main difference between them is that HTTP is not secure and data transmitted using this protocol is not encrypted, making it vulnerable to eavesdropping. In contrast, HTTPS encrypts the data, ensuring secure communication over the internet.Define the term "cloud computing" and explain its advantages.Answer:Cloud computing refers to the delivery of computing services, including storage, servers, software, databases, networking, and more, over the internet. Its advantages include cost savings, scalability, flexibility, remote accessibility, and automatic software updates.Question 7:What is the purpose of a database management system (DBMS)?Answer:A DBMS is a software that allows users to create, manage, and manipulate databases. Its purpose is to provide an interface for interacting with databases, ensuring efficient storage, retrieval, and manipulation of data.Question 8:Explain the concept of artificial intelligence (AI) and provide an example of its application.Answer:Artificial intelligence is a branch of computer science that deals with creating intelligent machines that can perform tasks requiring human-like intelligence. One example of AI application is machine learning algorithms that analyze large datasets to make predictions or identify patterns.Question 9:What are the common programming languages used for web development?Answer:Common programming languages used for web development include HTML, CSS, JavaScript, Python, PHP, and Ruby. These languages are used to create web pages, define their appearance, enable interactivity, and handle server-side processes.Question 10:Define the term "network topology" and describe the four basic types.Answer:Network topology refers to the physical or logical layout of interconnected devices in a computer network. The four basic types are:1. Bus Topology: All devices are connected to a central backbone, calleda bus.2. Star Topology: All devices are connected to a central hub or switch.3. Ring Topology: Devices are connected in a closed loop, forming a ring.4. Mesh Topology: Each device is connected to every other device in the network.Conclusion:In this article, we have presented a collection of computer English exam questions along with their answers.

)(10分, 每空2分)Software Engineering, which means the application of engineering to software, is a method to develop, operate and ________ software. That is, the development of software is on a systematic, _________, quantitive basis. Before starting the development of software, you have to systematically approach the problem. You have to understand the _________ (what the software is supposed to do), carry out the design, do the _________, carry out a rigorous testing and if the software is as per the requirements, release the software to the customer. Subsequently, if the customer wants some changes--refinements or enhancements then the software has to be _________.Passage AThe central processing unit (CPU) is the heart of the computer systems. Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.The CPU comprises the control unit and the arithmetic / logic unit (ALU).The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical (comparison) functions — that is, it adds, subtracts, multiplies, divides, and does comparisons. These comparisons, which are basically “less than”, “greater than”, and “equal to”, can be combined into several common expressions, such as “greater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next.(二)Tell whether the following statements are true(T) or false(F) according to the passage A.(根据上文的内容判断下列句子的正误)(10分,每题2分)1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( )2. The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU and input /output devices are controlled by the control unit of the CPU. ( )3. The CPU comprises the control unit and memory. ( )4. The control unit performs all the arithmetic and logical (comparison) functions5. The central processing unit (CPU) is the heart of the computer systems. ( ) Passage BIn order to solve a computational problem, its solution must be specified in terms of a sequence of computational steps, each of which may be performed by a human or a digital computer . If you want to solve the computational problem with a computer, you should learn how to program. The task of developing programs for the solution ofcomputational problems is referred to as programming. Computer programming is the process of planning and creating a sequence of steps for a computer to follow. In general, this process will help us resolve a problem, which is either too tedious or difficult to work out otherwise . So programming is breaking a task down into small steps.Programming is sometimes contrasted with coding. Coding generally refers to the writing of programs for given program specification, while programming includes the task of preparing the program specification as well as that of writing the program. The text of a program is sometimes referred to as code, and lines of program text are referred to as lines of code, especially in the case of machine-language programs. The term coder is used to describe a person engaged exclusively in implementing program specifications 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。
