Software, on the other hand, refers to the programs and data that are stored on the computer and control its operations. Hardware is tangible and can be seen and touched, while software is intangible and cannot be physically interacted with.(2) What is the purpose of an operating system?An operating system (OS) is a software that manages computer hardware and software resources and provides common services for computer programs. Its purpose is to facilitate the execution of user programs and make it easier for users to interact with the computer. The OS handles tasks such as process management, memory management, file management, and device management.(3) Explain the concept of object-oriented programming.Object-oriented programming (OOP) is a programming paradigm that organizes data and behaviors into objects, which are instances of classes. A class defines the structure and behavior of objects, and objects can interact with each other through methods and attributes. OOP promotes modular and reusable code, as well as encapsulation and abstraction of data. This approach allows for more efficient and easier development, maintenance, and modification of software systems.4. 问答题(1) What are the main programming paradigms?The main programming paradigms include:- Procedural programming: Focuses on procedures or routines that manipulate data.- Object-oriented programming: Focuses on organizing data and behaviors into objects.- Functional programming: Focuses on using mathematical functions and avoids changing state and mutable data.- Logical programming: Focuses on using logical rules and constraints to solve problems.- Imperative programming: Focuses on expressing computation steps explicitly and changing program state.- Event-driven programming: Focuses on handling events and responding to user actions or system events.- Parallel programming: Focuses on executing tasks concurrently to improve performance.(2) What are the differences between HTTP and HTTPS?HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are both protocols used for communication over the internet. The main differences are:- Security: HTTP is not secure and data is transmitted as plain text, making it vulnerable to interception and manipulation. HTTPS encrypts data using SSL/TLS protocols, providing confidentiality and integrity.- Port: HTTP uses port 80 by default, while HTTPS uses port 443.- Certificate: HTTPS requires a digital certificate from a trusted Certificate Authority (CA) to establish a secure connection. HTTP does not require a certificate.- Speed: HTTPS may be slightly slower than HTTP due to the encryption and decryption processes.5. 名词解释(1) Firewall: A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and an untrusted external network, preventing unauthorized access and protecting against malware and other cyber threats.(2) Cache: In computing, a cache is a high-speed data storage layer that stores frequently accessed or recently used data. It serves as a temporary storage to improve data retrieval speed and reduce latency. Caches can be found at different levels in a computer system, such as CPU cache, web browser cache, and DNS cache.(3) Algorithm: An algorithm is a set of step-by-step instructions or rules used to solve a problem or perform a task. It provides a clear and unambiguous method for solving a problem, and it is an essential concept in computer science and programming. Algorithms can be represented using pseudocode, flowcharts, or programming languages.(4) Encryption: Encryption is the process of converting plain text or data into a coded form, known as ciphertext, using an encryption algorithm and a secret key. It ensures the confidentiality and integrity of data by making itunreadable to unauthorized users. Encryption is widely used in data transmission, online banking, and secure communication.(5) Database: A database is an organized collection of structured data stored and accessed electronically. It is designed to efficiently store, retrieve, and manage large volumes of data. Databases are used in various applications, such as e-commerce, customer relationship management (CRM), inventory management, and more.。

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, 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。

每小题2分,共10分)The main tasks of a computer programmer are first, to write programs to solve problems; second, to write them on time as they are needed; and third, to write them clearly by fully documenting them so that other programmers can understand them. The kinds of problems that are tackled(解决)depend on whether the programmer is working for a computer manufacturer(制造商) or user. The former needs such programs as compilers, assemblers, executives, operating systems, and utility routines. These programs are intermediaries(中间者) between the machine and the commercial programs which are written in one of the high-level languages. They areabout the system, and therefore programmers who write them are called system programmers. If the programmer is working for computer users, however, his or her programs may deal with either scientific or commercial problems.51 A computer programmer should undertake () main tasks.A. 1B. 2C. 3D.452 The word they' in Line 2 of this paragraph refers to ().A. programsB. programmersC. tasksD. problems53 () kinds of system programs are mentioned in the paragraph.A. 5B. 6C. less than 5D. more than 654 () is written in one of the high-level languages.A.
