计算机系统包括计算机、外围设备和软件。用于处理数据的电动、电子与机械设备称为硬件。除了计算机本身之外，“硬件”这一术语还指被称为外围设备的组件，这些外围设备可扩大计算机的输入、输出和存储能力。计算机硬件本身在本质上并未提供一件特别有用的智能工具。计算机要想变得有用，就需要有称为软件或计算机程序的一套指令，来告诉计算机如何执行一项特定的任务。计算机在以下情况下变得更加有效：与网络中的其他计算机相连接，以使用户能够共享信息
IV．Translate the following passage from English into Chinese.
A computer system includes a computer, peripheral（外围的）devices, and software. The electric, electronic, and mechanical devices used for processing data are referred to as hardware. In addition to the computer itself, the term “hardware” refers to components called peripheral devices that expand the computer’s input, output, and storage capabilities. Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, a computer requires a set of instructions, called software or a computer program, which tells the computer how to perform a particular task. Computers become even more effective when connected to other computers in a network so users can share information.

英语(第三版)第一册课后翻译答案及原文
新视野大学英语（第三版）第一册课后翻译答案及原文Unit 1原文：Socrates was a classical Greek philosopher who is credited wi th laying the fundamentals (基础) of modern Western philosoph y. He is a mysterious figure known chiefly through the accoun ts of later classical writers, especially the writings of his most famous student Plato.Socrates has become well known for his contribution to the field of ethics. His method of teach ing, known as the Socratic Method, by asking and answering qu estions to stimulate critical thinking and to explain ideas r emains a commonly used tool in a wide range of discussions. H e also made important and lasting contributions to the field of epistemology (认识论) and logic, and the influence of his ideas and approach remains a strong foundation for Western ph ilosophy that followed.Socrates was the most colorful figure in the history of ancient philosophy. His fame was widespread in his own time, and his name soon became a household word a lthough he constructed no philosophical system, established n o school, and founded no sect (宗派).翻译：苏格拉底是古希腊哲学家，被誉为现代西方哲学的奠基人。

计算机英语实用教程第三版课后练习题含答案
计算机英语实用教程第三版课后练习题含答案第一章练习题答案1. What is the difference between a CPU and a GPU?A CPU (Central Processing Unit) is a general-purpose processor that performs tasks that require complex arithmetic and logical operations. A GPU (Graphics Processing Unit), on the other hand, is a specialized processor that is designed to handle tasks that involve highly parallelizable computations, such as those required for rendering graphics.2. What is the difference between RAM and ROM?RAM (Random Access Memory) is a type of memory that stores data temporarily while the computer is running. RAM is volatile, meaning that its contents are erased when the computer is turned off. ROM (Read-Only Memory), on the other hand, is a type of memory that stores data permanently, even when the computer is turned off. ROM is non-volatile, meaning that its contents are retned even when there is no power.3. What is the difference between a bit and a byte?A bit is the smallest unit of digital information, represented by a binary digit (0 or 1). A byte, on the other hand, is a unit of digital information that consists of eight bits. Bytes are commonly used to represent characters, such as letters and numbers.4. What is the purpose of an operating system?An operating system (OS) is a software program that manages the resources of a computer, including the CPU, memory, storage, and devices such as printers and displays. The purpose of an operating system is to provide an environment in which applications can run and interact with the hardware without directly accessing the underlying hardware.5. What is the difference between a compiler and an interpreter?A compiler is a program that translates the source code of a program into executable code that can be run on a specific computer platform. The resulting executable code can be run multiple times without the need for recompilation. An interpreter, on the other hand, is a program that reads and executes source code instructions one at a time. Interpreted code is typically slower than compiled code, but does not require the extra step of compilation before it can be run.第二章练习题答案1. What is the difference between a LAN and a WAN?A LAN (Local Area Network) is a network that connects computers and other devices that are located in the same physical location, such as an office building or a home. A WAN (Wide Area Network), on the other hand, is a network that connects computers and other devices that are located in different physical locations, often separated by vast distances.2. What is a router and how does it work?A router is a device that connects two or more networks together and forwards data between them. Routers use routing tables to determine thebest path for data to take between networks, and use protocols such as TCP/IP to communicate with other devices on the network.3. What is the difference between TCP and UDP?TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both protocols used for transmitting data over the internet. TCP is a connection-oriented protocol, which means that it establishes avirtual circuit between two endpoints over which data can be transmitted. TCP uses error correction and flow control to ensure that data arrivesat its destination correctly and in the correct order. UDP, on the other hand, is a connectionless protocol that does not establish a virtual circuit between endpoints. UDP does not provide error correction or flow control, but is often used in situations where speed and simplicity are more important than reliability.4. What is a DNS server?A DNS (Domn Name System) server is a special type of server that translates domn names into IP addresses. When a user enters a domn name into their web browser, the browser sends a request to a DNS server to find the corresponding IP address for that domn name. The DNS serverthen returns the IP address to the browser, which can then connect tothe website.5. What is a firewall and how does it work?A firewall is a security device that is used to protect a networkfrom unauthorized access. Firewalls can be implemented as hardware or software, and typically work by examining incoming and outgoing network traffic and blocking any traffic that does not meet a set of predefinedrules. Firewalls can be configured to block specific types of traffic, such as traffic from certn IP addresses or traffic that uses a certn protocol. Firewalls can also be configured to allow or deny access to specific network resources based on user or device credentials.。
计算机英语（第3版）课文翻译与课后答案
《计算机英语（第3版）》参考译文第一单元：计算机与计算机科学课文A：计算机概览一、引言计算机是一种电子设备，它能接收一套指令或一个程序，然后通过对数字数据进行运算或对其他形式的信息进行处理来执行该程序。
要不是由于计算机的发展，现代的高科技世界是不可能产生的。
不同类型和大小的计算机在整个社会被用于存储和处理各种数据，从保密政府文件、银行交易到私人家庭账目。
计算机通过自动化技术开辟了制造业的新纪元，而且它们也增强了现代通信系统的性能。
在几乎每一个研究和应用技术领域，从构建宇宙模型到产生明天的气象报告，计算机都是必要的工具，并且它们的应用本身就开辟了人们推测的新领域。
数据库服务和计算机网络使各种各样的信息源可供使用。
同样的先进技术也使侵犯个人隐私和商业秘密成为可能。
计算机犯罪已经成为作为现代技术代价组成部分的许多风险之一。
二、历史第一台加法机是法国科学家、数学家和哲学家布莱斯?帕斯卡于1642年设计的，它是数字计算机的先驱。
这个装置使用了一系列带有10个齿的轮子，每个齿代表从0到9的一个数字。
轮子互相连接，从而通过按照正确的齿数向前转动轮子，就可以将数字彼此相加。
17世纪70年代，德国哲学家和数学家戈特弗里德?威廉?莱布尼兹对这台机器进行了改良，设计了一台也能做乘法的机器。
法国发明家约瑟夫―玛丽?雅卡尔，在设计自动织机时，使用了穿孔的薄木板来控制复杂图案的编织。
在19世纪80年代期间，美国统计学家赫尔曼?何勒里斯，想出了使用类似雅卡尔的木板那样的穿孔卡片来处理数据的主意。
通过使用一种将穿孔卡片从电触点上移过的系统，他得以为1890年的美国人口普查汇编统计信息。
1、分析机也是在19世纪，英国数学家和发明家查尔斯?巴比奇，提出了现代数字计算机的原理。
他构想出旨在处理复杂数学题的若干机器，如差分机。
许多历史学家认为，巴比奇及其合伙人，数学家奥古斯塔?埃达?拜伦，是现代数字计算机的真正先驱。
巴比奇的设计之一，分析机，具有现代计算机的许多特征。

Fill in each of the blanks with one of the words given in the following list, makingchanges if necessary:Data communications is the process of transmitting and receiving data in an orderly wayso the data that arrives at its destination is an accurate duplication (复制) of the data that was sent. When data travels a short distance, such as when you send data from your computer to your printer, it is referred to as local communications. When data travels a long distance, thecommunication is referred to as telecommunications; the prefix (前缀) “tele” is derived from aGreek word that mean s “far” or “far off.”The difference between a short distance and a long distance is somewhat arbitrary (武断的). For example, if your computer sends data to a printer in the next room, it is regarded as local communications; if you phone the person in the next room, you are transmitting data over a telecommunications device. However, the same basic communications concepts apply to both local communications and telecommunications.Basic data communications concepts are the building blocks for understanding how datatravels on a communications system. These concepts come in handy (派得上用处) when you install, configure, or upgrade a local area network. In addition, these concepts help you set up modems, fax machines, and cellular data transfers.IV. Translate the following passage from English into Chinese: 个人计算机使用电信来提供传输链路，用于传送音频、视频、文本、软件和多媒体服务。
