计算机英语(第3版)课文翻译和课后答案
《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。

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.。

It lets the programmer express data processing in a symbolic manner without regard to machine-specific details.The difficulty of writing programs in the machine language of 0s and 1s led first to the development of assembly language, which allows programmers to use mnemonics for instructions and symbols for variables. Such programs are then translated by a program known as an assembler into the binary encoding used by the computer. Other pieces of system software known as linking loaders combine pieces of assembled code and load them into the machine’s main memory unit, where they are then ready for execution. The concept of linking separate pieces of code was important, since it allowed “libraries” of programs to be built up to carry out common tasks—a first step toward the increasingly emphasized notion of software reuse. Assembly language was found to be sufficiently inconvenient that higher-level languages (closer to natural languages) were invented in the 1950s for easier, faster programming; along with them came the need for compilers, programs that translate high-level language programs into machine code. As programming languages became more powerful and abstract, building efficient compilers that createhigh-quality code in terms of execution speed and storage consumption became an interesting computer science problem in itself.IV．Translate the following passage from English into Chinese.One especially powerful feature of OOP (object-oriented programming) languages is a property which is known as inheritance. Inheritance allows an object to take on the characteristics and functions of other objects to which it is functionally connected. Programmers connect objects by grouping them together in different classes and by grouping the classes into hierarchies. These classes and hierarchies allow programmers to define the characteristics and functions of objects without needing to repeat source code, the coded instructions in a program. Thus, using OOP languages can greatly reduce the time it takes for a programmer to write an application, and also reduce the size of the program. OOP languages are flexible and adaptable, so programs or parts of programs can be used for more than one task. Programs written with OOP languages are generally shorter in length and contain fewer bugs (缺陷), ormistakes, than those written with non-OOP languages.面向对象程序设计语言的一个特别强大的功能，是称为继承的特性。

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:CD-ROM stands for compact disc read-only memory. Unlike floppy and hard disks, which use magnetic charges to represent 1s and 0s, optical discs use reflected light. On aCD-ROM disc, 1s and 0s are represented by flat areas and bumpy (高低不平的) areas (called“pits”) on its bottom surface. The CD-ROM disc is read by a laser that projects a tiny beam oflight on these areas. The amount of reflected light determines whether the area represents a 1or a 0.Like a commercial CD found in music stores, a CD-ROM is a “read-only” disc.Read-only means it cannot be written on or erased by the user. Thus, you as a user haveaccess only to the data imprinted (压印) by the publisher.A single CD-ROM disc can store 650 megabytes (兆字节) of data. That is equivalent to451 floppy disks. With that much information on a single disc, the time to retrieve or accessthe information is very important. An important characteristic of CD-ROM drives is theiraccess rate.IV.
