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.。

According to the mode of processing, computers are either analog or digital. They can be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC, introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.Unit 2 Section A（P34）I．Fill in the blanks with the information given in the text:1．input; output; storage2．Basic Input Output System3．flatbed scanners; hand-held scanners4．LCD-based5．dot-matrix printers; inkjet printers6．disk drives; memory7．Volatile8．serial; parallelII．Translate the following terms or phrases from English into Chinese and vice versa:1．Function key 功能键2．voice recognition module 语音识别模块3．touch-sensitive region 触感区，触摸区4．address bus 地址总线5．flatbed scanner 平板扫描仪6．dot-matrix printer 点阵打印机（针式打印机）7．parallel connection 并行连接8．cathode ray tube 阴极射线管9．video game 电子游戏（港台亦称电玩）10．audio signal 音频信号11．operating system 操作系统12．LCD (liquid crystal display) 液晶显示（器）13．inkjet printer 喷墨打印机14．data bus 数据总线15．serial connection 串行连接16．volatile memory 易失性存储器17．laser printer 激光打印机18．disk drive 磁盘驱动器19．BIOS (Basic Input Output System) 基本输入输出系统20．video display 视频显示器III．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 disk read-only memory. Unlike floppy and hard disks, which use magnetic charges to represent 1s and 0s, optical disks use reflected light. On a CD-ROM disk, 1s and 0s are represented by flat areas and bumpy areas (called “pits”) on its bottom surface. The CD-ROM disk is read by a laser that projects a tiny beam of light on these areas. The amount of reflected light determines whetherthe area represents a 1 or a 0.Like a commercial CD found in music stores, a CD-ROM is a “read-only” disk. Read-only means it cannot be written on or erased by the user. Thus, you as a user have access only to the data imprinted by the publisher.A single CD-ROM disk can store650 megabytes of data. That is equivalent to 451 floppy disks. With that much information on a single disk, the time to retrieve or access the information is very important. An important characteristic of CD-ROM drives is their access rate.Unit 3 Section A（P57）I．Fill in the blanks with the information given in the text:1．artificial; instructions2．low-level; high-level3．low-level4．Machine5．functional; logic6．Statement7．Module8．digitalII．Translate the following terms or phrases from English into Chinese and vice versa:1．storage register 存储寄存器2．function statement 函数语句3．program statement 程序语句4．object-oriented language 面向对象语言5．assembly language 汇编语言6．intermediate language 中间语言，中级语言7．relational language 关系（型）语言8．artificial language 人造语言9．data declaration 数据声明10．SQL 结构化查询语言11．executable program 可执行程序12．program module 程序模块13．conditional statement 条件语句14．assignment statemen t赋值语句15．logic language 逻辑语言16．machine language 机器语言17．procedural language 过程语言18．programming language 程序设计语言19．run a computer program 运行计算机程序20．computer programmer 计算机程序设计员III．Fill in each of the blanks with one of the words given in the following list, making changes if necessary:A programming language is a language used to write instructions for the computer. 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; alongwith 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 create high-quality code in terms of execution speed and storage consumption became an interesting computer science problem in itself.Unit 4 Section A（P81）I．Fill in the blanks with the information given in the text:1．application; operating2．assemblers3．compiler4．interpreter5．Debugger6．Loop7．device driver8．John von NeumannII．Translate the following terms or phrases from English into Chinese and vice versa:1．inference engine 推理机2．system call 系统调用3．compiled language 编译语言4．parallel computing 平行计算5．pattern matching 模式匹配6．free memory 空闲内存7．interpreter program 解释程序8．library routine 库程序9．intermediate program 中间程序，过渡程序10．source file 源文件11．interpreted language 解释（性）语言12．device driver 设备驱动程序13．source program 源程序14．debugging program 调试程序15．object code 目标代码16．application program 应用程序17．utility program 实用程序18．logic program 逻辑程序19．ink cartridge 墨盒20．program storage and execution 程序的存储与执行III．Fill in each of the blanks with one of the words given in the following list, making changes if necessary:A compiler, in computer science, is a computer program that translates source code into object code. Software engineers write source code using high-level programming languages that people can understand. Computers cannot directly execute source code, but need a compiler to translate these instructions into a low-level language called machine code.Compilers collect and reorganize (compile) all the instructions in a given set of source code to produce object code. Object code is often the same as or similar to a computer’s machine code. If the object code is the same as the machine language, the computer can run the program immediately after the compiler produces its translation. If the object code is not in machine language, other programs—such as assemblers, binders (联编程序), linkers (连接程序), and loaders (装入程序)—finish the translation.Most computer languages use different versions of compilers for different types of computers or operating systems, so one language may have different compilers for personal computers (PC) and Apple Macintosh computers. Many different manufacturers often produce versions of the same programming language, so compilers for a language may vary between manufacturers.Unit 7 Section A（P153）I．Fill in the blanks with the information given in the text:1．Telegraph2．dots; dashes3．Media4．point-to-point5．Analog6．Digital7．text-based8．modemII．Translate the following terms or phrases from English into Chinese and vice versa:1．microwave radio 微波无线电2．digital television 数字电视3．DSL 数字用户线路4．analog transmission 模拟传输5．on-screen pointer 屏幕（触摸屏）上的指示（器）6．computer terminal 计算机终端7．radio telephone 无线电话8．cellular telephone 蜂窝电话（移动电话）9．decentralized network 分散的网络10．wire-based internal network 基于普通网线的内部网络11．fiber-optic cable 光缆12．fax machine 传真机13．wireless communications 无线通信14．point-to-point communications 点对点通信15．modulated electrical impulse 调制电脉冲16．communication(s) satellite 通信卫星17．telegraph key 电报电键18．transmission medium 传输媒体19．cordless telephone 无绳电话20．metal conductor 金属导体III．Fill in each of the blanks with one of the words given in the following list, making changes if necessary:Data communications is the process of transmitting and receiving data in an orderly way so the data that arrives at its destination is an accurate duplication 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, the communication is referred to as telecommunications; the prefix “tele” is derived from a Greek word that means “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 data travels 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.Unit 12 Section A（P272）I．Fill in the blanks with the information given in the text:1．employees2．Hackers3．Crackers4．damage; manipulation5．Worm6．software piracy7．access; backup8．PasswordsII．Translate the following terms or phrases from English into Chinese and vice versa:1．encryption program 加密程序2．deletion command 删除命令3．authorized user 授权的用户4．backup copy 备份的副本5．voltage surge 电涌，浪涌电压6．circuit breaker 断路器7．electronic component 电子器件8．data-entry error 数据输入错误9．electronic break-in 电路中断10．power line 电力线，输电线11．detection program 检测程序12．power source 电源13．destructive computer program 破坏性计算机程序14．computer virus 计算机病毒15．software piracy 软件侵权16．hard-disk drive 硬盘驱动器17．virus checker 病毒检查程序18．primary storage 主存储器19．electronic bulletin board 电子公告板20．surge protector 浪涌电压保护器III．Fill in each of the blanks with one of the words given in the following list, making changes if necessary:A virus or other unwelcome surprise can lurk in your computer system for days or months without discovery. A time bomb is a computer program that stays in your system undetected until it is triggered by a certain event in time, such as when the computer system clock reaches a certain date. A time bomb is usually carried by a virus or Trojan horse. For example, the Michelangelo virus contains a time bomb designed to damage files on your hard disk on March 6, the birthday of artist Michelangelo.A logic bomb is a computer program that is triggered by the appearance or disappearance of specific data. For example, suppose a programmer in a large corporation believes that she is on the list of employees to be terminated during the next cost-cutting campaign. Her hostility (敌意) overcomes her ethical (道德的) judgment, and she creates a logic bomb program that checks the payroll (在职人员名单) file every day to make sure her employment status is still active. If the programmer’s status changes to “terminated,” her logic bomb activates a program that destroys data on the computer.A time bomb or logic bomb might do mischief(祸害) in your computer long before the timer goes off. If the bomb contains a virus, it could replicate and spread to other files. Meanwhile, you might send files from your computer to other computers, not knowing that they are infected.。

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:Computers can communicate with other computers through a series of connections and associated hardware called a network. The advantage of a network is that data can be exchanged rapidly, and software and hardware resources, such as hard-disk space or printers, can be shared. Networks also allow remote use of a computer by a user who cannot physically access the computer.One type of network, a local area network (LAN), consists of several PCs or workstations connected to a special computer called a server, often within the same building or office complex. The server stores and manages programs and data. A server often contains all of a networked group’s data and enables LAN workstations or PCs to be set up without largestorage capabilities. In this scenario (方案), each PC may have “local”memory (for example, a hard drive) specific to itself, but the bulk of storage resides on the server. This reduces the cost of the workstation or PC because less expensive computers can be purchased, and it simplifies the maintenance of software because the software resides only on the server rather than on each individual workstation or PC.IV.

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。

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。

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can also be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance , such as UNIVAC (通用自动计算机), introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV. Translate the following passage from English into Chinese: 计算机将变得更加先进，也将变得更加容易使用。

Fill in each of the blanks with one of the words given in the following list, makingchanges if necessary:There are three different types of software maintenance. Firstly, there is maintenance to repair software faults. Coding errors are usually relatively cheap to correct; design errors are more expensive as they may involve rewriting several program components. Requirements errors are the most expensive to repair because of the extensive system redesign that may be necessary. Secondly,there is maintenance to adapt the software to a different operating environment. This type of maintenance is required when some aspect of the system’s environment such as the hardware, the platform operating system or other support software changes. The application system must be modified to adapt it to cope with these environmental changes. And thirdly, there is maintenance to add to or modify the system’s functionality. This type of maintenance is necessary when the system requirements change in response to organizational or business change. The scale of the changes required to the software is often much greater than for the other types of maintenance. In practice, there isn’t a clear-cut distinction between these types of maintenance. When you adapt the system toa new environment, you may add functionality to take advantage of new environmental features.Software faults are often exposed because users use the system in unanticipated ways. Changing the system to accommodate their way of working is the best way to fix these faults.IV. Translate the following passage from English into Chinese:软件过程比较复杂，而且像所有其他的智能和创造性过程一样，依靠人们作出决定和判断。

人邮计算机英语第三版课后习题答案

人邮计算机英语第三版课后习题答案Unit 1 〖Ex. 1〗根据课文内容回答问题(1) A general-purpose computer has four main sections. They are the arithmetic and logic unit (ALU), the control unit, the memory, and the input and output devices, collectively termed I/O. They are interconnected by busses, often made of groups of wires.(2)The control unit is often called a control system or central controller.(3) ● Read the code for the next instruction from the cell indicated by the program counter.● Decode the numerical code for the instruction into a set of commands or signals for each of the other systems.● Increment the program counter so it points to the next instruction.● Read whatever data the instruction requires from cells in memory, or perhaps from an input device. The location of this required data is typically stored within the instruction code.● Provide the necessary data to an ALU or register.● If the instruction requires an ALU or specialized hardware to complete, instruct the hardware to perform the requested operation.● Write the result from the ALU back to a memory location or to a register or perhaps an output device.● Jump back to the first step.(4) The two classes of operations ALU is capable of performing are arithmetic and logic.(5) Logic operations involve Boolean logic: AND, OR, XOR and NOT.(6) A computer's memory can be viewed as a list of cells into which numbers can be placed or read. Each cell has a numbered "address" and can store a single number.(7) The two principal varieties of computer main memory are random access memory or RAM and read-only memory or ROM.(8) In a PC, the specialized program called the BIOS orchestrates loading the computer's operating system from the hard disk drive into RAM whenever the computer is turned on or reset. (9) Software that is stored in ROM is often called firmware because it is notionally more like hardware than software.(10) I/O is the means by which a computer receives information from the outside world and sends results back.〖Ex. 2〗根据下面的英文解释，写出相应的英文词汇(1)input (2) microprocessor (3) program (4) bus (5) hardware (6) memory (7) output (8) cell (9) register (10) address〖Ex. 3〗把下列句子翻译为中文(1) 他进城的目的是买一台新计算机。

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can also be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance , such as UNIVAC (通用自动计算机), introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV. Translate the following passage from English into Chinese: 计算机将变得更加先进，也将变得更加容易使用。
