III．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 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.

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 whether the 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 store 650 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.

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; 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 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）

1．application; operating
2．assemblers

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.

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.

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.
计算机英语第三版课文翻译
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。它有一个以一叠穿孔卡片的形式存在的输入流、一个保存 数据的“仓库”、一个进行算术运算的“工厂”和一个产生永久性纪录的打印机。巴比奇未 能将这个想法付诸实践，尽管在那个时代它在技术上很可能是可行的。 2、早期的计算机 模拟计算机是19世纪末开始制造的。早期型号是靠转动的轴和齿轮来进行计算的。用任 何其他方法都难以计算的方程近似数值，可以用这样的机器来求得。开尔文勋爵制造了一台 机械潮汐预报器，这实际上就是一台专用模拟计算机。第一次和第二次世界大战期间，机械 模拟计算系统，以及后来的电动模拟计算系统，在潜艇上被用作鱼雷航线预测器，在飞机上 被用作轰炸瞄准具的控制器。有人还设计了另一个系统，用于预测密西西比河流域春天的洪 水。 3、电子计算机 第二次世界大战期间，以伦敦北面的布莱切利公园为工作地点的一组科学家和数学家， 制造了最早的全电子数字计算机之一：“巨人”。到1943年12月，这个包含了1500个真空管 的“巨人”开始运转了。它被以艾伦.图灵为首的小组用于破译德国用恩尼格码加密的无线 电报，他们的尝试大部分是成功的。 除此而外，在美国，约翰.阿塔纳索夫和克利福德.贝里早在1939年就在艾奥瓦州立学院
