A clean water source, water is not contaminated. To have a reliable power supply, not only to maintain normal lighting,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.IV(Translate the following passage from English into Chinese.A computer system includes a computer, peripheral(外围的)devices, and software.

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.计算机系统包括计算机、外围设备和软件。
计算机英语第二版译文和答案(1—4单元及第9单元)
《计算机英语》参考译文和练习答案目录第一单元 (2)课文A:计算机概览 (2)第二单元 (4)课文A:计算机硬件 (4)第三单元 (7)课文A:操作系统 (7)第四单元 (10)课文A:编程语言 (10)第九单元 (12)课文A:计算机网络 (12)第一单元课文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,然后通过对数值数据进行运算或者对其他形式的信息进行处理来执行该程序。
如果没有计算机的发展,现代的高科技世界是不可能产生的。
在整个社会,不同型号和不同大小的计算机被用于存储和处理各种数据,从政府保密文件、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,计算机无不是必要的工具,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,数字计算机的先驱,是1642年由法国科学家、数学家兼哲学家布莱斯•帕斯卡设计的。
这个装置使用了一系列有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移动轮子,就可以将数字彼此相加。
在17世纪70年代,德国哲学家兼数学家戈特弗里德•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义。
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,英国数学家兼发明家查尔斯•巴比奇,提出了现代数字计算机的原理。

第1 章计算机系统概述数字计算机也称为电子计算机或计算机.它无处不在.很难发现有哪个领域没有使用计算机.在本章中.我们将介绍数字计算机、数据类型、计算机的发展和计算机分类,1 . 1 数字计算机数字计算机是处理各种计算任务的数字系统。
“数字”的意思是计算机中的信息可由具有部分离散值的变量来表示,这些离散值的内部处理是由具有部分离散状态的部件完成的.例如.十进制数字O , l , 2 ,… 9 .即提供了10 个离散值。
第一台电子数字计算机产生于20 世纪40年代末,它主要用于数值计算,那时的离散元素即为数字.为了进行数值计算而产生了数字计算机.实际上.如果只使用两种状态.数字计算机的性能将更可靠。
因为部件的物理约束和人们的逻辑处理需要.所以数字计算机使用具有两种值的离散数据.这种数据称为二进制。
数字计算机使用只有数字O 和l 的二进制数据系统.一个二进制数字称作位.在数字计算机中用一组二进制表示信息。
应用各种编码技术.一组二进制数字不但可以表示二进制数据,而且还可以表示其他离散符号.如十进制数字或字母表中的字母.例如ASCII是用7 位二进制数字表示一个字符。
通过合理使用二进制组合和各种编码技术.可产生用于完成各种类型计算的一系列指令。
与基数为10 的十进制数相比.二进制数的基数为2 .使用了数字O 和1 .与一个二进制数等值的十进制数可以扩展为包含更多位的二进制数.计算机系统是由硬件系统和软件系统组成的,硬件系统由看得见、摸得着的物理设备构成.如磁盘和屏幕。
软件系统是管理计算机的无形“控制”,是运行在计算机中的所有程序,程序是指令的集台,它告诉硬件应该做什么,通常将计算机硬件分为3 个主要部分:输入和输出设备(I/O 设备)、中央处理器(CPU)和存储器。
在第2 章中对硬件部分进行详细介绍.软件可以按其用途分类。
应用软件是为诸如会计、娱乐和工程领域之类的处理任务而设计的,如果玩过计算机游戏或用字处理软件输入入过文件内容.则用户已经具有使用应用软件的体验。

12.1 Multimedia
Vector graphics use mathematical formulas to recreate the original image. In a vector graphic, the dots are not defined by a row-and-column address; rather they are defined by their spatial relationships to one another. Because their dot components are not restricted to a particular row and column, vector graphics can reproduce images more easily, and they generally look better on most video screens and printers. Common vector graphics formats are Encapsulated Postscript (EPS), Windows Meta (WMF), Hewlett-Packard Graphics Language (HPGL), and Macintosh graphics (PICT). 矢量图形用数学公式来重现原始图像。在矢量图形中,点不是用行和列 的地址来定义的;相反,它们是由相互之间的空间关系定义的。因为它 们的组成点不严格限制在特定的行和列上,矢量图形可以更容易地复制 出图像,而且它们在大多数视屏和打印机上看上去效果更好。常见的矢 量图形格式有附录显示格式(EPS)、Windows图元文件格式 (WMF)、惠普图形语言(HPGL)和麦金托什图形文件格式。

Modifications at the physical level are occasionally necessary to improve performance.Logical data independence is the ability to modify the logical schema without causing application programs to be rewritten. Modifications at the logical level are necessary whenever the logical structure of the database is altered (for example, when money-market accounts are added to a banking system).4Chapter 8I.

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 providessome 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.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.计算机系统包括计算机、外围设备和软件。
