We build computer to solve problems.Early computer solved mathematical and engineering problems，and later computers emphasized information processing for business applications.T- oday，computers also control machines as diverse as automobile engines，robots，and microwave ovens. A computer system solves a problem from any of these domains by accepting input，processing it，and producing output. Fig. 1-1 illustrates the function of a computer system. Computer systems consist of hardware and software. Hardware is the physical part of the system. Once designed，hardware is difficult and expensive to change. Software is the set of programs that instruct the hardware and is easier to modify than hardware. Computers are valuable because they are general-purpose machines that can solve many different kinds of problems，as opposed to special-purpose machines that can each solve only one kind of problem. Different problems can be solved with the same hardware by supplying the system with a different set of instructions.that is，with different software. undefined Fan译: 计算机组成原理 Ji算机硬件 人们为解决问题而制造计算机。Zao期的计算机解决的是数学和工程问题，后Lai计算机着重解决商业应用中的信息处理问题。如今，Ji算机还用来控制如汽车发动机、机器人He微波炉等各式各样的机器。计算机系统解决上Shu这些领域中的任何一个问题都是通过接收输入、Chu理问题和生成输出来实现的。图1-1Shuo明了计算机系统的功能。 计算机系Tong由硬件和软件组成。硬件是系统的物理部Fen。硬件一旦设计完毕，要修改是困难的，Bing且花费也大。软件是指挥硬件的程序集合，Bi硬件容易修改。计算机之所以有用，是Yin为它们能解决很多不同类型的问题，是通用De机器。相对而言，每种专用机只能解决一类问题。Tong过为系统配备不同的指令系统，也就是配备Bu同的软件，能用同一硬件去解决不同的问题。
The computer is a product of advanced civilization and its invention, according to some people, signals the advent of a Second Industrial Revolution. Formerly a bulky machine that demanded much space, the computer is now becoming smaller and smaller and scientists have made it more sophisticated and accordingly more useful. As is generally known, the computer can do a wide range of work, including complex computation and analyses. People now also use it as a teaching aid in designing. An infinite variety of software can be put into the computer, which explains why it is so powerful. There is, however, one thing which we should bear in mind: that the computer cannot think but man can. So there need not be any fear that someday the computer will control us and all we should expect is try our best to bring it to perfection. A computer age is not a pipe dream and there will come a day when most of our needs can be met by this wonderful machine.

Computers are indispensable to modern civilization. Without computers, our life and our society will undoubtedly suffer a big regression. During the past five decades the computer has been rapidly advanced. Ever since the computer came into being, it has experienced the development of several generations, which are based respectively on vacuum tube, transistor and integrated circuit. Early computers were of great size, and had no match for the latest electronic computers in speed and accuracy. The Latter is capable of processing the most complicated information and reaching solution to problems in a fraction of time. At present, efforts are being made not only to bring the hardware to perfection, but also to improve the quality of the software. Zuo文的内容千变万化，这就要求我们丰富自己的Zhi识，特别是各行业的最新动态。只有这Yang，才能自如地处理各种题材和内容。 Computers must be instructed and programmed by people. In spite of the remarkable skill of the computer, men can never become its slave. Computers are not creative. They work according to men's instructions. So the development of computers and their use will depend upon the ingenuity of men. Although there are times when computers seem to operate like a mechanical “brain”,their achievements are not comparable to what the minds of men are able to do Gei分吧
