介绍电脑系统英语文章_电脑的英文介绍

Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. [1] Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.

A computer in a wristwatch.The ability to store and execute programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks so long as time and storage capacity are not considerations. 要求

The Computer

The computer is widely used in all phases of society. In industry, business, education, medicine, nearly all walks of life, computers have made their appearance, providing great speed and accuracy for our work. Computers have been used in the home, offices, laboratories and research institutions, functioning as the most efficient and versatile instruments for calculating, sorting, filing, recording and distributing. 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.

作文的内容千变万化，这就要求我们丰富自己的知识，特别是各行业的最新动态。只有这样，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
