The United1 States is not the only country affected2 by the“computer revolution”,All the major countries of the world have computers ,and the developing3 countries have also realized that computers play a big part in their economic development.
Usually what one sees is a machine that looks like a typewriter ;it is called a computer terminal(终端)But computers are also used in unseen ways For example they determine how much tine there should be between traffic signals4 to prevent traffic problems and to keep millions of cars moving in an orderly5 flow When you buy a car ,a factory process (过程)that is controlled by a computer enables7 you to obtain8 a car with your own choice of colours and special features (特征)in just a few weeks’ time In medical laboratories9 ,com-puters have reduced the mistakes in testing ,and they have saved doctors’ countless10 hours of work Before long ,medical histories of all Americans will be kept in computer “banks”.If a person becomes ill far from his home ,local doctors will be able to get his medical record immediately ,In science the computer has performed in minutes experiments which would have required thousands of hours of work by human hands and minds.
Most experts agree that computers are necessary to solve the problems of increasing population ,city living ,and public affairs Without computers, the jobs of solving these problems would require millions of workers to do tons of paperwork Before any computer can work on any problem, it must be told what to do Someone must program the computer ,step―by―step. At first this was done by having the programmer write out his instructions in the form of numbers which would be“understood”by the machine ,Within a short time, attempts were made to perform a system that would enable6 humans to communicate programmer could use words that had meanings for him ,and another program in the ma-chine would translate the words into the computer’s number system.
Without special training ,in is impossible to under stand exactly how a computer does int work however ,many people without scientific training use computers in their daily lives .In some American schools for example young children are being taught by comput-ers for part of the school day.
The use of computers in school has worried some Americans There are those who fear is will remove human element(成分)from teacher-student relationships .On the other hand there are educators who consider computer program a valuable means11 of freeing teachers from the more boring and tiring tasks ,thus enabling12 them to spend more time with a single student.
In education ,as in business and industry science and medicine ,computers play an important part in almost every type of operation the future will bring major advances in computer technology ,which will aid man in his efforts to improve the world.
