Пояснення до тексту

general-purpose computers – універсальні комп’ютери

special–purpose computers – комп’ютери для спеціальних цілей

Computers in our life

1. A computer is really a very specific kind of a counting machine. It can do arithmetic problems faster than any person alive. By means of electric processes it can find the answer to a very difficult and complicated problem in a few seconds.

2. A computer can "remember" information you give it. It keeps the information in its "memory" until it is needed.

3. There are different kinds of computers. Some can do only one job. There are special-purpose computers. Each specific problem requires a specific computer. One kind of computer can help us build a spaceship, another kind can help us navigate it. A special-purpose computer is built for this purpose alone and cannot do anything else.

4. But there are some computers that can do many different jobs. They are called the general-purpose computers. There are the big "brains" that solve the most difficult problems of science.

5. We used to think of a computer as a large machine that took up a whole room. But today computers are becoming smaller and smaller. Though these small devices are called microcomputers or minicomputers, they are still true computers. There are several advantages in making computers as small as one can. Sometimes weight is particularly important. A modern plane carries many heavy electronic apparatus. If it is possible to make any of them smaller, it can carry a bigger weight. But weight is not the only factor. The smaller the computer, the faster in can work. The signals go to and for at a very high but almost constant speed.
