Computers today. Гурьянова В.И. - 19 стр.

it should be recognized that computers are capable of doing repetitive opera-
tions. A computer can perform similar operations thousands of times, without
becoming bored, tired, or even careless. Secondly, computers can process in-
formation at extremely rapid rates. Thirdly, computers may be programmed to
any level of accuracy specified by the programmer. These machines are very ac-
curate and reliable, especially when the number of operations they can perform
every second is considered. Because they are man-made machines, they some-
times malfunction or break down and have to be repaired. However, in most in-
stances when the computer fails, it is due to human error and is not the fault of
the computer at all. In the fourth place, general-purpose computers can be pro-
grammed to solve various types of problems due to their flexibility. One of the
most important reasons why computers are so widely used today is that almost
every big problem can be solved by solving a number of little problems – one
after another. Finally, a computer, unlike a human being, has no intuition. A per-
son may suddenly find the answer to a problem without working out too many
of the details, but a computer can only proceed as it has been programmed to.
