Роль автоматизации в технологии

There are different kinds of computers. Some do only one job over and over again. There are special-purpose computers. One such computer automatically controls the movement of anti-aircraft canon. It was built for this purpose alone, and cannot do anything else. But there are some computers that can do many different jobs. They are called general-purpose computers. They answer question about rockets and planes, bridges and ships long before these things are even built.
