Automation playing an important role in great advances in technology is a well known fact. Automation, properly coordinated with other phases of technology, can substantially contribute to high productive efficiency. Mechanization of production operations and their automation is one of the most important problems.
If there were no computers, there would be no advanced automation, computer science is an exciting field of study and research. Computer science being a broad discipline, it coveres logic design, the theory of computation, numerical analysis, programming and computer application.
There are different kinds of computers. Some do only one job. These are special-purpose computers. But there are some computers that can do many different jobs. They are called general-purpose computers. These are the "big brains" that solve the most difficult problems of science. They answer questions about rockets and planes bridges and ships long before these things are even built.
Today there are computers small enough to be carried In one's pocket or about the size of a typewriter. These new computers are called personal computers. Computers are the most efficient servants man has ever had and there is no limit for their application in improving our lives and saving time for leisure.
Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complicated mathematical problems or put thousands of unrelated facts in order. As computers work accurately and at high speeds, they save research workers years of bard work. This whole process, by which machines an be used to work for us, is called automation. Automation will have important social consequences.
