People like scientists, teachers, writers and even students use computers to do a lot of work. But more than 30 years ago, computers couldnt do much. They were very big and expensive. Very fewer people were interested in them and knew how to use them. Today computers are smaller and less expensive. Because they can do lots of work, many people like to use them. Some people even have them at home. Computers have become very important because they can work faster than men and they make fewer mistakes. Computers can help people do a lot of work.
