A computer is a machine with a good memory, and its memory is better than man’s.
Early computers were big and heavy. But they could only do very simple things. Today’s computers are much smaller and lighter, however they can do work better and faster than the early ones. We can use computers to play games, do word processing and write computer programs. Computers have become more and more popular. They have been a very important part in people’s life and work. Do you often use computers in your study?
