The computer is the greatest invention of the 20th century. Since the emergence of the first computer in 1946, the computer has been developing rapidly and has changed our life noticeably.

Because of its ability of thinking, memorizing and amazing calculating speed, computers have been widely used in industry, agriculture, business as well as education and tourism. Scientists have been working to solve the most difficult biological problem of decoding human DNA with the help of the computer.

The computer is gradually going into our everyday life. If we don't know how to use the computer, we might find it difficult to get round to sth. Therefore, it's very important for us to keep up with computer technology.
