Computers are becoming more and more important in our daily life. Do you know the history and the changes of computers? A computer was invented in 1946. At that time, the machine was huge.
The computer is a very useful tool in our daily life. For example, it can send some messages to friends by e-mail. What’s more, it can open our eyes to let us know more. There are many computer functions. We can listen to music or play the games on computers. It makes us relax.
It’s hard to imagine what our life would be like if we had no computers in our daily life.
And in my opinion, computers are going to change our life completely in the near future.
