Computers can process the huge amount of data, and we can listen to music or see pictures. Besides, we can use the Internet with it and get a large amount of information, and computers hold it. When we do businesslike tasks, write reports and send e-mails, computers are especially useful for us. I think typed reports give others a preferable impression, and typing is much faster than handwriting.
However, there are also weak points. The display of a computer makes our eyes tired. I wear contact lenses, so I am liable to feel "dry eyes". When there is something wrong or a computer virus with a computer, it will not work properly. We will feel so annoyed. When we use the Internet, there are a lot of dangers of leaks of private information and bad sites. Using computers is very convenient for us, but we must think of the various risks.
