Computer have improved our lives while others think computers have caused problems.in my opinion I think computer does have more positive effects towards our lives than its negative sides.
First, we can keep in touch more closely with the helpof computer. For example, by using Emails or MSN, I can leave messages to my friends in the United States no matter when. But before computer was invented, onehave to wait nearly several months to get a letter from friends abroad.
Second, with computer, we can get information from all over the world easier and moreconvenient.
