There is no doubt that computers have brought people more convenient and easier life. Although at the same time we acknowledge that computer sometimes bring people into trouble, there is nothing perfect. I strongly agree that computer is a wonderful invention and have totally changed people's life.   When mentioning the advantage of computer, i think almost everyone has his own words. We use computers everyday and we always use them to search information which we need. By this way, we avoid reading a great deal of books to find what we want. Reading book is always good for us, but to some extent, for example, when we need some information immediately, i think computer is the best chose. We just need to enter some words and can get the results. What is more, computers help to maintain some relationships. By using QQ,msn,or many other kinds of ways, we can contact friends frequently. What is more, we can use online telephone or video to keep in touch with friends who are far away. Today, so many children choose to go abroad to gain further education. All these ways help to reduce the worry and missing of parents. Of course, we cannot forget those wonderful movies downloaded from the computers, so we can enjoy the films free. And these movies or music have enrich our life and make me feel relax.      However, just like what i said before, nothing can be perfect. When we enjoy the convenience brought by computers, at the same time, we should shoulder some risks.Some people lost their way while using computers. They addict to the computer and play games too much. They even do not want to do anything expect those games. What is more, according to the report of medium, we know almost everyday the private information leakage is happening. And it is own to computers. Hackers uses virus to attack computers in order to steal some important information.     In brief, computers bring us convenience and easier life, but we should use it in correct way.
