Nowadays almost everyone in the world has come into contact with computers. A large part of them have used the international computer network known as the Internet - one of mankind's greatest inventions - which has become an important part of human life. I think using the internet has more advantages but disadvantages. First of all, the internet benefits us in many ways. It gives us a lot of information from all over the world. It keeps us aware of what is happening on earth and keeps us updated with the latest news. In addition, the internet also helps us to expand our social network with many friends in all countries around the world. Through some programs like Facebook, instagram, Messenger, etc., we have the opportunity to make friends and talk to many people. Moreover, it entertains us. Sometimes we can spend time listening to music or watching movies on some websites. However, the internet also causes us many problems. The first thing is our health. Some people spend too much time searching and playing on the internet, which is not good for their brain and eyes. Next, it also prevents us from participating in certain activities such as reading or going out with friends. In addition, some online programs have some bad content such as violence, which is not good for the spiritual life of young people. In short, everything has its two sides, so does the Internet. Therefore, it is essential that we use it for the right purpose.
