What has computer science brought us? It was in the computer class of the college that I caught the first sight of computers. At that time we still learned the commands of DOS and couldn't use windows. It was fashionable to surf the internet and chat in the public chatting room. I still remember one of my roommates had her first cyber love with a young man from Shanghai. It's amazing that computer science develops so fast. Computers have become a must in our daily life and the internet has changed the way we live and work. With the popularity of computers and the development of the internet ,we have already been in an age of information. We are able to obtain the latest news at home and abroad. The status of traditional media is challenged. People no longer rely on the traditional media to know about the world.The world becomes smaller and it becomes easier for people to communicate. Letters have been replaced by emails. Chatting tools like MSN, skype, qq. and weichat are favored by people. It's convenient for people to keep in touch with each other. Yesterday when I was watching a tv play, I couldn't thinking if there were internet at the war time then the communist members wouldn't risk their lives to send telegraphs. Nowadays people can make many things accomplished through the internet ,thus leading to the rise of freelancing. Internet has made it possible to work at home. People spend most of their leisure time online, shopping, chatting, reading, playing games etc. People spend less time with their family , relatives and friends. One weibo article is very famous ,which is called daddy, if you don't accompany me I will grow up. It illustrates we are addicted to the internet so much that we ignore those around us. Internet , to some degree , hinder people's normal work and study. The key is how we should treat the internet and how we use it in an appropriate way.
