I think using a computer is has many benefits.although it also has its downside. it helps many people. Provide a big store of information: provide popular search engines such as: google.com, coccoc.com, etc.Connects many people all over the world: keeping in touch with your friends by facebook, chatting, e-mail messages, forum,zalo,....Help your studying a lot: seeking document, online teaching & learning, ... Provide entertainment: playing computer games, listening to music, reading book .But it also has its harmful.The waste of time: take whole day in front of computer screen.Harmful to our health: short-sighted, headache, backache, obesity. learn bad things, get cheated by social networks.
