Computer in the classroom.Good and bad things about it.

Using computer in  classroom is convinient and very useful. When we need more information about something  we can search on internet  quickly. We can learn English online, listen to conversations, lessons and pronunciation. There are a lot of advantages to use computer in classroom but the problem is sometime students use internet for chatting with friends or playing games that make students not to pay attention to teacher and lesson. That is why schools don't have computers in classroom. Also if you use computer for a longer period it will make your eyes and back painful.
