great source of information, they use it for communicating with friends, homework and entertainment. Many teenagers know much about computers but their lack of experience can make them forget about the internet dangers and even become victims of on-line crime.

But often the opportunity to get information from the net leads to cheating when pupils just copy someone's papers. Another danger is lack of sleep.
