computers are both boon and bane. many people now a days think that computer is totally a bane, I don't agree with them because many students work on system for getting more knowledge from it. but few students and people use computers to hack all the bank accounts and take away the money from those accounts which would again become a bane. but really if use computers in an good way know then they are really good for every one but if use it in an bad way I would show it's real colors. so I conclude that computer is both boon and bane. 

hope so my answer is useful..........^_^  !!!
