What is Hacker?Is That White Collar Criminal?

Hacker is the one who dwells upon the security risks of your computer.These guys are the best at what they do.They find the loops with the system and then attack the weaker parts.They can take all your personnal info and use it any where they like. The other side of the whole thing is they are all not bad.If it is not for the good hackers the computers might have not been waht the are today.These good guys helped the software builders to write a simple code and avoid bugs in their software. I heard there is a market there for good hackers and I can tell you one incident wher a friend of mine working for a MNC software company demonstarted to all the guys how their bank account(i.e their salary account) can be hacked to make some payments.This helped everyone in realizing the loops and cover them.
