|You ppl have a common doubt about hackers and crackers. Now let me explain things clearly(and iam proud to be an hacker)..
Hacker z a one, who likes to explore the work, algorithm, dependency of a Programming/New Tech. It can also be said like, a person who enjoys exploring the details of programmable systems and how to stretch their capabilities. Who enjoys programming rather than just theorizing about programming.
Some of the more famous hackers of lore are:
Steve Jobs and Steve Wozniak - the founders of Apple Computer,
Bill Gates - more of a hacker during his teens than later,
Linus Torvalds - the guy behind linux,
Larry Wall - author of Perl,
Bill Joy and James Gosling from Sun Microsystems,
Dennis Ritchie and Ken Thompson from AT&T,
A cracker is one who breaks into or violates the system integrity of remote machines. Having gained unauthorized access, crackers destroy vital data, deny legitimate users service, or cause problems for their targets.
If wanna say things via KISS(keep it short and sweet):
Hackers build things, crackers break them.
