well it depends on what you are trying to say here. If you are talking about causing harm to a computer, the term now-adays it is "Cracking into someones computer or network", and hense forth done by a "Cracker." These little pricks are the guys that you hear passing viruses and malicious scripts all around the net. Though unfortunately "Hacker" and "Cracker" are used incorrectly as synonyms.

I perfer to think of Hackers as Computer security flaw locators, which are employed mostly by companies to find holes and flaws in their network, sometimes paid well, sometimes not as much, but they are truely reverse engineers, as said before; they work from the finished product into the system to expose flaws...

So lets not confuse the two, shall we? :lol:
