White-hat (hacking for the enjoyment of exploration)
Black-hat (hacking to find exploits and system weaknesses, see cracker)
and Grey-hat (someone who is a little of both)
Hackers are self-motivated, and learn through experimentation and persistence, as opposed to through "traditional" means.
Computer hackers do not completely fit this definition. Due to the high artificiality of computer technology itself, computer hackers must be highly knowledgable before they can implement their first successful "hack." For them, "hacks" are the product of brilliant insight and thorough investigation, rather than the talent and natural law that go with hacking in more humanity-driven fields, such as entertainment or sports.
Chess masters have a similar level of mental discpline, although many hackers tend to lack the attention span necessary to be good at chess :')
Many people would tend to disagree, but then again many people are not skillful enough to be called a "hacker."
Hackers are not limited to computer hacking.
Commentary: The movies "Tron" (1982) and "War Games" (1983) significantly influenced the common use of "hacker" (by non-hackers) in reference to computer hackers. The widespread use of the Internet beginning around 1993 made millions of unwitting parents concerned that their adolescent child was turning into a hacker. Some of the twit kids even believed it themselves. Please see reference to "lacker" for a more appropriate name for these individuals.
Of the 80s/90s version, there were three primary denominations:
The casual Hacker-hacks to learn information for his own curiosity.
The White Hat Hacker-hunts down and destroys malicious code.
The Black Hat Hacker-designs and releases malicious code;gathers dangerous information;brings down sensative systems.
"The hackers have managed to find their way into the system."
"The hackers are getting on my nerves."
