What is Hacking ?

1.originally, someone who makes furniture with an axe. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users,
who prefer to learn only the minimum necessary.

2. One whoprograms enthusiastically (even obsessively) or who enjoys programming
rather than just theorizing about programming.

3. A person capable of appreciating hack value.

4. A person who is good at programming(quickly).

5. An expert at a particular program,
or one who frequently does work using it or on it; as in ‘a
Unix hacker.’ (Definitions 1 through 5 are correlated, and people
who fit them congregate.)

6. An expert or enthusiast of any kind.
One might be an astronomy hacker, for example. 

7. One whoenjoys the intellectual challenge of creatively overcoming or circumventing
limitations.

8. [deprecated] A malicious meddler who
tries to discover sensitive information by poking around. Hence
‘password hacker,’ ‘network hacker.’ The correct term for this
sense is cracker.

Cracker
One who breaks security on a system. Coined ca. 1985 by hackers
in defense against journalistic misuse of hacker (q.v., sense 8). An
earlier attempt to establish ‘worm’ in this sense around 1981–82
on Usenet was largely a failure.

Use of both these neologisms reflects a strong revulsion against
the theft and vandalism perpetrated by cracking rings. While it is
expected that any real hacker will have done some playful cracking
and knows many of the basic techniques, anyone past larval stage
is expected to have outgrown the desire to do so except for immediate,
benign, practical reasons (for example, if it’s necessary to get
around some security in order to get some work done).
Thus, there is far less overlap between hackerdom and crackerdom
than the mundane reader misled by sensationalistic journalism
might expect. Crackers tend to gather in small, tight-knit,
very secretive groups that have little overlap with the huge, open
poly-culture this lexicon describes; though crackers often like to
describe themselves as hackers, most true hackers consider them a
separate and lower form of life.

It’s clear that the term cracker is absolutely meant to be derogatory. One
shouldn’t take the tone too seriously though, as The Jargon File is done with a
sense of humor, and the above is said with a smile. As we can see from the
above, illegal or perhaps immoral activity is viewed with disdain by the “true
hackers,” whomever they may be. It also makes reference to cracker being a
possible intermediate step to hacker, perhaps something to be overcome.


Script Kiddie

The term script kiddie has come into vogue in recent years. The term refers to
crackers who use scripts and programs written by others to perform their intrusions.
If one is labeled a “script kiddie,” then he or she is assumed to be incapable
of producing his or her own tools and exploits, and lacks proper
understanding of exactly how the tools he or she uses work. As will be apparent
by the end of this chapter, skill and knowledge (and secondarily, ethics) are the
essential ingredients to achieving status in the minds of hackers. By definition,
a script kiddie has no skills, no knowledge, and no ethics.


Phreak

A phreak is a hacker variant, or rather, a specific species of hacker. Phreak is
short for phone phreak (freak spelled with a ph, like phone is). Phreaks are
hackers with an interest in telephones and telephone systems. Naturally, there
has been at times a tremendous amount of overlap between traditional hacker
roles and phreaks.


White Hat/Black Hat/Gray Hat

White Hat Hacker:
White Hat hackers are good guys who does the hacking for defensing.  They probably work an organization for providing security.


Black Hat Hacker
Black hat hackers are bad guys(the malicious hackers or crackers).  They usually steal the other bank information and steal the money.
They use their skills for illegal purposes.
They are creators of viruses,malware,spyware.
They will destroy your pc.


Gray Hat Hackers

Grey hats are hackers who may work offensively or defensively, depending on the situation.
This is the dividing line between hacker and cracker. Both are powerful forces on the Internet,
and both will remain permanently. And some individuals qualify for both categories. The
existence of such individuals further clouds the division between these two groups of people.
In addition to these groups, there are self-proclaimed ethical hackers, who are interested in
hacker tools mostly from a curiosity standpoint. They may want to highlight security problems
in a system or educate victims so they secure their systems properly. These hackers are
doing their “victims” a favor. For instance, if a weakness is discovered in a service offered by
an investment bank, the hacker is doing the bank a favor by giving the bank a chance to rectify
the vulnerability.
