What is the term Hacker mean's?

HACKER:-
In common usage, a hacker is a person who breaks into computers, usually by gaining access to administrative controls.
The subculture that has evolved around hackers is often referred to as the computer underground. Proponents claim to be motivated by artistic and political ends, and are often unconcerned about the use of illegal means to achieve them.
Other uses of the word hacker exist that are not related to computer security (computer programmer and home computer hobbyists), but these are rarely used by the mainstream media.
Hacking developed alongside "Phone Phreaking", a term referred to exploration of the phone network without authorization, and there has often been overlap between both technology and participants. Bruce Sterling traces part of the roots of the computer underground to the Yippies, a 1960s counterculture movement which published the Technological Assistance Program (TAP) newsletter. [3]. Other sources of early 70s hacker culture can be traced towards more beneficial forms of hacking, including MIT labs or the homebrew club, which later resulted in such things as early personal computers or the open source movement.
Hacker groups:-
The computer underground is supported by regular real-world gatherings called hacker conventions or "hacker cons". These have drawn more people every year including SummerCon (Summer), DEF CON, HoHoCon (Christmas), and H.O.P.E..[citation needed] They have helped expand the definition and solidify the importance of the computer underground.
Hacker attitudes:-
Several subgroups of the computer underground with different attitudes and aims use different terms to demarcate themselves from each other, or try to exclude some specific group with which they do not agree. Eric S. Raymond advocates that members of the computer underground should be called crackers. Yet, those people see themselves as hackers and even try to include the views of Raymond in what they see as one wider hacker culture, a view harshly rejected by Raymond himself. Instead of a hacker – cracker dichotomy, they give more emphasis to a spectrum of different categories, such as white hat (ethical hacking), grey hat, black hat and script kiddie. In contrast to Raymond, they usually reserve the term cracker to refer to black hat hackers, or more generally hackers with unlawful intentions.

What is the term HACKING means?

Hack:-
Hack has several related meanings in the technology and computer science fields. It may refer to a clever or quick fix to a computer program problem, or to what may be perceived to be a clumsy or inelegant (but usually relatively quick) solution to a problem. The term is also used to refer to a modification of a program or device to give the user access to features that were otherwise unavailable, such as DIY circuit bending.
Origin of term:-
The term was used by mathematician John Nash as a putdown. When he become a C.L.E Moore Instructor at Massachusetts Institute of Technology (MIT) in 1951, he brought this putdown with him.[1]

The term achieved widespread use in the 1960s and its meaning then evolved to a quick, elaborate and/or bodged solution students devised for a technical obstacle; it was used with hacker, meaning one who discovers and implements a hack. The word itself comes from the German word meaning "someone who makes furniture with an axe",[2] implying a lack of finesse in a "hack"; it is believed by many in the hacking community that the reason for this is because programs too large to run on the limited computer resources of the time had portions "chopped" or "hacked" out in order to be reduced to a more reasonable size.
See: MIT hacks
Over time, the meaning of the word there was expanded, perhaps through contact with the amateur radio community. It came to mean either a kludge, or the opposite of a kludge, as in a clever or elegant solution to a difficult problem. In the term "hack value" it also acquired a meaning of anything that was simultaneously fun and clever.
The initial hacker community at MIT, particularly those associated with the Tech Model Railroad Club, applied this pre-existing local slang to computer programming, producing the variant which first came into common use outside MIT.
History:-
The term "hack" was first used by US university computing center staff in the mid-1960s. The context determined whether the complimentary or derogatory meanings were implied. Phrases such as "ugly hack" or "quick hack" generally referred to the latter meaning; phrases such as "cool hack" or "neat hack", to the former. In modern computer programming, a "hack" can refer to a solution or method which functions correctly but which is "ugly" in its concept, which works outside the accepted structures and norms of the environment, or which is not easily extendable or maintainable (see kludge). The programmer keeps beating on it until a solution is found. The jargon used by hackers is called "Hackish" (see the Jargon file). This should not be confused with "1337" or "leetspeak."

In a similar vein, a "hack" may refer to works outside of computer programming. For example, a math hack means a clever solution to a mathematical problem. The GNU General Public License has been described as[who?] a copyright hack because it cleverly uses the copyright laws for a purpose the lawmakers did not foresee. All of these uses now also seem to be spreading beyond MIT as well.
On many internet websites and in everyday language the word "hack" can be slang for "copy", "imitation" or "rip-off."
A DIY musician probes the circuit board of a synthesizer for "bends" using a jeweler's screwdriver and alligator clips.
The term has since acquired an additional and now more common meaning, since approximately the 1980s; this more modern definition was initially associated with crackers. This growing use of the term "hack" is to refer to a program that (sometimes illegally) modifies another program, often a computer game, giving the user access to features otherwise inaccessible to them. As an example of this use, for Palm OS users (until the 4th iteration of this operating system), a "hack" refers to an extension of the operating system which provides additional functionality. The general media also uses this term to describe the act of illegally breaking into a computer, but this meaning is disputed.
The term is additionally used by electronics hobbyists to refer to simple modifications to electronic hardware such as a graphing calculators, video game consoles, electronic musical keyboards or other device (see CueCat for a notorious example) to expose or add functionality to a device that was unintended for use by end users by the company who created it. A number of techno musicians have modified 1980s-era Casio SK-1 sampling keyboards to create unusual sounds by doing circuit bending: connecting wires to different leads of the integrated circuit chips. The results of these DIY experiments range from opening up previously inaccessible features that were part of the chip design to producing the strange, disharmonic digital tones that became part of the techno music style. Companies take different attitudes towards such practices, ranging from open acceptance (such as Texas Instruments for its graphing calculators and Lego for its Lego Mindstorms robotics gear) to outright hostility (such as Microsoft's attempts to lock out Xbox hackers or the DRM routines on Blu-ray Disc players designed to sabotage compromised players).
