Hacking and Cracking

Hacker is a term used by some to mean "a clever programmer" and by others, especially those in popular media, to mean "someone who tries to break into computer systems."
Computer hacking, including the following types of activity:

  • Hacker (programmer subculture), activity within the computer programmer subculture
  • Hacker (computer security), to access computer networks, legally or otherwise
  • Computer crime
  • Phone hacking, the practice of intercepting telephone calls or voicemail messages without the consent of the phone's owner

Crack means to break into a computer system. The term was coined in the mid-80s by hackers who wanted to differentiate themselves from individuals whose sole purpose is to sneak through security systems. Whereas crackers sole aim is to break into secure systems, hackers are more interested in gaining knowledge about computer systems and possibly using this knowledge for playful pranks. Although hackers still argue that there's a big difference between what they do and what crackers do, the mass media has failed to understand the distinction, so the two terms -- hack and crack -- are often used interchangeably.
   Software cracking is the modification of  software to remove or disable features which are considered undesirable by the person cracking the software, usually related to protection methods: (copy protection, protection against the manipulation of software), trial/demo version, serial number, hardware key, date checks, CD check or software annoyances like nag screens and adware.
