UNIX is derived from the word UNICS - Uniplexed Information and Computing System. It's a computer operating system originally developed by AT&T employees at Bell Labs including Ken Thompson, Dennis Rithchie, and Douglas Mcllroy. Over the years, several Unix like operating system such as Linux, Mac OS X have been encountered.

Unix is an operating system widely used in both servers and work stations. It is more useful at server space than at client space. It is considered to be very reliable and secure. The various components of the Unix operating system are

  • Kernel - Handles memory management, system calls, etc.
  • Development Environment - Includes libraries, compilers and assemblers
  • Commands - Contains the executable commands
  • Documentation - Contains the manuals and documents for various commands

Though the earlier version did not have a Graphical User Interface (GUI), the later versions even included the GUI component.

Later, a GNU Project was announced to create a free Unix like system. A compatible Kernel was successfully developed called Linux. Examples of these Linux based Operating Systems are Fedora, SUSE, Mandrake.
