Unix History–Understand where and how Unix developed

Unix History

Unix Founder  Bell

The UNIX operating system is a set of programs that act as a link between the computer and the user.

  • Unix was originally developed in 1969 by a group of AT&T employees ats, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna.
  • There are various Unix variants available in the market. Solaris Unix, AIX, UP Unix and BSD are few examples. Linux is also a flavour of Unix which is freely available.
  • Several people can use a UNIX computer at the same time; hence UNIX is called a multiuser system.
  • A user can also run multiple programs at the same time; hence UNIX is called multitasking.

Why UNIX?

  • Hardware independence
    • operating system code is written in C language rather than a specific assembly language
    • operating system software can be easily moved from one hardware system to another
    • UNIX applications can be easily moved to other UNIX machines. Porting is usually as simple as transfer of the source and a recompile
  • Productive environment for software development
    • rich set of tools
    • versatile command language
  • UNIX is available at virtually all HPC centers, allowing researchers relative ease in utilizing the facilities at each center.
  • Distributed processing and multi-tasking
