Unix (officially trademarked as UNIX® - the documentation switched from using 'UNIX' to 'Unix' as of V7) is a computer operating system originally developed in the 1970s by a group of AT&T employees at Bell Labs including Ken Thompson, Dennis Ritchie and Douglas McIlroy.

Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations. A number of clones of Unix, which share the interfaces, and 'look and feel', but no code, have also been produced.

CSRG releases

Meanwhile the Computer Systems Research Group‎ kept on releasing newer BSD UNIX's derived from 32v. Descended from there are several popular versions:

  • FreeBSD focuses on providing a system geared towards a single user.
  • NetBSD will run on a variety of 32-bit older systems from the VAX to the Amiga.
  • OpenBSD derived from the NetBSD project will run on all kinds of systems.
