A Few Words
History of UNIX
- 1969: Developed at AT&T; Bell Labs in Murray Hill, New Jersey, one of the largest research facilities in the world. Created in an environment when most computer jobs were fed into a batch system.
Developed by researchers who needed a set of computing tools to help them with their projects and their collaborators. Allowed a group of people working together on a project to share selected data and programs.
- 1975: AT&T; makes UNIX widely available – offered to educational institutions at minimal cost. Becomes popular with university computer science programs. AT&T; distributes standard versions in source form: Version 6 (1975), Version 7 (1978), System III (1981).
- 1984 to date: University of California, Berkeley adds major enhancements, creates Berkeley Standard Distribution (BSD)
- 1984 to date: Many Berkeley features incorporated into new AT&T; version: System V
- UNIX has become the operating system of choice for engineering and scientific workstations.
- Two variations maintain popularity today, AT&T; System V based and the Berkeley Standard Distribution.
- Current versions (1/95)are System V release 4.2 .and 4.4 BSD
- Work is in progress to develop a Portable Operating System specification based on UNIX (IEEE POSIX committee).
