operating system (BSD) A family of
Unix versions developed by
Bill Joy and others at the
University of California at Berkeley, originally for the
DEC VAX and
PDP-11 computers, and subsequently ported to almost all modern general-purpose computers. BSD Unix incorporates
paged virtual memory,
TCP/IP networking enhancements and many other features.
BSD UNIX 4.0 was released on 1980-10-19. The BSD versions (4.1, 4.2, and 4.3) and the commercial versions derived from them (
SunOS,
ULTRIX, Mt. Xinu,
Dynix) held the technical lead in the Unix world until
AT&T's successful standardisation efforts after about 1986, and are still widely popular.
