BSD
:BSD: /B-S-D/ n. [abbreviation for `Berkeley Software Distribution'] a
family of Unix
} versions for the DEC
VAX
and PDP-11 developed by
Bill Joy and others at Berzerkeley
starting around 1977, incorporating
paged virtual memory, TCP/IP networking enhancements, and many other
features. The BSD versions (4.1, 4.2, and 4.3) and the commercial
versions derived from them (SunOS, ULTRIX, and Mt. Xinu) held the
technical lead in the Unix world until AT&T's successful standardization
efforts after about 1986; descendants including Free/Open/NetBSD, BSD/OS
and MacOS X are still widely popular. Note that BSD versions going back
to 2.9 are often referred to by their version numbers alone, without the
BSD prefix. See 4.2
, and Unix
