    [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 also Unix.

    (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.
