      n 1: the last (12th) month of the year [syn: December, Dec]
      2: (astronomy) the angular distance of a celestial body north or
         to the south of the celestial equator; expressed in degrees;
         used with right ascension to specify positions on the
         celestial sphere [syn: declination, celestial latitude,
         dec]

From V.E.R.A. -- Virtual Entity of Relevant Acronyms (September 2014) :

From The Jargon File (version 4.4.7, 29 Dec 2003) :

  DEC
   /dek/, n.
  
      n. Commonly used abbreviation for Digital Equipment Corporation, later
      deprecated by DEC itself in favor of ?Digital? and now entirely obsolete
      following the buyout by Compaq. Before the killer micro revolution of the
      late 1980s, hackerdom was closely symbiotic with DEC's pioneering
      timesharing machines. The first of the group of cultures described by this
      lexicon nucleated around the PDP-1 (see TMRC). Subsequently, the PDP-6, {
      PDP-10, PDP-20, PDP-11 and VAX were all foci of large and important
      hackerdoms, and DEC machines long dominated the ARPANET and Internet
      machine population. DEC was the technological leader of the minicomputer
      era (roughly 1967 to 1987), but its failure to embrace microcomputers and
      Unix early cost it heavily in profits and prestige after silicon got
      cheap. Nevertheless, the microprocessor design tradition owes a major debt
      to the PDP-11 instruction set, and every one of the major general-purpose
      microcomputer OSs so far (CP/M, MS-DOS, Unix, OS/2, Windows NT) was either
      genetically descended from a DEC OS, or incubated on DEC hardware, or both.
      Accordingly, DEC was for many years still regarded with a certain wry
      affection even among many hackers too young to have grown up on DEC
      machines.
  

From The Free On-line Dictionary of Computing (18 March 2015) :

  dec
  
      /dek/ decrement, decrease by one.  Especially
     used by assembly language programmers, as many assembly
     languages have a "dec" mnemonic.
  
     Opposite: inc.

From The Free On-line Dictionary of Computing (18 March 2015) :

  Digital Equipment Corporation
  DEC
  
      (DEC) A computer manufacturer and software
     vendor.
  
     Before the killer micro revolution of the late 1980s,
     hackerdom was closely symbiotic with DEC's pioneering
     time-sharing machines.  The first of the group of hacker
     cultures nucleated around the PDP-1 (see TMRC).

     machines long dominated the ARPANET and Internet machine
     population.
  
     The first PC from DEC was a CP/M computer called Rainbow,
     announced in 1981-82.
  
     DEC was the technological leader of the minicomputer era
     (roughly 1967 to 1987), but its failure to embrace
     microcomputers and Unix early cost it heavily in profits
     and prestige after silicon got cheap.  However, the
     microprocessor design tradition owes a heavy debt to the
     PDP-11 instruction set, and every one of the major
     general-purpose microcomputer operating systems so far
     (CP/M, MS-DOS, Unix, OS/2) were either genetically
     descended from a DEC OS, or incubated on DEC hardware or
     both.  Accordingly, DEC is still regarded with a certain wry
     affection even among many hackers too young to have grown up
     on DEC machines.  The contrast with IBM is instructive.
  
     Quarterly sales $3923M, profits -$1746M (Aug 1994).
  
     DEC was taken over by Compaq Computer Corporation in 1998.
     In 2002 Compaq was in turn acquired by Hewlett-Packard who
     sold off parts of Digital Equipment Corporation to Intel and
     absorbed the rest.  The Digital logo is no longer used.
