background
 n.,adj.,vt.

   [common] To do a task in background is to do it whenever {foreground}
   matters are not claiming your undivided attention, and to background
   something means to relegate it to a lower priority. "For now, we'll
   just print a list of nodes and links; I'm working on the
   graph-printing problem in background." Note that this implies ongoing
   activity but at a reduced level or in spare time, in contrast to
   mainstream `back burner' (which connotes benign neglect until some
   future resumption of activity). Some people prefer to use the term for
   processing that they have queued up for their unconscious minds (a
   tack that one can often fruitfully take upon encountering an obstacle
   in creative work). Compare {amp off}, {slopsucker}.

   Technically, a task running in background is detached from the
   terminal where it was started (and often running at a lower priority);
   oppose {foreground}. Nowadays this term is primarily associated with
   {Unix}, but it appears to have been first used in this sense on
   OS/360.
    

background

   1. <operating system> A task running in the background (a
   background task) is detached from the terminal where it was
   started (and often running at a lower priority); opposite of
   {foreground}.  This means that the task's input and output
   must be from/to files (or other processes).

   Nowadays this term is primarily associated with {Unix}, but it
   appears to have been first used in this sense on {OS/360}.

   Compare {amp off}, {batch}, {slopsucker}.

   2. <jargon> For a human to do a task "in the background" is to
   do it whenever {foreground} matters are not claiming your
   undivided attention, and "to background" something means to
   relegate it to a lower priority.  "For now, we'll just print a
   list of nodes and links; I'm working on the graph-printing
   problem in the background."  Note that this implies ongoing
   activity but at a reduced level or in spare time, in contrast
   to mainstream "back burner" (which connotes benign neglect
   until some future resumption of activity).  Some people prefer
   to use the term for processing that they have queued up for
   their unconscious minds (often a fruitful tack to take upon
   encountering an obstacle in creative work).
