from The Free On-line Dictionary of Computing (8 July 2008)

frame buffer

   <hardware> Part of a video system in which an {image} is
   stored, {pixel} by pixel and which is used to refresh a
   {raster} image.  The term "{video memory}" suggests a fairly
   static display whereas a frame buffer holds one frame from a
   sequence of frames forming a moving image.

   Frame buffers are found in {frame grabbers} and {time base
   correction} systems, for example.
