graphics adaptor definition
<hardware, graphics> (Or "graphics adapter", "graphics card",
"video adaptor", etc.) A circuit board fitted to a computer,
especially an IBM PC, containing the necessary video
memory and other electronics to provide a bitmap display.
Adaptors vary in the resolution (number of pixels) and
number of colours they can display, and in the refresh rate
they support. These parameters are also limited by the
monitor to which the adaptor is connected. A number of such
display standards, e.g. SVGA, have become common and
different software requires or supports different sets.

Graphics Interchange Format definition
<graphics, file format> /gif/, occasionally /jif/ (GIF, GIF
89A) A standard for digitised images compressed with the
LZW algorithm, defined in 1987 by CompuServe (CIS).
Graphics Interchange Format and GIF are service marks of
CompuServe Incorporated. This only affects use of GIF
within Compuserve, and pass-through licensing for software to
access them, it doesn't affect anyone else's use of GIF. It
followed from a 1994 legal action by Unisys against CIS for
violating Unisys's LZW software patent. The CompuServe
Vice President has stated that "CompuServe is committed to
keeping the GIF 89A specification as an open, fully-supported,
non-proprietary specification for the entire on-line community
including the World-Wide Web".
Filename extension: .gif.

Graphics Language Object System definition
<graphics, language> (GLOS) A language with statements for
describing graphics objects (line, circle, polygon, etc.),
written by Michael J McLean and Brian Hicks at the University
of Queensland, St. Lucia in 1978. New objects are defined
using procedures. 2-D transformations are context dependent
and may be nested.

PhD thesis, University of Queensland, 1978].

Describing Line Objects", Proceedings of the DECUS-Australia
August 1973 Symposium, Melbourne, 1973].
