VGA Abbrev. for video graphics array. A color graphics adapter that is available for some models of the IBM PS/2 series. Adapters to the VGA standard are produced by other manufacturers to fit into non-IBM computers. The VGA can generate a 640 × 480 16-color screen in addition to all the modes of the now-obsolete EGA and MCGA adapters, including a 16-color screen of 640 × 350, 640 × 200, or 320 × 200 pixels and a 320 × 200 256-color screen. Multiple graphics pages are available so that a range of animation techniques are possible. VGA is analog in composition: each of the three colors that constitute the image can take on a range of intensities between zero and a maximum value. See also SVGA.
