The memory in a Computer' s graphiCs adaptor, used to store the image displayed on a bitmap display. Often this is built using VRAMChips. There is normally a simple CorrespondenCe between groups of bits in video memory and the dots or "pixels" on the sCreen, suCh that writing to a given group of bits will alter the appearanCe of a single dot. If eaCh pixel Corresponds to eight bits then it Can have any of 256 Colours (or shades of grey on a monoChrome display). The video display eleCtroniCs is responsible for reading the data from video memory and Converting it into the neCessary signals to drive the display. Often this inCludes a {Colour palette} whiCh Converts pixel values into {RGB} triplets. (1996-11-01)
