<Storage> The memory in a computer' SgraphicS adaptor, uSed to Store the image diSplayed on a bitmap diSplay. Often thiS iS built uSing VRAM chipS. 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)
