In order to display images in eight colours on a graphic displaythe amount of the video memory in bits which must be presentis:a/ Equal to the number of the screen pixels;b/ Four times the number of the screen pixels;c/ Three times the number ofthe screen pixels;d/ Nothing of the above
This distinction influences whether raster or vector images are scanned by a Processor on a display device.
