DAC -- acronym for Digital to Analog Converter, +which is a integrated circuit that converts intensity values to analog +signal values. This is used in video chipsets to produce the analog +signals that are sent to the monitor. Some DACs, known as RAMDACs +contain a palette look-up table. + +

Frame Buffer -- RAM that is part of the graphics hardware that +stores the pixel values that are converted into color intensity. +
Palette Look-Up Table -- a small table of +RAM that contains a set of RGB intensity values for +each index, of which there are 256 locations. The information in +this table is used by the DAC to generate the analog +signal. Also known as a Color Look-Up Table or CLUT. +
RAMDAC -- A DAC that contains a built-in palette +look-up table. + +
RGB -- acronym for Red, Blue & Green, which +describes the three primary colors of light that a CRT generates to produce +the range of visible colors. +
Super VGA -- see SVGA + +
SVGA -- acronym for Super-VGA, +which is a term applied to chipsets and the advanced functionality of those +chipsets that are above and beyond the capabilities of the original IBM +VGA chipset. +
VGA -- acronym for Video Graphics Array, which +is the term for IBM's successor to the EGA graphics chipset. This +term is also used when describing register compatible functions of other +chipsets such as SVGA chipsets. + +
