+<B>Introduction</B>
+<BR> This page is a glossary
+covering video programming related terms. It is extremely difficult
+for me to determine which terms should be included in this page, thus if
+you have come here looking for a particular term and are dismayed at not
+finding it listed here, please send a note with the <A HREF="feedback.htm">Feedback
+Form</A> including the term in the body of the message, and it will be
+added here.

+<P><A NAME="DAC"></A><B>DAC</B> -- 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.

+
+
+<P><A NAME="PLUT"></A><B>Palette Look-Up Table</B> -- a small table of
+RAM that contains a set of <A HREF="#RGB">RGB</A> intensity values for
+each index, of which there are 256 locations. The information in
+this table is used by the <A HREF="#DAC">DAC</A> to generate the analog
+signal. Also known as a Color Look-Up Table or CLUT.

+
+<P><A NAME="RGB"></A><B>RGB</B> -- acronym for Red, Blue & Green, which
+describes the three primary colors of light that a CRT generates to produce
+the range of visible colors.

+
+<P><A NAME="SVGA"></A><B>SVGA </B>-- acronym for Super-<A HREF="#VGA">VGA</A>,
+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
+<A HREF="#VGA">VGA</A> chipset.
+<CENTER><A NAME="V"></A><B>------ V ------</B></CENTER>
+
+
+<P><A NAME="VGA"></A><B>VGA</B> -- 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.
