<h2>VGA stands for Video Graphics Array, sometimes referred to as Video Graphics Adapter. </h2>

<p>It offers many different video modes, from 2 color to 256 color, and resolutions from 320x200 to 640x480. These notesfocus on the 256-color mode, known as mode 0x13. In mode 0x13, the screen dimensions are 320 pixels in width and 200 pixels in height. Since this is a 256-color mode, each pixel represents <a href='binary.html'>one byte</a>, so the memory needed is 320*200 or 64,000 bytes. </p>
