Short for Random Access Memory Digital-to-Analog Converter, a single chip on video adapter cards. The RAMDAC's role is to convert digitally encoded images into analog signals that can be displayed by a monitor. A RAMDAC actually consists of four different components - SRAM to store the color map and three digital-to-analog converters (DACs), one for each of the monitor's red, green, and blue electron guns.
