A portion of a computer's main memory or an add-on card which stores the contents of a displayed image pixel-by-pixel and which is used to refresh the screen display. The color depth of the frame buffer—be it 8-Bit color, 16-Bit color, etc.—determines the number of bits per pixel—or, in other words, the total number of different colors—that can be displayed. Also known as a screen buffer, and display buffer.
