CGA
Color Graphics Adapter. CGA was IBM's first colour graphics card and the first colour computer display standard for the IBM PC.
The highest resolution of any mode was 640×200 pixels, and the highest colour depth supported was 4-bit (16 colours).
The CGA card was succeeded in the consumer space by IBM's Enhanced Graphics Adapter (EGA) card, which supports most of CGA's modes and adds an additional resolution (640×350) as well as a software-selectable palette of 16 colours out of 64 in both text and graphics modes.
