The Monochrome Display Adapter (MDA) is the oldest video adapter board.
MDA boards are for their use of a 25-pin parallel port included with the 9-pin video connector.
The Color Graphics Adapter (CGA) is same as MDA and it is the first graphics adapter to introduce color to PC displays.
A CGA board can be identified by a round RCA-type connector located just above a 9-pin video connector.
The Enhanced Graphics Adapter (EGA) offers more colors and higher display resolution than CGA.
The Video Graphics Array (VGA) board up to 262,144 possible colors for ordinary VGA. VGA connector as a 15-pin high-density connector SVGA (or Super VGA) extends the capabilities of VGA by adding more resolutions and color depths allowing as many as 16 million colors (known as true
color mode) to be displayed at one time.
