VGA technology is an analog interface, or connection device, used between a computer system and monitor, or other display device. VGA hardware is used to facilitate a digital signal which enables a display device to show an image. VGA refers to a specific resolution, or level of information displayed, of 640-by-480 pixels. Pixels are the smallest element in an image.

RGB VGA Connection
-
VGA technology is accessed between devices, such as computers and monitors, via a VGA connector, or cable with a 15-pin plug and socket. VGA connectors carry analog signals. Analog, or continuous signals, offer a higher density than digital signals, resulting in higher signal resolution. This resolution enables VGA connectors to support a wide range of RGB colors.
