What is the Full Form of VGA ?

VGA - Video Graphics Array

Video Graphics Array is a display standard developed by IBM in 1987. It provides a resolution of 640 x 480 pixels with a refresh rate of 60Hz. VGA is referred to as an "array" instead of an "adapter" because it was implemented from the start as a single chip (an ASIC). It uses analog signals rather than digital signals.

A standard VGA connector has 15 pins and is shaped like a trapezoid. A monitor designed for the older standards may not be able to work with Video Graphics Array standard.

Many revisions of the standard have been introduced after its basic version. The most common is Super VGA (SVGA), which allows for resolutions greater than 640x480, such as 800x600 or 1024x768.
