Vga Card ( Video Graphics Arrays )

Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987,^[1] but through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640×480 resolution itself. While this resolution was superseded in the personal computer market in the 1990's, it is becoming a popular resolution on mobile devices.

VGA was the last graphical standard introduced by IBM that the majority of PC clone^[update] manufacturers conformed to, making it today (as of 2010) the lowest common denominator that all PC graphics hardware supports, before a device-specific driver is loaded into the computer.^{[citation needed]} For example, the MS-Windows splash screen appears while the machine is still operating in VGA mode, which is the reason that this screen always appears in reduced resolution and color depth.
