An improved variation of the VGA (Video Graphics Array) display standard, sometimes referred to as SVGA (Super VGA), Ultra VGA is a standard for computer screen display and resolution.
VGA is an analog format that replaced the preceding digital formats.
SVGA and other standards are developed and maintained by a consortium of monitor and graphics device manufacturers that calls itself VESA (Video Electronics Standards Association; http://www.vesa.org).

 Video Graphics Array - Gurupedia
While the VGA has been obsolete in original form for some time it was the last IBM standard that the majority of clone manufacturers decided to follow, making it even today the only standard graphics interface that be relied on to be present on the PC architecture.
VGA was technically superseded by IBM's XGA standard, but in reality it was superseded by the numerous extensions to the VGA by clone manufactuers that came to be known as Super VGA.
VGA adapters usually support both a monochrome and a color text mode, even though the monochrome mode is almost never used.

VGA is referred to as an "array" instead of an "adapter" because it was implemented from the start as a single chip (a gate array), replacing the Motorola 6845 and a full-length ISA board full of discrete components that the MDA, CGA and EGA used.
While the VGA has been obsolete in original form for some time it was the last IBM standard that the majority of PC clone manufacturers decided to follow, making it even today the only standard graphics interface that can be relied on to be present on the PC architecture.
The video memory of the VGA is mapped to the PC's memory via a window in the range between 0xA000 and 0xBFFFF in the PC's real mode address space.

 Video Graphics Info
On most computers, the graphics card converts digital information to analog information for display on the monitor; on laptops, the data remains digital because laptop displays are digital.
Video Interface: The next thing that the graphics card needs is a way to generate the signals for the monitor.
This means that the graphics card scans the entire memory array 1 bit at a time and does this 60 times per second.

SBP is the total number of pixels in a sensor calculated either by dividing the array area by the area of a single pixel or by multiplying the number of pixel rows by the number of pixel columns.
For example, the SBP of a VGA image sensor is 19.63 / 0.00003136 = 307,200 or 640H x 480V = 307,200.
