VGA (Video Graphics Array)

A graphics adapter that offers 16 colors at a resolution of 640 pixels × 480 pixels. To gain more colors, VGA uses an analog video signal instead of a digital signal. With the analog signal, the VGA standard is able to provide 64 distinct levels for each color, giving users 643 or 262,144 possible colors. It uses a 15-pin, three-row, female DB-type connector.

Video Graphics Array adaptors (VGA) are currently used because they produce high quality graphics. The VGA adaptor provides up to 256 colors and also a high resolution. There are two typical combinations of resolution and color that a VGA provides:

• 640 x 480 pixels with 16 colors
• 320 x 200 pixels with 256 colors

The resolution and colors of various display adaptors can be different from the values given above, depending on who manufactures them. The VGA, like the EGA, is quite expensive.
