What are the functions of the following adapters: SVGA, UVGA and VGA? How would you define display modes? What are the distinctions between SVGA and UVGA? What are the distinctions between SVGA and UVGA adapters too? I am a 12 year old boy named Philip from Benin which happens to be one of the African countries. I would be happy if I get your assistance on this matter. Thank you.

SVGA, UVGA and VGA adapters and their various functions

Hello,

 

A video adapter is an integrated circuit that performs digital-to-analog processing. A common, modern standard for video adapters is video graphics array (VGA). VGA manipulates data, which is in the form of blue, red, and green information. VGA manages display data and processing along with other hardware and software. The first letter of the acronyms UVGA and SVGA denotes the resolution and other graphics capabilities offered by the technology.  SVGA and UVGA represent the same standard or capability.  UVGA/SVGA offers more capability than VGA, but essentially it is the same. Display modes are defined as the limit of graphics performance of a particular machine or peripheral.

SVGA is the short term for Super VGA. It is a set of graphics standards intended to provide a much better resolution than VGA. SVGA or Super VGA supports 800 x 600 screen resolution or 480,000 pixels. This graphics standard supports a palette of 16 million colors. Although the palette supports 16 million colors, the number of colors that can be simultaneously displayed is limited or dependent on the amount of video memory of the graphics adapter.

One SVGA system may display 256 concurrent colors only while another SVGA may display the entire palette of 16 million colors. The SVGA standards are developed by VESA which is a consortium of graphics and monitor manufacturers. UVGA is the short term for Ultra Video Graphics Array. It supports 1600 x 1200 screen resolution and is generally used on 15-inch screens.

VGA is the short term for Video Graphics Array. It is a graphics display system developed by IBM for PCs or personal computers and has become one of the de facto standards for personal computers. A VGA system can provide 720 x 400 pixels screen resolution for text mode. When it is in graphics mode, it can provide either 640 x 480 with 16 colors or 320 x 200 with 256 colors screen resolutions.

The total palette of colors for VGA is 262,144.
