Concept in Definition ABC

The acronym VGA is used to refer to the color system created by IBM in the late 1980s for its computers and processors. The VGA, which stands for Video Graphics Array or 'Collection Video Graphics' has been one of the most popular color platforms of all time that would be replaced relatively recently by newer and more modern compositions. However, today it is being reused in mobile devices that have resolution simpler colors than advanced computers.

Practically from the moment of its creation, VGA became almost exclusively the color support of most computers. This had to do with the fact that, unlike previous models, VGA was implemented as a single chip separate from the rest rather than requiring a variety of smaller chips. Thus, the VGA could be installed directly on the mother or space mother of the computer and simplify its assembly. Another characteristic element of the VGA was the external connector with three rows of five pins each for high density, while the two rows are low.

density. These connectors make the connection of the video or VGA card much simpler and more accessible in the event that it does not already come from the factory. machine with her.

In addition, the VGA support, due to its resolution of 640 x 480 pixels, allowed obtaining a color palette much more varied and complete than the previous supports. It contains 16 basic colors and 256 modes or shades of colors that in turn generate an amount of 262144 values of color palette. In addition, for its implementation, the VGA chip required a capacity of 256 KB of RAM.
