The VGA, which means Video Graphics Array or 'Video graphics collection' has been one of the most popular platforms of color of all time that relatively recently would be replaced by new and more modern compositions. However, today it is becoming to reuse in mobile devices that are simpler than the of the advanced computer color resolution.
Practically from the moment of its creation, VGA became almost exclusively in the colors of most computers support. This had to do with the fact that, unlike the previous models, the VGA was implemented as a single chip separated instead of requiring a variety of smaller chips. Thus, VGA could be installed directly on the mother or mother of computer space and simplify your Assembly. One of the characteristic elements of the VGA connector was of three external rows five-pin each for high densidas, while two rows are of low density. These connectors do much more simple and accessible connection video / VGA plate where not it comes already factory machine with it.
In addition, support VGA, by its resolution of 640 x 480 pixels allowed to obtain a palette of colors much more varied and comprehensive that previous holders. It contains 16 basic colors and 256 modes or tones of colors generated at the same time a number of 262144 colors palette values. In addition, for its implementation, the VGA chip required 256 KB of RAM memory capacity.
