The full form of CGA is Color Graphics Adapter. It was an early graphics card used in IBM PC-compatible computers during the 1980s. IBM made the CGA in 1981 as a cheaper alternative to its monochrome display adapter (MDA), which could only show text in a single color. The CGA, on the other hand, could display up to 16 colors at a resolution of 320 x 200 pixels, or four colors at a resolution of 640 x 200 pixels.
In this article, we will discuss the full form of CGA, its history, features, and its impact on the personal computer industry.

History of CGA
As mentioned earlier, the CGA was introduced by IBM in 1981. It was a significant upgrade from the MDA, which was the first display adapter for the IBM PC. The MDA could only display text in a single color, while the CGA could display graphics in up to 16 colors. This made the CGA a much more versatile and attractive option for personal computer users.
Features of CGA
The CGA was capable of displaying graphics in two modes: graphics mode and text mode. In graphics mode, the CGA could display up to 16 colors at a resolution of 320 x 200 pixels. In text mode, the CGA could display up to 80 columns of text with a resolution of 640 x 200 pixels.
The CGA also had a built-in character generator that could display both uppercase and lowercase characters, as well as special characters such as symbols and foreign language characters.

Impact of CGA
The introduction of the CGA had a significant impact on the personal computer industry. It was the first graphics card that could display color graphics on a personal computer, which was a major breakthrough at the time. The CGA allowed for the creation of more sophisticated and visually appealing software, games, and other applications, which helped to drive the popularity of personal computers.
In addition to its impact on the software industry, the CGA also paved the way for future developments in graphics technology. The CGA was eventually replaced by newer and more advanced graphics cards, such as the Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA), which offered higher resolutions and more colors.
Conclusion
The CGA was a significant milestone in the history of personal computers. It was the first graphics card that could display color graphics on a personal computer, which helped to drive the popularity of personal computers in the 1980s. Although the CGA has long been obsolete, its legacy lives on in the advanced graphics technology that we use today.
