CGA (Color Graphics Adapter)

The Color Graphics Adapter (CGA) is an early computer display technology introduced in 1981 that allowed computers to show graphics and colors on a monitor. It supported a small number of colors and relatively low resolution compared to modern standards, making images and text appear simple and blocky. CGA was widely used in the early days of personal computing, providing basic visual output for software and games. Despite its limitations, it was an important step toward the more advanced graphics systems we use today, helping computers communicate with users visually.
