In the world of personal computing, the acronym CGA stands for Color Graphics Adapter. This piece of hardware, developed by IBM in the early 1980s, was a revolutionary step in bringing color to computer displays. While it may seem archaic compared to today's high-resolution screens, CGA played a pivotal role in shaping the visual landscape of early PCs.
A Brief Look Back:
The CGA card, a small circuit board, was designed to be plugged into the IBM PC/XT. It was one of the first graphics standards to offer color capabilities, offering a limited palette of four colors: black, white, green, and brown (often mistaken as red). While seemingly limited, this was a major advancement from the monochrome displays prevalent at the time.
Features & Limitations:
The Impact:
Despite its limitations, CGA had a significant impact on the early personal computing scene:
CGA Today:
While CGA is no longer used in modern computers, its legacy remains. Its impact on the development of computer graphics is undeniable. Today, the retro aesthetic of CGA graphics is often embraced in modern pixel art and retro-inspired gaming, providing a nostalgic reminder of the early days of computing.
In Conclusion:
CGA, though a simple and limited technology by today's standards, played a crucial role in the evolution of personal computing. It brought color to the masses, paved the way for more advanced graphics cards, and inspired generations of developers and gamers. While its time has passed, CGA remains a symbol of the innovation and evolution that has characterized the world of computing.

Instructions:
Imagine you are a game developer creating a simple game for a CGA-equipped computer. Your game involves a character moving across the screen.
Task:
There is no single "correct" answer for this exercise. Here is an example:
Character Design:
A simple spaceship with a white body, a green window, and brown (red) thrusters. The black color will be used for the background.
Design Choices:
The white body provides a good contrast against the black background, making it easy to see. The green window adds a touch of color and detail, while the brown (red) thrusters suggest movement and action. The limited color palette forces a focus on simple shapes and high-contrast visuals, which is characteristic of CGA graphics.
