Graphics
A graphic is an image or visual representation of an object. Therefore, computer graphics are simply images displayed on a computer screen. Graphics are often contrasted with text, which is comprised of characters such as numbers and letters, rather than images.
Computer graphics can be either two or three-dimensional. Early computers only supported 2D monochrome graphics, meaning they were black and white. Eventually, computers began to support color images. While the first machines only supported 16 or 256 colors, most computers can now display graphics in millions of colors.
