Pictures created and manipulated through the use of computer devices. The term computer graphics generally pertains to any computer device or program that makes a computer capable of displaying and manipulating pictures. For example: a laser printer is said to be a computer graphics device because it allows the computer to output pictures; likewise, a computer display monitor can display pictures. Computer graphics are used for various applications including publishing, education, entertainment, and advertising, or wherever pictures are deemed reasonable or necessary in the creation of a message. They are also used very effectively in situations where there is a need for computed data to be visualized, such as in statistical charts or graphs of mathematical data. Most computer graphics can also be drawn by an artist, but the computer can accomplish much more in a much shorter period of time. One of the major benefits of computer graphics is that images can be manipulated with relative ease and that a multitude of visual effects are possible because the images can be played with over and over again until a desired effect is achieved.
