Graphics are computer images displayed on a monitor. 'Graphic' means 'an image created by drawing or painting'. Computer graphics are images displayed on a computer screen. Although a screen is two-dimensional (2D), special software can help in creating 3D graphics such as you would see in a video game. Graphics programs can help us to edit photographs, illustrate text documents, make graphs and charts, or create works of art, as well as play games.
