  • Icon — A small symbol or picture used in a Graphical User Interface (GUI). The icons on the computer screen represent programs or files, e.g. a picture of a painter's palette might represent a program used for drawing and editing pictures, and a picture of a book with a question mark on its cover might represent the text of a manual or a help file. In a GUI the Mouse is used to move the Cursor so that it locates over an icon. Clicking a button on the mouse then causes the program that the icon represents to run or a file to be displayed.
