icon

graphics A small picture intended to represent something (a

file, directory, or action) in a graphical user interface.

When an icon is clicked on, some action is performed such as

opening a directory or aborting a file transfer.

Icons are usually stored as bitmap images. MicrosoftWindows uses a special bitmap format with file name extension

".ico" as well as embedding icons in executable (".exe") and

Dynamically Linked Library (DLL) files.

The term originates from Alan Kay's theory for designing

interfaces which was primarily based on the work of Jerome

Bruner. Bruner's second developmental stage, iconic, uses a

system of representation that depends on visual or other

sensory organization and upon the use of summarising images.
