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. {Microsoft Windows} 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. {IEEE publication (http://www.ieee.org/organizations/historY_center/cht_papers/Barnes.pdf)}.
