Icon
This article is concerned with the religious images called icons, principally in
Eastern Christianity; for other senses of this word see
icon (disambiguation). An icon (from
Greek , eikon, "image") is an image, picture, or representation; it is a sign or likeness that stands for an object by signifying or representing it, or by analogy, as in
semiotics; by extension, icon is also used, particularly in modern popular culture, in the general sense of
symbol — i.e. a name, face, picture, edifice or even a person readily recognized as having some well-known significance or embodying certain qualities. one thing, and image or depiction, that represents something else of greater significance thru literal or figurative meaning, usually associated with religious, cultural, political, and economic standing.

Icon
<
language> A descendant of
SNOBOL4 with
Pascal-like syntax, produced by Griswold in the 1970's. Icon is a general-purpose language with special features for string scanning. It has dynamic types: records, sets, lists, strings, tables. If has some
object oriented features but no
modules or
exceptions. It has a primitive
Unix interface.
The central theme of Icon is the generator: when an expression is evaluated it may be suspended and later resumed, producing a result sequence of values until it fails. Resumption takes place implicitly in two contexts: iteration which is syntactically loop-like ('every-do'), and goal-directed evaluation in which a conditional expression automatically attempts to produce at least one result. Expressions that fail are used in lieu of Booleans. Data
backtracking is supported by a reversible
assignment. Icon also has
co-expressions, which can be explicitly resumed at any time.

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.
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.
