GUI: Graphical User Interface

The full form of GUI is “Graphical User Interface“. A graphical user interface (GUI) is a computer program that allows a person to communicate with a computer through the use of symbols, icons, menus, visual metaphors, pointing devices and other representations of visual indicators (graphics) to display information and controls related user interface, unlike text-based interfaces, where data and commands are in text. Best known for its implementation in the Macintosh operating system of Apple Inc. and Windows, of Microsoft Corporation, the GUI replaced the difficult textual interfaces of previous computing with a relatively intuitive system that made the operation of the computer not only Easier to learn, but also more natural and enjoyable.

GUIs were introduced in response to the perceived steep learning curve of command-line interfaces (CLIs), which require that commands be entered on a computer keyboard. The GUI is now the standard interface of the computer and its components have become unmistakable cultural artifacts. GUI representations are manipulated by a pointing device, such as a mouse, trackball, pen or fingers on the touch screen.
