gui - Computer Definition
Pronounced gooey. A visual computer environment that uses graphical images such as icons, menus, and dialog boxes to represent files, file folders, programs, and options to ease the interface between the user and the computer. The user can use a mouse, keypad, thumbpad, or other device to manipulate an icon, button, scroll bar, check box, or other graphical item to activate a routine to activate a program feature, such as opening or closing a file.The first GUI was invented by a research team at the Xerox Palo Alto Research Center (Xerox PARC). GUI has largely superseded the Command Line Interface (CLI) in computer and communications gear except for routers and switches.
(Graphical User Interface) The common method of interacting with a computer that allows any graphics image to be displayed on screen. Except for entering text on the keyboard, the primary way the computer is operated is with a mouse or touchpad pointing device. The mouse/touchpad is used to select icons and menu options as well as move and resize windows that frame the application and elements within it. The major GUIs are Windows and Mac along with GNOME and KDE for Linux. With the advent of the Macintosh in the mid-1980s and Windows in the 1990s, GUIs replaced the character-based display with a graphics display and eliminated the need to enter cryptic commands in a required sequence. In addition, fonts could be changed and resized on screen, providing a what-you-see-is-what-you-get (WYSIWYG) capability for creating printed materials. However, all major operating systems still include a command line interface that lets programmers and power users enter commands to perform certain tasks faster and more easily than with a mouse (see command line). See user interface, UI types, drag and drop, desktop manager, window manager and Star.
