(GUI is usually pronounced "gooey") A style for presenting program choices using graphic elements rather than just strings of text. Two of the better-known examples include the Macintosh and Windows user interfaces. According to most users, GUIs are easier to learn and use than the older "command line interfaces" (CLIs), such as the one used by MS-DOS (an older operating system). But some power users say the tradeoff is less powerful commands, more system resources occupied with presentation rather than processing, and less command flexibility.
Almost all GUIs for computers use a full "WIMP" (windows, icons, menus, pointing device) configuration. But more specialized devices, such as video equipment or handheld organizers, often use a more simple "point-and-shoot" implementation.
