1. A design for the part of a program that interacts with the use and uses icons to represent programs features. The Apple Macintosh and Microsft Windows operating environments are popular GUIs. Having found that people recognise graphic representations faster they read word or phreases, a Xerox research team designed a user interface with graphic images called icons. GUIs typically work with moussable interfaces with pull-down menus, dialog boxes, check boxes radio buttons, drop-down list boxes, scroll bars, scroll boxes, and the like. Progams with a GUI require a computer with suffceint speed, power, and memory to display high-resolution, bit-mapped display. From QUECID
