DefinitionA GUI (Graphical User Interface) is a user interface that shows graphics such as icons, buttons, and windows on the screen and lets users operate it by pointing at them with a mouse or by touch.
ExplanationBecause what you operate is visible, you can look at the screen and choose without remembering command names. The list boxes, menus, and other controls from earlier units are all building blocks of a GUI. GUI screens still involve some typing, and helper features are provided to cut down that effort.
AnalogyIt is like ordering by pointing at a menu with photos. You can choose by sight even if you do not know the name of the dish.
Memory hookThe G at the front stands for Graphical, which, like graph, refers to something drawn. Remember it as operating by pointing at drawn pictures.
