Graphical User Interface
A Graphical User Interface (GUI) is a programming setup that allows the user to issue commands to the computer by interacting with images and other visually rendered elements on a screen.
Decades ago, GUIs opened the world of computing to the layman by allowing users an easier, more intuitive way of operating a computer than typing commands into DOS or using programming language. Today, the vast majority of users interact with their computers via one GUI or another.
While GUIs may vary, pointers, icons, windows and menus arranged in a desktop are common features.
