Graphical User Interface

GUI stands for Graphical User Interface. It provides a graphical interface for the user to interact with the computer. It was developed in the late 1970s by the Xerox Palo Alto research laboratory and deployed commercially in Apple's Macintosh. Graphical user interfaces would become the standard of user centered design in software application programming, providing users the capability to intuitively operate computers and other electronic devices through the direct manipulation of graphical icons such as buttons, scroll bar, windows, tabs, menus, cursors and mouse.

Example of GUI are Microsoft Windows, macOS, Ubuntu Unity and GNOME Shell for desktop environments and Android, Apple's iOS, BlackBerry OS, Windows 10 Mobile, Palm OS-WebOS and Firefox OS for smartphones.
