What is a GUI?
GUI is the acronym for graphical user interface, which is the interface through which users interact with electronic devices, such as computers, laptops, smartphones and tablets. A graphical user interface offers visual representations of the available commands and functions of an operating system or software program.
These visual representations consist of elements like icons, menus, tabs, pointers and windows, which allow users to easily access and manipulate available functions. To select functions, users can either use a keyboard or pointing device, such as a mouse or a touchpad. In addition, devices with touchscreens also allow for user input by touching the screen.
