Graphical User Interface

Definition

A graphical user interface (GUI) is a visual way for users to interact with a computer or software, using graphical elements like windows, icons, buttons, and menus. This interface allows users to navigate and control the system without needing to memorize command-line instructions, making technology more accessible to a wider audience. The development of GUIs has transformed how people use computers and has influenced various types of operating systems throughout their evolution.
