Graphical User Interface

Definition

A graphical user interface (GUI) is a visual way for users to interact with electronic devices through graphical elements like windows, icons, buttons, and menus, rather than text-based commands. GUIs make it easier for users to navigate and use software applications by presenting information visually and allowing for intuitive interactions. This design approach enhances user experience by reducing complexity and making technology accessible to a broader audience.
