Gui is a graphical user interface that allows users to interact with electronic devices through visual elements like icons, buttons, and menus. Unlike command-line interfaces, which require text-based commands, Gui makes it easier for people to navigate software and perform tasks by using a mouse or touch gestures. Gui is commonly found in operating systems like Windows, macOS, and Linux, as well as in applications such as web browsers and mobile apps. It enhances user experience by providing intuitive controls and visual feedback, making technology more accessible to a wider audience.
