GUI stands for Graphical User Interface in the context of computing. It is a user interface that allows users to interact with electronic devices through graphical icons and visual indicators rather than text-based commands. GUIs make software more accessible to the general public by simplifying navigation and task execution. Users can perform actions like opening files or executing commands simply by clicking on icons or buttons. This approach has become prevalent in various operating systems and applications, as it enhances the user experience, making technology easier to use for individuals with varying levels of technical expertise.
