In computing, the term "GUI" refers to a Graphical User Interface. This interface allows users to interact with computers and software applications using graphical elements such as windows, icons, buttons, and menus, rather than relying solely on text-based commands. GUIs enhance user experience by making digital systems intuitive and accessible to a wider audience, including those with minimal technical knowledge. Popular examples of GUIs include the interfaces of operating systems like Windows and macOS, as well as various software applications and mobile apps.
