The acronym GUI stands for Graphical User Interface. It refers to the visual components of software interfaces that allow users to interact with electronic devices through graphical elements such as icons, buttons, and windows. GUIs enhance user experience by making software more intuitive and accessible to individuals without a technical background. By simplifying interactions, GUIs enable users to focus on tasks rather than learning complex commands. As technology evolves, GUIs continue to integrate more advanced features, such as touch interfaces and voice recognition, to improve user engagement and workflow efficiency.
