Fullscreen Mode is a display option that allows applications, websites, or games to occupy the entire screen, hiding the taskbar and other interface elements. This mode enhances the user experience by providing an immersive environment, making it easier to focus on the content without distractions. Users can typically enter Fullscreen Mode by clicking a button or pressing a specific key, such as F11 on many web browsers. Exiting this mode is usually just as simple, allowing users to return to their standard view whenever they choose.
