​KembaraXtra-Computer Terms – boss screen:
A boss screen is a feature in some older computer games that displays a fake, work-related screen to hide the game when someone, such as a supervisor, approaches. This allowed users to quickly disguise their activity without closing the game.
Boss screens were especially useful in MS-DOS environments, where switching between applications was slow or difficult. In modern systems like Windows or macOS, this feature is largely unnecessary because users can quickly switch between applications.
