Which feature is traditionally associated with desktops rather than mobile operating systems?

• A. Multitasking with overlapping windows
• B. Touchscreen input
• C. Battery management
• D. App sandboxing

Answer: (A)

Desktops have long relied on a window-based interface where many programs can run at once, with their windows able to overlap, be moved, resized, minimized, or maximized. This multi-window environment supports flexible multitasking on larger screens with precise input from a mouse and keyboard. Mobile operating systems, by contrast, usually emphasize full-screen apps and non-overlapping task cards, with multitasking that doesn’t center on overlapping windows. So the best match for the question is multitasking with overlapping windows. The other features show up on both types of systems in various forms, but they aren’t the defining desktop characteristic: touchscreen input is more tied to mobile devices (though some desktops have touch screens); battery management is important on all devices but is especially critical for mobile; and app sandboxing is a security approach used on both, though more emphasized in mobile contexts.
