What does an RTOS guarantee that a regular OS might not?
✗ Incorrect
An RTOS guarantees tasks finish within strict time limits, which is not guaranteed by regular OS.
Which of these is a key feature of an RTOS?
✗ Incorrect
Task scheduling with priorities helps RTOS manage time-critical tasks efficiently.
In which device would you most likely find an RTOS?
✗ Incorrect
Pacemakers require precise timing, so they use RTOS.
What does determinism mean in the context of RTOS?
✗ Incorrect
Determinism means tasks complete predictably within set time limits.
Which of these is NOT a typical RTOS responsibility?
✗ Incorrect
Playing music files is an application task, not a core RTOS responsibility.
