A car’s airbag controller must deploy within a few milliseconds of a crash being detected, every time. Which kind of operating system suits it?
Correct answer C. Hard real-time operating system
Explanation
A hard real-time system guarantees that critical tasks finish within their deadlines; a missed deadline counts as system failure, as it would for an airbag. A soft real-time system only gives critical tasks priority and tolerates occasional misses, which suits media playback. Time-sharing and batch systems optimise response time or throughput and give no deadline guarantees at all.
