ITPEC IP April 2018 — Question 90 of 100

The requirement that a process finish within a specified time is real-time ability. In an embedded system, correctness may depend not only on the output value but also on producing it before a deadline so the controlled device can respond safely.

Answer (c)

Why not others:
- availability is the ability to use the system when needed

- reliability is continued correct operation over time

- serviceability is the ease and speed of maintenance or repair

Key rule: A real-time system guarantees timing constraints; a fast average response without deadline assurance is not sufficient.
