ITPEC IP October 2023 Question 88
ITPEC IP October 2023 — Question 88 of 100
The requirement that processing finish within a specified time is real-time ability. A real-time system must respond before its deadline; correctness depends not only on the computed result but also on when that result is produced. Embedded control systems often have strict timing constraints tied to physical events.
Answer (c)
Why not others:
- (a) Availability is the proportion of time the system is ready for use
- (b) Reliability is the ability to operate correctly without failure for a specified period
- (d) Serviceability concerns ease and speed of maintenance or repair
Key rule: Deadline satisfaction is real-time performance; uptime, failure-free operation, and maintainability are different quality characteristics.
