ITPEC IP April 2026 Question 14
ITPEC IP April 2026 — Question 14 of 100
Divide work into simultaneously executable units and run them on multiple CPUs — this is parallel processing.
Parallel processing reduces elapsed time by splitting a task into parts that can execute at the same moment on different processors or cores. The parts may later synchronize or combine their results, but their overlapping execution is the defining feature.
Answer (a)
Why not others:
- (b) describes grouping related processes, not executing task portions simultaneously
- (c) describes client-server processing, where responsibilities are divided between client and server
- (d) describes time sharing or multitasking on one CPU; the CPU alternates short time slices, so the work is not physically simultaneous
Key rule: Parallelism means simultaneous execution using multiple processing resources; concurrency on one CPU may only interleave tasks over time.
