ITPEC IP April 2021 — Question 16 of 100
Parallel processing divides work into units that can execute simultaneously on multiple CPUs or cores. When tasks are sufficiently independent, concurrent execution shortens total elapsed time or increases throughput, though coordination and synchronization add overhead.
Answer (a)
Why not others:
- grouping related processes does not define simultaneous execution
- separating server business logic from client UI is client-server processing
- rapidly sharing one CPU among applications is time-sharing, which creates apparent concurrency
Key rule: True parallelism performs multiple operations at the same time using multiple processing resources.
