ITPEC IP April 2021 — Question 10 of 100
A multi-core processor contains multiple processing cores within one CPU, allowing different work to execute concurrently. Parallel execution can increase throughput when software divides its work into independent threads that the cores can run simultaneously.
Answer (d)
Why not others:
- redundant processors performing identical work describe fault-tolerant duplication
- four cores do not guarantee four times the performance of two because workloads and overhead limit parallelism
- temporarily raising clock frequency describes dynamic frequency boosting
Key rule: Multi-core means several execution cores in one processor package, not automatic linear performance scaling.
