ITPEC IP April 2022 Question 10
ITPEC IP April 2022 — Question 10 of 100
A dual-core processor contains two processor cores in one integrated-circuit package, allowing the cores to execute separate instruction streams concurrently. The operating system can schedule different threads on the two cores, improving throughput for parallel workloads while the cores share some package resources.
Answer (d)
Why not others:
- (a) describes a dual-boot computer with two operating systems
- (b) describes a dual-monitor display configuration
- (c) describes dual-channel memory, which accesses matched memory modules concurrently to increase bandwidth
Key rule: Dual core refers to two execution cores in one processor package; it does not mean two operating systems, displays, or memory channels.
