ITPEC IP October 2020 Question 12
ITPEC IP October 2020 — Question 12 of 100
The number of CPU cores is the number of processing cores built into the processor, giving terms such as dual-core and quad-core. Multiple cores can execute work in parallel when software and workload permit it.
Answer (b)
Why not others:
- processing speed is not inversely proportional to clock frequency; all else equal, more cycles per second can increase work rate
- a smaller supported thread count does not inherently make processing faster
- primary cache is closer to the core than secondary cache, not the reverse
Key rule: Cores are physical processing units; threads are execution streams, clock frequency is cycles per second, and cache is fast nearby memory.
