Why does a memory hierarchy improve overall system performance?
Why does a memory hierarchy improve overall system performance?
a)
It stores all data only in registersb)
It combines small fast memory with larger slower memoryc)
It makes every memory level equally fastd)
It removes the need for RAMExplanation
The hierarchy exploits locality so a small amount of fast memory can serve most CPU accesses.Related questions
