What is the difference between "L1", "L2", and "L3" cache?
Correct! Well done.
Incorrect.
The correct answer is A) L1 is the smallest and fastest cache, located closest to each CPU core; L2 is larger and slightly slower; L3 is the largest, slowest of the caches, and often shared across cores
A
Correct Answer
L1 is the smallest and fastest cache, located closest to each CPU core; L2 is larger and slightly slower; L3 is the largest, slowest of the caches, and often shared across cores
Explanation
Cache hierarchies balance speed and size — L1 is tiny but extremely fast and per-core, L2 is larger but slower, and L3 is the largest and slowest of the on-chip caches, often shared among all cores to reduce main memory access.
