Explanation:
Detailed explanation-1: -L1 cache, or primary cache, is extremely fast but relatively small, and is usually embedded in the processor chip as CPU cache .
Detailed explanation-2: -At the highest level, the most frequently used information-say, the instructions in a loop which execute repeatedly-is stored directly on a special section of the processor chip, called Level 1 (L1) cache. This is the fastest memory of all.
Detailed explanation-3: -The cache can only load and store memory in sizes a multiple of a cache line. Caches have their own hierarchy, commonly termed L1, L2 and L3. L1 cache is the fastest and smallest; L2 is bigger and slower, and L3 more so.
