Detailed explanation-1: -Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory. The fastest portion of the CPU cache is the register file, which contains multiple registers.
Detailed explanation-2: -Types of cache memory L1 cache, or primary cache, is extremely fast but relatively small, and is usually embedded in the processor chip as CPU cache. L2 cache, or secondary cache, is often more capacious than L1.
Detailed explanation-3: -Cache memory is faster than main memory. It consumes less access time as compared to main memory. It stores the program that can be executed within a short period of time. It stores data for temporary use.
Detailed explanation-4: -Level 1 (L1) is the fastest type of cache memory since it is smallest in size and closest to the processor. Level 2 (L2) has a higher capacity but a slower speed and is situated on the processor chip. Level 3 (L3) cache memory has the largest capacity and is situated on the computer that uses the L2 cache.
Detailed explanation-5: -Cache memory is used to reduce the average memory access times. This is done by storing the data that is frequently accessed in main memory addresses therefore allowing the CPU to access the data faster. This is due to the fact that cache memory can be read a lot faster than main memory.
