Cache Memory or High Speed Buffer

Cache Memory

Cache memory is high-speed memory that holds the most recent data and instructions that have been loaded by the CPU.

Cache is located directly on the CPU or between the CPU and RAM, making it faster than normal RAM.

CPU-resident cache is called Level-1 (L1) cache. External cache is called Level-2 (L2) cache.

The amount of cache memory has a tremendous impact on the computer's speed.
