This refers to a high-speed memory that a processor can access more quickly than RAM. Frequently used instructions are stored in cache since they can be retrieved more quickly improving the overall performance of the computer. Level 1 (L1) cache is located on the processor; Level 2 (L2) is located between the processor and RAM. Cache memory is very expensive and thus the size of this memory in the computer relative to the primary and secondary memory is very small.
