Correct Answer: cache

Solution : The correct answer is cache .

Cache memory is a chip-based computer component that makes retrieving data from the computer's memory more efficient. It acts as a temporary storage area that the computer's processor can retrieve data from easily.

To be close to the processor, cache memory needs to be much smaller than the main memory. Consequently, it has less storage space. It is also more expensive than main memory, as it is a more complex chip that yields higher performance.
