    Solution

    Cache memory is RAM that a microprocessor can access faster than it can access regular RAM. It is often tied directly to the CPU and is used to cache instructions that are accessed a lot. A RAM cache is faster than a disk-based one, but cache memory is faster than a RAM cache because it's close to the CPU.
