Why is cache memory useful even though it is very small?

Answer and explanation

Correct answer: It keeps frequently used data close to the processor

Cache memory is small but usually much faster for the processor to access than main memory. It stores frequently used instructions and data, or information likely to be needed soon, close to the CPU. This reduces repeated waits for slower RAM and can improve processing speed. Cache is not a complete file-backup system, a network connector, or a printer-ink-saving device.
