Cache memory is known for its low capacity and high speed. It is much smaller than the main memory (RAM) but operates at a much faster speed, providing the CPU with quick access to frequently used data.
Cache is designed to store only the most frequently accessed data and instructions, rather than all data in a system. Cache memory operates at a very high speed, much faster than both main memory and storage devices. The speed of cache memory is crucial because it is located closer to the CPU and is used to supply the CPU with data at speeds that match the CPU’s processing speed.
