Cache memory is the fastest and highest-performing type of memory in a computer system. It is a small-sized, high-speed memory unit located very close to or even inside the CPU. Cache memory temporarily stores data and instructions that the CPU uses frequently, reducing the time it takes to access this data compared to fetching it from main memory (RAM) or other storage devices.

Because of its proximity to the CPU and its high access speed, cache memory plays a crucial role in improving the system's overall performance. It helps the CPU avoid delays when executing tasks, especially when processing loops or repeatedly accessed instructions.
