Caches in CPU architecture

Caches in CPU architecture are small, fast memory areas located close to the processor that temporarily hold recent or frequently accessed data and instructions. They reduce the time it takes for the CPU to retrieve information from the main memory, improving overall speed and efficiency. Think of it like a workspace where the CPU keeps important tools nearby, so it doesn't have to go back to a distant storage room every time it needs something. By minimizing delays, caches help the CPU perform tasks more quickly and efficiently.
