What is the purpose of cache memory in a CPU? To store the operating system To increase the clock speed To cool the CPU To store frequently used data for quick access

The purpose of cache memory in a CPU is to store frequently used data for quick access. Cache memory is a small, high-speed memory unit located within the CPU. It acts as an intermediary between the main memory (RAM) and the CPU, storing copies of frequently accessed data and instructions. When the CPU needs to access data, it first checks the cache memory to see if the data is already stored there. If it is, the CPU can retrieve it quickly, without having to access the slower main memory. This significantly increases the overall speed and efficiency of the CPU, as it reduces the time it takes to access frequently used data.
