Cache memory plays a crucial role in enhancing the performance of a computer by providing high-speed data access to the CPU. It is a small, high-speed storage area located close to the CPU that stores frequently accessed data and instructions. By keeping this data readily available, cache memory reduces the time the CPU spends waiting for data to be retrieved from the slower main memory (RAM). This speeds up processing and improves the overall efficiency of computing tasks.

Unlike other types of storage such as hard drives or SSDs, cache memory is designed specifically for fast access and is volatile, meaning it loses its contents when the power is turned off. Its primary function is to temporarily hold data that the CPU is most likely to reuse, making it critical to the speed and efficiency of computing processes.
