Cache memory is a small, high-speed memory buffer that stores frequently accessed data and instructions in a computer's CPU. The primary role of cache memory in computational architecture is to reduce access time and speed up processing by storing frequently used data in a faster and more easily accessible location. By keeping important data close at hand, cache memory can eliminate the need for the CPU to constantly access slower memory, which can improve overall system performance and reduce lag times. In essence, cache memory acts as a bridge between the CPU and the main memory, ensuring that data can be accessed quickly and efficiently.
