Cache Memory

Cache memory is a small, high-speed memory that stores frequently accessed data and instructions closer to the processor, allowing the processor to access them quickly. It acts as a buffer between the CPU and main memory, reducing the average time to access data from main memory. When the processor needs data, it first checks the cache memory. If the data is found in the cache, it is called a cache hit, and the processor can access it quickly. If the data is not found in the cache, it is called a cache miss, and the processor must access it from main memory, which takes more time. Cache memory is an essential component of modern computer systems, as it helps to improve the overall performance of the system.
