Cache Memory

Cache memory, often referred to simply as cache, is a small but extremely fast type of memory used to temporarily store frequently accessed data and instructions for quick access by the CPU. Cache memory sits between the CPU and main memory (RAM) and helps reduce the average time to access data, thereby improving system performance. There are several levels of cache memory in a typical computer system, including L1 cache, L2 cache, and sometimes L3 cache. Each level of cache has different characteristics, such as size, latency, and access speed, with L1 cache being the smallest and fastest, located closest to the CPU. Cache memory plays a crucial role in speeding up data access and improving overall system responsiveness.
