Disk cache is a portion of a computer's main memory (RAM) that is used to store frequently accessed data from a disk drive. This speeds up data retrieval because accessing RAM is much faster than accessing a hard disk drive or solid-state drive. When the CPU needs data, it first checks the disk cache. If the data is present (a cache hit), it's retrieved quickly. If not (a cache miss), the data is fetched from the disk and also copied into the cache for future use.
