Digital cache

A digital cache is a small, fast storage area close to a computer's processor that temporarily holds data and instructions the system uses frequently. Think of it as a quick-access workspace, reducing the time needed to fetch information from the main memory (RAM). When the processor needs data, it first checks the cache, which speeds up processing. If the data isn't there, it retrieves it from the slower main memory and stores a copy in the cache for future use. This mechanism improves overall performance by minimizing delays in data access.
