Memory is the cognitive process of acquiring, encoding, storing, retaining, and retrieving information, experiences, and skills. It operates in three main stages—encoding (input), storage (retention), and retrieval (accessing)—and is essential for learning and daily functioning. Key types include sensory, short-term (working), and long-term memory.
