+A **hash table** is a fundamental [data structure](/wiki/data_structure) that efficiently maps keys to values. It uses a [hash function](/wiki/hash_function) to compute an index, allowing for rapid data retrieval and insertion, often in near-constant time. This structure is central to many high-performance applications.
