Search Engine Hash Table - Hash table - wikipedia, In computing, a hash table (hash map) is a data structure that implements an associative array abstract data type, a structure that can map keys to values.a hash table uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found.. ideally, the hash function will assign each key to a unique bucket, but most hash table designs employ an. Distributed hash table - wikipedia, A distributed hash table (dht) is a class of a decentralized distributed system that provides a lookup service similar to a hash table: (key, value) pairs are stored in a dht, and any participating node can efficiently retrieve the value associated with a given key. keys are unique identifiers which map to particular values, which in turn can be anything from addresses, to documents, to.
