PPT-Distributed Hash Tables Distributed Hash Table

A common approach is to use a Distributed Hash Table DHT to organize nodes Traditional hash functions convert a key to a hash value which can be used as an index into a hash table Keys are unique. p p Conjunction both statements must be true Two True statements will result in a True T Any other combination will produce a False F p q p q Disjunction If eitheror both statements are true the entire statement is true One True will result in a T DSC340. .
