NIS: Network Information Service
Network Information Service (NIS), previously known as Yellow Page protocol, is a directory service used for name look-up and general table enumeration. Each NIS database consists of key-value pairs, maps, and domains. NIS defines a set of key-value pairs as a map. Each map belongs to a domain that is a category of maps. This hierarchy of key-value pairs, maps, and domains provides a generic structure for modeling a database of information. An optional component to a NIS server database implementation is the NIS binder (YPbind) server. NIS uses YPbinder servers to provide addressing information about NIS database servers to potential clients.
