Network Information System (abbreviation: NIS) is an information system for managing networks, such as electricity network, water supply network, gas supply network, telecommunications network.

NIS may manage all data relevant to the network, e.g.- all components and their attributes, the connectivity between them and other information, relating to the operation, design and construction of such networks.

NIS for electricity may manage any, some or all voltage levels- Extra High, High, Medium and low voltage. It may support only the distribution network or also the transmission network.

NIS may be built on top of a GIS (Geographical information system).

NIS is used for centralised Authentication. NIS shares all NIS users' home directories using NFS and we can access any NIS users from any client in the network.
