NIC
Network Information Center. Originally there was only one, located at SRI International and tasked to serve the ARPANET (and later DDN) community. Today, there are many NICs, operated by local, regional, and national networks all over the world. Such centers provide user assistance, document service, training, and much more.
NIDI

NIU
Network Interface Unit. Basically repeaters, these boxes connect CSU/DSU modems and raw T1 serial lines. They have 3 basic functions: protecting us from the phone company (T1 lines carry 130 volts), repeating the signal, and loopbacking back the signals. They also provide everyone with a known demarcation point for finger pointing purposes.

NMS
Network Management Station or System. The system responsible for managing a (portion of a) network. The NMS talks to network management agents, which reside in the managed nodes, via a network management protocol. SunNet Manager, Cabletron Spectrum, HP OpenView and IBM NetView/6000 are NMSs. See agent.
