Network Operating system or NOS is an OS that allows a system to connect to a network. Such as Novell and Artisoft's LANtastic. In the old days of DOS networking was not a function of the Client OS, you have to also load the NOS to get connected. Now that most Client OS's imbed network connectivity the term is now seldom used.
