    Network Operating System (NOS)
    NOS is software that controls the execution of network programs and modules. Structurally, networking software comprises multiple modules, most residing in network servers, but some must be installed in each terminal/station that can access network resources. Peer-to-peer NOSs permit any terminal/station to act as a resource server or a client, and can be based on Microsoft's Disk operating system (MS DOS) designed for IBM and compatible PCs. Since MS DOS is not designed to run multiple programs and respond to many simultaneous users, most NOSs designed for large networks with dedicated servers/superservers, have a multitasking and multi- user architecture. Advanced NOS products support network management, diagnostics, and administration, as well as, primary server, client, de vice and external network driver functions.
