What is a network operating system (NOS): A network operating system (NOS) is a computer operating system (OS) that's designed primarily to support workstations, PCs and, in some instances, older terminals that are connected on a local area network (LAN). The software behind a NOS enables multiple devices within a network to communicate and share resources with each other.

This can include such devices as PCs, printers, file servers and databases connected to a local network. The role of the NOS is to provide basic network services and features that support multiple input requests simultaneously in a multiuser environment. Types of network operating systems: There are two basic types of network operating systems: Peer-to-peer (P2P) network OSes let users share network resources saved in a co
