Network Operating System

The OS specializes in network devices such as a router, switch, or firewall. The OS manages these network resources. The OS supports workstations, Personal Computers (PCs), older terminals connected on a Local Area Network (LAN).

Examples of Network OSs are Microsoft Windows Server 2003, Microsoft Windows Server 2008, UNIX, Linux, Mac OS X, etc.
