what are some resources that an nos provides
Network operating system - wikipedia Network operating system Jump to : navigation , search The term network operating system is used to refer to two rather different concepts : A specialized operating system for a network device such as a router , switch or firewall . An operating system oriented to computer networking , to allow shared file and printer access among multiple computers in a network , to enable the sharing of data , users , groups , security , applications , and other networking functions , typically over a local area network ( LAN ) , or private network . This sense is now largely historical , as common operating systems generally now have such features included . Contents ( hide ) 1 Network device operating systems 2 Historic network operating systems 2.1 Peer - to - peer 2.2 Client - server 3 See also 4 References 5 External links Network device operating systems ( edit ) Network operating systems can be embedded in a router or hardware firewall that operates the functions in the network layer ( layer 3 ) . Examples : JUNOS , used in routers and switches from Juniper Networks Cisco Internetwork Operating System ( IOS ) IPOS , used in routers from Ericsson FortiOS , used in Fortigates from Fortinet TiMOS , used in routers from Alcatel - Lucent Versatile Routing Platform ( VRP ) , used in routers from Huawei RouterOS , software which turns a PC or MikroTik hardware into a dedicated router ZyNOS , used in network devices made by ZyXEL . Extensible Operating System used in switches from Arista ExtremeXOS ( EXOS ) , used in network devices made by Extreme Networks Embedded Linux , in distributions like Openwrt and DD - WRT which run on low - cost platforms such as the Linksys WRT54G Open source network operating system examples : Cumulus Linux distribution , which uses the full TCP / IP stack of Linux . Dell Networking Operating System ( DNOS ) is the new name for the operating system running on switches from Dell Networking ; it will run atop NetBSD Open Network Operating System ( ONOS ) PicOS , Linux - based OpenFlow - supporting switching operating system from made by Pica8 VyOS , an open source fork of the Vyatta routing package OpenSwitch Linux Network Operating System from Hewlett - Packard . Historic network operating systems ( edit ) Early microcomputer operating systems such as CP / M , DOS and classic Mac OS were designed for one user on one computer . As local area network technology became available , two general approaches to handle sharing arose . Peer - to - peer ( edit ) In a peer - to - peer network operating system users are allowed to share resources and files located on their computers and access shared resources from others . This system is not based with having a file server or centralized management source . A peer - to - peer network sets all connected computers equal ; they all share the same abilities to use resources available on the network . Examples : AppleShare used for networking connecting Apple products . LANtastic supporting DOS , Microsoft Windows , and OS / 2 computers Windows for Workgroups used for networking peer - to - peer Windows computers . The advantages include : Ease of setup Less hardware needed , no server need be acquired The disadvantages include : No central location for storage Less security than the client -- server model Client - server ( edit ) Network operating systems can be based on a client -- server model ( architecture ) in which a server enables multiple clients to share resources . Client - server network operating systems allow networks to centralize functions and applications in one or more dedicated file servers . The server is the center of the system , allowing access to resources and instituting security . The network operating system provides the mechanism to integrate all the components on a network to allow multiple users to simultaneously share the same resources regardless of physical location . Examples : Novell NetWare Windows Server Banyan VINES The advantages include : Centralized servers are more stable . Security is provided through the server . New technology and hardware can be easily integrated into the system . Hardware and the operating system can be specialized , with a focus on performance . Servers are able to be accessed remotely from different locations and types of systems . The disadvantages include : Buying and running a server raises costs . Dependence on a central location for operation . Requires regular maintenance and updates .
