native VLAN
Cisco switches all have a native VLAN called VLAN 1.
This cannot be deleted or changed in any way. All switch ports are in
VLAN 1 by default.
NBP
Name Binding Protocol: In AppleTalk, the transport-level protocol
that interprets a socket client's name, entered as a character string, into
the corresponding DDP address. NBP gives AppleTalk protocols the
capacity to discern user-defined zones and names of mechanisms by
showing and keeping translation tables that map names to their corre-
sponding socket addresses.
neighboring routers
Two routers in OSPF that have interfaces to a
common network. On networks with multiaccess, these neighboring routers
are dynamically discovered using the Hello protocol of OSPF.
NetBEUI
NetBIOS Extended User Interface: An improved version of the
NetBIOS protocol used in a number of network operating systems including
LAN Manager, Windows NT, LAN Server, and Windows for Workgroups,
implementing the OSI LLC2 protocol. NetBEUI formalizes the transport
frame not standardized in NetBIOS and adds more functions. See also: OSI.
NetBIOS
Network Basic Input/Output System: The API employed by
applications residing on an IBM LAN to ask for services, such as session ter-
mination or information transfer, from lower-level network processes.
NetView
A mainframe network product from IBM, used for monitoring
SNA (Systems Network Architecture) networks. It runs as a VTAM (Virtual
Telecommunications Access Method) application.
NetWare
A widely used NOS created by Novell, providing a number of
distributed network services and remote file access.
network access layer
Bottom layer in the Internet Protocol suite that
provides media access to packets.
network address
Used with the logical network addresses to identify the
network segment in an internetwork. Logical addresses are hierarchical
in nature and have at least two parts: network and host. An example of a
hierarchical address is 172.16.10.5, where 172.16 is the network and 10.5 is
the host address.
