NAT
Network Address Translation is an Internet standard for a LAN to use one set of IP addresses for
internal traffic and a second set of IP addresses for external traffic. NAT provides some security
because the IP addresses of SBG940 LAN computers are invisible on the Internet.
If NAT is enabled on the Gateway page, there is a one-to-one mapping between each public IP
address and client IP address.
NAPT
Network Address Port Translation is the most common form of address translation between public and
private IP addresses. NAPT is a mapping of one public IP address to many private IP addresses.
If
NAPT is enabled on the Gateway page, one public IP address is mapped to an individual private
IP address for up to 245 LAN clients.
NEC
National Electrical Code (United States) — The regulations for construction and installation of
electrical wiring and apparatus, suitable for mandatory application by a wide range of state and local
authorities.
network
Two or more computers connected to communicate with each other. Networks have traditionally been
connected using some kind of wiring.
network driver
Software packaged with a NIC that enables the computer to communicate with the NIC.
network layer
Layer 3 in the OSI architecture that provides services to establish a path between open systems. The
network layer knows the address of the neighboring nodes, packages output with the correct network
address data, selects routes, and recognizes and forwards to the transport layer incoming messages
for local host domains.
NIC
A network interface card converts computer data to serial data in a packet format that it sends over the
LAN. A NIC is installed in an expansion slot or can be built-in. Every Ethernet NIC has a MAC address
permanently saved in its ROM.
node
On a LAN, a generic term for any network device.
On an HFC network, the interface between the fiber-optic trunk and coaxial cable feeders to
subscriber locations. A node is typically located in the subscriber neighborhood.
noise
Random spurts of electrical energy or interface. May produce a salt-and-pepper pattern on a television
picture.
ohm
A unit of electrical resistance.
OSI
The Open Systems Interconnection reference model is an illustrative model describing how data
moves from an application on the source host through a network to an application on the destination
host. It is a conceptual framework developed by ISO that is now the primary model for intercomputer
communications. OSI is a model
only
; it does not define a specific networking interface.
