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 SBG1000 LAN computers are invisible on the Internet. | |
| If NAT is enabled on the Gateway page, there is a | |
| 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 | |
| permanently saved in its ROM. |
|
node | On a LAN, a generic term for any network device. |
|
| On an HFC network, the interface between the | |
| subscriber locations. A node is typically located in the subscriber neighborhood. | |
noise | Random spurts of electrical energy or interface. May produce a | |
| picture. |

O
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. | |
