LAN Local Area Network a computer network that spans a relatively
small area sharing common resources. Most LANs are confined to a
single building or group of buildings.
N
NAT Network Address Translator generally applied by a router, that
makes many different IP addresses on an internal network appear
to the Internet as a single address. For routing messages properly
within your network, each device requires a unique IP address. But
the addresses may not be valid outside your network. NAT solves
the problem. When devices within your network request information
from the Internet, the requests are forwarded to the Internet under
the router’s IP address. NAT distributes the responses to the proper
IP addresses within your network.

connected by telephone lines or radio waves.
NWay Protocol A network protocol that can automatically negotiate the highest
possible transmission speed between two devices.
