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.

NAT
etwork 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.
AT 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.
Network
A network consists of a collection of two or more
devices, people, or components that communicate with
each other over physical or virtual media. The most
common types of network are:
LAN – (local area network): Computers are in close
distance to one another. They are usually in the same
office space, room, or building.
WAN – (wide area network): The computers are in
different geographic locations and are connected by
telephone lines or radio waves.
