Local Area Network (LAN)
A computer network that spans a
relatively small area. Most LANs are
confined to a single building or group
of buildings. However, one LAN can
be connected to other LANs over any
distance. A system of LANs
connected in this way is called a wide
area network (WAN)
MAC Address
Short for Media Access Control
Address, a hardware address that
uniquely identifies each node of a
network.
NAT
Short for Network Address
Translation, a routing protocol that
allows global IP Addresses to be
translated into multiple private IP
Addresses for use on internal LAN
networks. The explosion in the use of
the Internet has created a critical
problem for the Internet Assigned
Numbers Authority (IANA) which is
in charge of assigning IP Addresses to
Internet users, ISPs etc. NAT is a
technology that has been introduced
to help maximize the utilization of
assigned IANA and global IP
Addresses.
Network Protocol
Network protocols encapsulate and
forward data packets from one
interface to another.
PAP/CHAP
Short for Password Authentication
Protocol and Challenge Handshake
Authentication Protocol. Most ISPs
use either one for user identification.
If your ISP doesn't support these two
protocols, contact them for an
authentication script.

PPP
Short for Point-to-Point Protocol, a
communications protocol for
transmitting information over standard
telephone lines between devices from
different manufacturers.
PPPoE
Short for PPP over Ethernet, relying
on two widely accepted standards,
Ethernet and the Point-to-Point
Protocol. PPPoE is a communications
protocol for transmitting information
over the Ethernet between devices
from different manufacturers.
PPTP
The acronym of Point to Point
Tunnelling Protocol, PPTP
encapsulates the packet for
transmission over the Internet. It
creates a private "tunnel" through the
large public network to have similar
security of private network without
actually leasing a private line. PPTP
is normally used for VPN
connections.
Protocol
An agreed format for transmitting,
sending and receiving data between
two devices.
Roaming
The ability for a wireless device to
move from one access point's range to
another without losing the connection.
Router
An Internet device that routes
requests for information to other
routers until the information's location
is found and the data can be
transmitted back to the origin of the
request.
