connected in this way is called a wide area network (WAN)
MAC Address
Short for Media Access Control Address and in 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 IAN and global IP Addresses.
Network Protocol
Network protocols encapsulate and forward data packets from one interface to another.
PAP/CHAP ISP

Protocol. Most ISPs use either one for user identification. If your ISP doesn’t support
these two protocols, contact your ISP 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. It’s a communications protocol for transmitting information
between devices from different manufacturers over an Ethernet.
PPTP
Short for Point to Point Tunneling Protocol, PPTP encapsulates the packet for
transmission over the Internet. It is similar to creating a private “tunnel” over a large
public network and has almost equal security to a private network without actually
leasing a private line.
Protocol
An agreed format for transmitting, sending and receiving data between two devices.
Roaming
The ability for a wireless device moving from one access poin
t
’s range to another without
losing the connection.
