VPN (Virtual Private Network) - A technique that allows two or more LANs to
be extended over public communication channels by creating private commu-
nication subchannels (tunnels). Effectively, these LANs can use a WAN as a
single large "virtually private" LAN. This removes the need to use leased lines
for WAN communications through secure use of a publicly available WAN
(such as the Internet). Examples of VPN technology are: PPTP (Point to Point
Tunneling Protocol), L2TP (Layer 2 Tunneling Protocol), and IPSec (Internet
Protocol Security).

WAN (Wide Area Network)- A communications network that covers a rela-
tively large geographic area, consisting of two or more LANs. Broadband com-
munication over the WAN is often through public networks such as the tele-
phone (DSL) or cable systems, or through leased lines or satellites. In its most
basic definition, the Internet could be considered a WAN.
