UTP - Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electro-
magnetic induction between pairs of wires, two insulated copper wires are
twisted around each other. Each signal on twisted pair requires both wires.
Since some telephone sets or desktop locations require multiple connections,
twisted pair is sometimes installed in two or more pairs, all within a single
cable.
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 the Internet as
a single large "virtually private" LAN. This removes the need to use leased
lines for Internet communications. 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
communication over the WAN is often through public networks such as the
telephone (DSL) or cable systems, or through leased lines or satellites. In its
most basic definition, the Internet could be considered a WAN.
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-
bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard.
WINIPCFG - Configuration utility based on the Win32 API for querying,
defining and managing IP addresses within a network. A commonly used util-
ity for configuring networks with static IP addresses.
