UDP (User Datagram Protocol) - A communications method (protocol) that

offers a limited amount of service when messages are exchanged between com-

puters in a network that uses the Internet Protocol (IP). UDP is an alternative

to the Transmission Control Protocol (TCP) and, together with IP, is sometimes

referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the

Internet Protocol to actually get a data unit (called a datagram) from one com-

puter to another. Unlike TCP, however, UDP does not provide the service of

dividing a message into packets (datagrams) and reassembling it at the other

end. Specifically, UDP doesn't provide sequencing of the packets that the data

arrives in. This means that the application program that uses UDP must be able

to make sure that the entire message has arrived and is in the right order.

Network applications that want to save processing time because they have very

small data units to exchange (and therefore very little message reassembling to

do) may prefer UDP to TCP.

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.

Virtual Server - Multiple servers that appear as one server, or one system

image, to the operating system or for network administration

WAN - A communications network that covers a wide geographic area, such as

a state or country.

WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-

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, under Windows 95, 98, and Millennium, for configuring networks with

static IP addresses.
