nents. Unlike a hub however, the switch has its own intelligence that enables it to for-

ward packets to only the subnet or network component they are meant for.

TCP/IP

Protocol family on which the Internet is based. IP forms the basis for every computer-to-

computer connection. TCP provides applications with a reliable transmission link in the

form of a continuous data stream. TCP/IP is the basis on which services such as WWW,

Mail and News are built. There are other protocols as well.

UDP

User Datagram Protocol

UDP is a Protocol of the TCP/IP protocol family that handles data transport between two

communication partners (applications). Unlike TCP, UDP is a non-session based proto-

col. It does not establish a fixed connection. The recipient is responsible for making sure

the data is received. The sender is not notified about whether it is received or not.

UPnP

Universal Plug and Play

UPnP technology is used for the spontaneous linking of home or small office networks.

Devices that support UPnP carry out their network configuration automatically once

they are connected to a network. They also provide their own services or use services of

other devices in the network automatically.

URL

Vanity

The term vanity comes from the United States. Alphanumeric key-

pads on phones and other phone terminals allow you to represent

phone numbers as words so that they can be remembered more eas-

ily. Instead of a combination of digits, you select a combination of

letters.
