Glossary
Switch
Like a Hub, a switch is an element used to link different network segments or compo-
nents. Unlike a hub, however, a switch has its own intelligence, which enables it to for-
ward packets only to the subnet or network component for which they are intended.

TCP
Transmission Control Protocol
The TCP Protocol is part of the TCP/IP protocol family. TCP handles data transport
between communication partners (applications). TCP is a session-based transmission
protocol, i.e. it sets up, monitors and terminates a connection for transporting data.
See also UDP
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.
TKIP
The Temporal Key Integrity Protocol (TKIP) is part of the IEEE 802.11i standard and is
used to encrypt data in wireless networks.
UDP
User Datagram Protocol
UDP is a Protocol from the TCP/IP protocol family, which handles data transport between
two communication partners (applications). Unlike TCP, UDP is a non-session based pro-
tocol. It does not establish a static connection. The data packets, so-called datagrams,
are sent as a Broadcast. The recipient alone is responsible for making sure the data is
received. The sender is not notified about whether or not it is received.
UPnP
Universal Plug & Play
UPnP technology is used to spontaneously link 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 on the network automatically.
URL
Universal Resource Locator
Globally unique address of a domain on the Internet.
