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 transfer proto-
col, i.e. it sets up, monitors and terminates a connection for transferring data.

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.
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 data packets, so-called datagrams, are
sent as a Broadcast. 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 on the network automatically.
URL
Universal Resource Locator
Globally unique address of a domain on the Internet.
VCI
Virtual Channel Identifier
Part of an address in an ATM network.
Encryption
Encryption protects confidential information against unauthorised access. With an
encryption system, data packets can be sent securely over a network. The Gigaset
SX553 WLAN dsl offers
WEP
encryption and
WPA
for secure data transfer over wireless
networks.
