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 com-

munication partners (applications). Unlike

TCP

, UDP is a non-session based protocol. 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

.

Virtual server
A virtual

Server

provides a service on the

Internet

, that runs not on itself, but on another

network component. The Gigaset SE551 WLAN dsl/cable can be configured as a virtual
server. It will then direct incoming calls for a service via

Port Forwarding

directly to the

appropriate

Port

of the network component in question.

VoIP
Voice over IP
See

Internet telephony

WAN
Wide Area Network
A WAN is a network that is not restricted to one particular area, such as the

Internet

.

A WAN is run by one or more public providers to enable private access. You access the
Internet via an

Internet Provider

.
