Static IP address
A static
IP address is assigned to a network component manually during network
configuration. Unlike a Dynamic IP address , a static IP address never changes.
Subnet
A subnet divides a network into smaller units.
Subnet mask
The subnet mask determines how many parts of a network's
IP address represent the
network address and how many parts represent the PC address.
The subnet mask in a network administered by the Gigaset SE366 WLAN is always
255.255.255.0. This means that the first three parts of the IP address form the network
address and only the final part is used for the PC address. In this case, the first three
parts of the IP address of all network components are therefore always the same.
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.

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.
