Subnet
A subnet divides a network into smaller units.
Subnet mask
The subnet mask determines how many parts of a PC'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. That means the first three parts of the IP address form the network
address and only the final part is used to assign PC addresses. The first three parts of the
IP addresses of all network components are in this case always the same.
Switch
Like a hub, a switch is an element that links different network segments or components.
Unlike a hub, however, the switch has its own intelligence that enables it to forward
packets only to the subnet or network component for which they are intended.

TKIP
Temporal Key Integrity Protocol
TKIP is a further development of WEP encryption. Like WEP, TKIP encryption is based on
the RC4 encryption algorithm. However, TKIP generates new keys after every 10-kbyte
packet, thus meeting higher security requirements.
UDP
User Datagram Protocol
UDP is a protocol from the TCP/IP protocol family that 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, 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.
WAN
Wide Area Network
A WAN is a wide area network, which is not restricted to one particular area. The Internet
is the most frequently used WAN. A WAN is run by one or more public providers to ena-
ble private access. You access the Internet via an Internet provider.
WEP
Wired Equivalent Privacy
WEP is a security protocol defined in the
standard. It is used to protect wire-
less transmission in a
against unauthorised access through
of the data
transmitted.
