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 enable private access. You access the Internet via an Internet provider.

WEP

Wired Equivalent Privacy

WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wireless transmission in a WLAN against unauthorised access through WAN of the data transmitted.
