SSID

Service Set Identifier

The SSID is used to identify the stations in a wireless network (WLAN). All wireless network components with the same SSID form a common network. The SSID can be assigned by the network operator.

Static IP address

A static IP address is assigned to a network component manually during network con- figuration. Unlike a Dynamic IP address, a static (fixed) IP address never changes.

SubnetA subnet divides a network into smaller units.Subnet mask

The subnet mask determines how parts of the IP addresses of a network represent the network number and how many the computer number.

The subnet mask in a network administered by the Gigaset SE551 WLAN dsl/cable is always 255.255.255.0. That means the first three parts of the IP address form the network number and the final part is used for assigning computer numbers. The first three parts of the IP address of all network components are in this case always the same.

Super G

Super G is an extension of IEEE 802.11g. Channel bundling doubles the maximum transfer rate to 108 Mbps. Unlike other technologies (e.g. 125 Mbps technology) which work by compressing data, here the transfer rate is actually doubled. If data is already compressed (ZIP, RAR, MP3, MPEG etc.) data compression offers no significant improve- ments.

Switch

A switch, like a Hub, is an element used to link different network segments or compo- nents. Unlike a Hub however, the Switch has its own intelligence that enables it to forward packets to only the subnet or network component they are meant for.

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.
