GlossarySMTPSimple Mail Transfer ProtocolThe SMTP Protocol is part of the TCP/IP protocol family. It regulates the exchange ofelectronic mail on the Internet. Your Internet Service Provider provides you with accessto an SMTP server.SSIDService Set IdentifierThe SSID is used to identify the stations in a wireless network (WLAN). All wirelessnetwork components with the same SSID form a common network. The SSID can beassigned by the network operator.Static (fixed) IP addressA static (or fixed) IP address is assigned to a network component manually duringnetwork configuration. Unlike a Dynamic IP address, a static (fixed) IP address neverchanges.SubnetA subnet divides a network into smaller units.Subnet maskThe subnet mask determines how parts of the IP addresses of a network represent thenetwork number and how many the computer number.The subnet mask administered by the Gigaset SE505 dsl/cable is always 255.255.255.0.That means the first three parts of the IP address form the network number and the finalpart is used for assigning computer numbers. The first three parts of the IP address ofall network components are in this case always the same.SwitchA switch, like a Hub, is an element used to link different network segments orcomponents. Unlike a hub however, the switch has its own intelligence that enables itto forward packets to only that subnet or network component they are meant for.See also: Bridge, Hub, Router, GatewayTCPTransmission Control ProtocolThe TCP Protocol is part of the TCP/IP protocol family. TCP handles data transportbetween communication partners (applications). TCP is a session-based transmissionprotocol, i.e. it sets up, monitors and terminates a connection for transporting data.See also: UDPTCP/IPProtocol family on which the Internet is based. IP forms the foundation for eachcomputer-to-computer connection. TCP provides applications with a reliabletransmission link in the form of a continuous data stream. TCP/IP is the basis on whichservices such as WWW, Mail and News are built. There are other protocols as well.131
