SMTP
Simple Mail Transfer Protocol
The SMTP
Protocol is part of the TCP/IP protocol family. It regulates the exchange of
electronic mail on the Internet . Your Internet Service Provider provides you with access
to an SMTP server.
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 (fixed) IP address
A static (or fixed)
IP address is assigned to a network component manually during
network configuration. Unlike a Dynamic IP address , a static (fixed) IP address never
changes.
Subnet
A 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 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 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.
Switch
A switch, like a
Hub , is an element used to link different network segments or
components. Unlike a hub however, the switch has its own intelligence that enables it
to forward packets to only that subnet or network component they are meant for.

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 foundation for each
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.
