Glossary
SMTP
Simple Mail Transfer Protocol. The SMTP protocol is a
TCP/IP
protocol and regulates the
exchange of electronic post on the Internet. Your
Provider
provides you with access to
an SMTP server.
Subnet
A subnet divides a network into smaller units.
Subnet mask
The subnet mask determines how many parts of the IP addresses of a network represent
the network number and how many parts represent the network component number.
If the subnet mask in a network is 255.255.255.0, for example, this means that the first
three parts of the
IP address
make up the network number and only the last part can be
used to assign network component numbers. The first three parts of the IP address of
all network components are in this case always the same.
Switch
A switch is a central distributor in a wired network, which, unlike a hub, provides intel-
ligent distribution of data transfer. The switch only ever forwards a data packet to the
subnet or network component the data packet is intended for. Unnecessary transfer of
data in the network thus avoided.
TAE
Telecommunications connecting unit (German: Telekommunikations-Anschlussein-
heit). Connector for connecting analogue telecommunications devices. F for phone, N
for additional devices such as fax or answer machines.
TCP
Transmission Control Protocol. TCP is part of the
TCP/IP
protocol family. TCP handles data
transport between communication partners (applications). TCP is a session-based trans-
mission protocol, i.e. it sets up, monitors and terminates a connection for transporting
data.
TCP/IP
Transmission Control Protocol/Internet Protocol. Protocol family on which the Internet
is based. IP forms the basis of each PC to PC 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. In order to access the Internet from a PC, TCP/IP must be set up on the PC.
Uplink
Data that your Gigaset SX682 WiMAX forwards from your PC or local network to exter-
nal sites (e.g. to the Internet).
URL
Universal Resource Locator. Globally unique address of a domain on the Internet, e.g.
http://www.siemens.com.
