Server
A server makes services available to other network components (clients). The term

rotocol. The SMTP protocol is a

the exchange of electronic post on the Internet. Your
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 repre-
sent the network number and how many parts represent the network component num-
ber.
If the subnet mask in a network is 255.255.255.0, for example, this means that the first
three parts of the
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

is based. IP forms the basis of each PC to PC connection.
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 pro-
tocols as well. In order to access the Internet from a PC, TCP/IP must be set up on the
PC.
