Glossary
subnet mask
The subnet mask indicates which part of an IP address (see
glossary) is the network address and which the address of
the computer. The network address defines what is called the
subnet.
subnetwork
A local IP network can consist of one subnetwork or be divid-
ed into multiple subnetworks. The division into subnetworks
is performed when the local IP network is configured. The
subnetworks of a local IP network are also IP networks (see
glossary).
switch
A switch is a device that connects multiple network devices
with each other, for instance through an Ethernet.
In contrast to a hub, a switch can establish direct connections
between the connected devices. This makes it possible to
send data packets directly to specific recipients.
The entire data throughput is at the disposal of every con-
nected device.
TCP/IP
short for Transmission Control Protocol / Internet Protocol
TCP/IP is the “language” of the Internet. TCP/IP is used to re-
fer to a suite of protocols used for data communication over
the Internet. TCP and IP are the network and transport proto-
cols underlying most Internet services, including file transfer
(FTP) and e-mail communication (SMTP). TCP/IP is available
for practically all computer systems. TCP/IP thus offers the
advantage of trouble-free communication between otherwise
incompatible networks and systems.
