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.
TR-069
TR-069 is a technical directive that simplifies the automatic
configuration of Internet access devices like the FRITZ!Box.
TR-069 describes the remote configuration of Internet access
devices. In remote configuration the access and account data
are automatically transmitted to the FRITZ!Box by the Internet
provider. These may include the account data for the Internet
connection, Internet telephone numbers and login data for In-
ternet telephony, or both.
The Internet Service Provider saves the data to be transmitted
on what is called an Auto Configuration Server (ACS). When
the FRITZ!Box is connected with the broadband line (for in-
stance, DSL), the data can be transferred automatically from
the ACS to the FRITZ!Box. This relieves the user of the task of
manually setting up the Internet connection and/or Internet
telephone numbers in the FRITZ!Box.
