G
Gateway A gateway designates and serves as the transition between two networks. A
gateway computer is a special computer that is connected to both networks.
This may require the implementation and use of different protocols. For ex-
ample, two LANs are connected by a gateway. All data from one network to
the other must pass through the gateway.
H
Home Network Home networks are local networks which enable computers and their periph-
erals to be interconnected and possibly shared. In addition, consumer elec-
tronics devices such as TVs, set-top boxes, etc., can be controlled via home
networks. A home network may be configured as a wired and/or wireless net-
work, where a wide range of different technologies such as Wi-Fi, USB or
wired Ethernet work together.
I
IAD IAD (integrated access device) refers to an xDSL modem with additional func-
tionality such as telephony.
IP address In a network that uses the TCP/IP protocol, each computer is identified by a
unique numeric address. Each IP address can occur once (i..e, must be unique)
within a network.
The Gateway 400 allows you to use network addresses in one of two possible
formats: the proven 32-bit legacy format Internet Protocol Version 4 (IPv4) or
the new 128-bit format Internet Protocol Version 6 (IPv6). Further details can
be found in the section “LAN” on page 30.
L
LAN LAN stands for Local Area Network (>= 10 Mbit/s). These networks are usually
limited to a small footprint (a building or even a floor). A LAN may often in-
clude a wide range very different computer systems.
LAN ports In the Network menu, you will see a list of all the network devices connected
via the LAN of the Gateway 400 with their respective names, if transmitted,
the assigned IP address and the MAC address of the device.
LED display LEDs (Light Emitting Diodes) serve as signal lamps that provide information
on the status of a device.
M
MAC Address The MAC (Media Access Control) address is the physical address of a network
component. The MAC address is unique world-wide and permanently as-
signed to the network component.
