LAN – Local Area Network
A system in which computer users are connected
within a company or an organisation and are often
also connected to central data collections stored on
LAN servers.
MAC Address
The MAC address (media access control address) is the
hardware address of every individual network adapter.
It serves as a unique identifier for the device in a com-
puter network.
Passphrase Key
The network key that is used for authentication on a
WEP/ WPA2 encrypted network.
SSID
By providing different network call signs, it is possible
to operate various wireless LANs at the same location.
The SSID is set at the base station. To connect several
base stations to the same network, they need to be set
to the same SSID; this is then known as an ESSID (ex-
tended SSID).
Subnet mask
A subnet is a subordinate part of a network. It collates
several consecutive IP addresses by means of a sub-
net mask.
