encryption
E
encryption: The device allows use of
data encryption compliant with the
IEEE802.11 standard WEP (Wired
Equivalent Privacy) and 128 bit WEP.
Data encryption protects your data from
external access.
ESSID: See network name.
G
global IP address: A global IP address
is used to identify a computer directly
connected to the Internet. It is assigned
by a public organization such as the
Network Information Center.
H
hidden station problem: Hidden sta-
tions are terminals (for example, comput-
ers with a wireless LAN card installed)
that can communicate with a common
access point, but are in a position where
the signals from one cannot reach the
other. If hidden terminals try to contact
the access point at the same time, their
trans-missions cannot be properly
received and retries will result, thereby
degrading LAN operation.
I
IEEE 802.1x: A standard for verifying
users on a LAN. Transmissions from
unverified users are blocked. Only
verified users are allowed to transmit on
the LAN.
Glossary-2
IEEE 802.11b (IEEE 802.11): A wireless
LAN standard that enables data trans-
mission at a speed of 11 Mbps and a
wave length of 2.4GHz. Devices can be
located up to 100 meters from the access
point.
infrastructure mode: When the LAN
transmissions are made through an
access point.
IP address: Internet Protocol Address
is a unique 32-bit addresses assigned to
each node on networks that use IP.
ISP: Internet Service Provider is a com-
pany that provides server computers for
connection to the Internet.
L
local IP address: A local Internet Proto-
col Address is a unique 32-bit addresses
assigned to each node on a LAN using
the TCP/IP standard.
LAN: A Local Area Network is a com-
puter network limited to the immediate
area, usually the same building or floor
of a building.
M
MAC address: The Media Access
Control address is your computer's
unique hardware number that identifies
it on a LAN.
MAC address filtering: Ensures that
only computers that are registered with
the device will be allowed access, either
to the Internet or to a wired LAN.
