Liquid Crystal Display (LCD).
A display that uses liquid crystal sealed between two glass plates. The crystals are
excited by precise electrical charges, causing them to reflect light outside according to their bias. They use little
electricity and react relatively quickly. They require external light to reflect their information to the user.
Light Emitting Diode.
See LED.
M
MDN.
Mobile Directory Number. The directory listing telephone number that is dialed (generally using POTS) to reach
a mobile unit. The MDN is usually associated with a MIN in a cellular telephone -- in the US and Canada, the MDN
and MIN are the same value for voice cellular users. International roaming considerations often result in the MDN
being different from the MIN.
MIN.
Mobile Identification Number. The unique account number associated with a cellular device. It is broadcast by the
cellular device when accessing the cellular system.
N
NVM.
Non-Volatile Memory.
O
ODI.
See Open Data-Link Interface.
Open Data-Link Interface (ODI).
Novell’s driver specification for an interface between network hardware and
higher-level protocols. It supports multiple protocols on a single NIC (Network Interface Controller). It is capable of
understanding and translating any network information or request sent by any other ODI-compatible protocol into
something a NetWare client can understand and process.
Open System Authentication.
Open System authentication is a null authentication algorithm.
P
PAN .
Personal area network. Using Bluetooth wireless technology, PANs enable devices to communicate wirelessly.
Generally, a wireless PAN consists of a dynamic group of less than 255 devices that communicate within about a
33-foot range. Only devices within this limited area typically participate in the network.
Parameter.
A variable that can have different values assigned to it.
PING.
(Packet Internet Groper) An Internet utility used to determine whether a particular IP address is online. It is used
to test and debug a network by sending out a packet and waiting for a response.
