Glossary - 8 MC909X User Guide
L
laser scanner. A type of bar code reader that uses a beam of laser light.
LASER. (Light Amplification by Stimulated Emission of Radiation) The laser is an intense light source. Light
from a laser is all the same frequency, unlike the output of an incandescent bulb. Laser light is typically
coherent and has a high energy density.
Laser Diode. A gallium-arsenide semiconductor type of laser connected to a power source to generate a laser
beam. This laser type is a compact source of coherent light.
LCD. See Liquid Crystal Display.
LEAP. (Lightweight Extensible Authentication Protocol) A mutual authentication method that uses a username
and password system.
LED Indicator. A semiconductor diode (LED - Light Emitting Diode) used as an indicator, often in digital
displays. The semiconductor uses applied voltage to produce light of a certain frequency determined by the
semiconductor's particular chemical composition.
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
MC. Mobile computer.
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.
MIL. 1 mil = 1 thousandth of an inch.
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.
Misread (Misdecode). A condition which occurs when the data output of a reader or interface controller does
not agree with the data encoded within a bar code symbol.
Mobile Computer. In this text, mobile computer refers to the Symbol Series 9090 wireless portable computer.
It can be set up to run as a stand-alone device, or it can be set up to communicate with a network, using
wireless radio technology.
