Glossary - 6 MC7090CN User Guide
IS-95. Interim Standard 95. The EIA/TIA standard that governs the operation of CDMA cellular service. Versions
include IS-95A and IS-95B. See CDMA.
K
Key. A key is the specific code used by the algorithm to encrypt or decrypt the data. Also see, Encryption and
Decrypting.
L
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.
laser scanner. A type of bar code reader that uses a beam of laser light.
LCD. See Liquid Crystal Display.
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.
Light Emitting Diode. See LED.
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.
M
MC. Mobile Computer.
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.
