either a permanent address or one that is dynamically assigned to them each session. IP addresses are written as four
sets of numbers separated by periods; for example, 204.171.64.2.
L
LAN. Local area network. A radio network that supports data communication within a local area, such as within a warehouse
of building.
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.
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.
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.
Mobile Computer. In this text, mobile computer refers to the Motorola wireless handheld 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.
N
Nominal. The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and negative
deviations from this value.
Nominal Size. Standard size for a bar code symbol. Most UPC/EAN codes are used over a range of magnifications (e.g.,
from 0.80 to 2.00 of nominal).
