Interleaved 2 of 5 A binary bar code symbology representing character pairs
in groups of five bars and five interleaved spaces.
Interleaving provides for greater information density. The
location of wide elements (bar/spaces) within each group
determines which characters are encoded. This continuous
code type uses no intercharacter spaces. Only numeric (0 to
9) and START/STOP characters may be encoded.
Internet Protocol Address See IP.
IP Internet Protocol. The IP part of the TCP/IP communications
protocol. IP implements the network layer (layer 3) of the
protocol, which contains a network address and is used to
route a message to a different network or subnetwork. IP
accepts “packets” from the layer 4 transport protocol (TCP
or UDP), adds its own header to it and delivers a
“datagram” to the layer 2 data link protocol. It may also
break the packet into fragments to support the maximum
transmission unit (MTU) of the network.
IP Address (Internet Protocol address) The address of a computer
attached to an IP network. Every client and server station
must have a unique IP address. A 32-bit address used by a
computer on a IP network. Client workstations have 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.
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.
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.
