Flash memory is responsible for storing the system
firmware and is non-volatile. If the system power is
interrupted the data is not be lost.
An IP address for a network gateway or router. A mobile
computer may be part of a subnet as specified by its IP
address and Netmask. It can send packets directly to any
node on the same subnet. If the destination node is on a
different subnet, then the terminal sends the packet to the
gateway first. The gateway determines how to route the
packet to the destination subnet. This field is an option
used by networks that require gateways.
See Cold Boot.
A set of random frequencies designed to minimize
interference with other sets of random frequencies. A
hopping sequence determines the pattern with which a
station that uses frequency hopping changes its
communications frequency. See Frequency Hopping.
Hertz; A unit of frequency equal to one cycle per second.
A computer that serves other terminals in a network,
providing such services as computation, database access,
supervisory programs and network control.
Intelligent drive electronics. Refers to the solid-state hard
drive type.
International Electrotechnical Commission. This
international agency regulates laser safety by specifying
various laser operation classes based on power output
during operation.
This is the lowest power IEC laser classification.
Conformity is ensured through a software restriction of 120
seconds of laser operation within any 1000 second window
and an automatic laser shutdown if the scanner's
oscillating mirror fails.
See MAC Address.
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.
Input/Output Control.
Mobile computers with an integrated imager use digital
camera technology to take a digital picture of a bar code,
store the resulting image in memory and execute state-of-
the-art software decoding algorithms to extract the data
from the image.
The space between two adjacent bar code characters in a
discrete code.
