Hard Reset See Cold Boot.
Hopping Sequence 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.
Hz Hertz; A unit of frequency equal to one cycle per second.
Host Computer A computer that serves other terminals in a network,
providing such services as computation, database access,
supervisory programs and network control.
IDE Intelligent drive electronics. Refers to the solid-state hard
drive type.
IEC International Electrotechnical Commission. This
international agency regulates laser safety by specifying
various laser operation classes based on power output
during operation.
IEC (825) Class 1 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.
IEEE Address See MAC Address.
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.
IOCTL Input/Output Control.
IP Internet Protocol.
imaging scanning 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.
