Decode. To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the content of the specific bar code
scanned.
Decode Algorithm. A decoding scheme that converts pulse widths into data representation of the letters or numbers
encoded within a bar code symbol.
Depth of Field. The range between minimum and maximum distances at which a scanner can read a symbol with a certain
minimum element width.
Device Configuration Package. The Device Configuration Package provides the flash partitions, Terminal Configuration
Manager (TCM) and the associated TCM scripts. With this package hex images that represent flash partitions can be
created and downloaded to the mobile computer.
Discrete 2 of 5. A binary bar code symbology representing each character by a group of five bars, two of which are wide.
The location of wide bars in the group determines which character is encoded; spaces are insignificant. Only numeric
characters (0 to 9) and START/STOP characters may be encoded.
E
EAN. European Article Number. This European/International version of the UPC provides its own coding format and
symbology standards. Element dimensions are specified metrically. EAN is used primarily in retail.
EMDK. Enterprise Mobility Developer's Kit.
ESD. Electro-Static Discharge
F
FHSS (Frequency Hopping Spread Spectrum). A method of transmitting radio signals by rapidly switching a carrier among
many frequency channels, using a pseudorandom sequence known to both transmitter and receiver.
File Transfer Protocol (FTP). A TCP/IP application protocol governing file transfer via network or telephone lines. See
TCP/IP.
Flash Memory. Flash memory is nonvolatile, semi-permanent storage that can be electronically erased in the circuit and
reprogrammed.
H
Hard Reset. See Cold Boot.
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.
