Glossary
Code Length
Number of data characters in a bar code between the start and stop
characters, not including those characters.
Continuous Code
A bar code or symbol in which all spaces within the symbol are parts of
characters. There are no intercharacter gaps in a continuous code. The
absence of gaps allows for greater information density.
CTS
Clear to send.
Dead Zone
An area within a scanner’s field of view, in which specular reflection may
prevent a successful decode.
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.
Digitized Bar
Pattern (DBP)
A digital representation of a decoded bar code.
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.
Discrete Code
A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the code.
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.
Element
Generic term for a bar or space.
Encoded Area
Total linear dimension occupied by all characters of a code pattern, including
start/stop characters and data.
Host Computer
A computer that serves other terminals in a network, providing such services
as computation, database access, supervisory programs, and network
control.
IEC
International Electrotechnical Commission. This international agency
regulates laser safety by specifying various laser operation classes based on
power output during operation.
