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.

Discrete Code
A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the 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.

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.

H

Host Computer
A computer that serves other terminals in a network, providing such
services as computation, database access, supervisory programs, and
network control.
