G–3
D
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.
