  Barcoding Inc. - Barcode Symbology Definitions   (Site not responding. Last check: 2007-10-21)
Barcodes look "strange" because the bars and spaces are the elements of a language which can be easily understood by a computer.
In essence, barcode symbologies are a sort of "in-between" language which allows humans and computers to communicate.
The specification of a symbology includes the encoding of the single digits/characters of the message as well as the start and stop markers into bars and space, the size of the quiet zone required to be before and after the barcode as well as the computation of a checksum.

 GENERAL SYMBOLOGY BACKGROUND INFORMATION
Symbologies are systems of encoding data such that a scanner and/or a decoding system may together read and decode the data encoded in the barcode.
A discrete symbology is one where each and every character encoded in the symbol may be interpeted individually without respect to the rest of the barcode.
Continuous symbologies normally implement some kind of special termation bar or termination sequence such that the last space of the last data character is terminated by the termination bar.

 Barcode Symbology Choice Evaluation
The type of barcode to use for a particular situation depends upon: (1) the implementation; (2) the data-to-encode in the barcode and (3) how the barcode will be printed.
Each type of symbology (or barcode type) is a standard that defines the printed symbol and how a device such as a barcode scanner reads and decodes the printed symbol.
Before selecting a symbology to use, check to determine if there is an established standard for the industry by contacting the respective industry standard board for the correct symbology choice.

In barcodes, every character has a distinct representation in a combination of wide and narrow bars and wide and narrow spaces and the barcode scanner is able to translate this back into the characters that these bars and spaces represent.
Several of the barcode symbologies are considered to be "self-checking." This means that the barcode has a particular format that helps the barcode reader determine that it has read the entire barcode.

 AIM - Barcode technology
Coupled with the improvements in data accuracy that accompanies the adoption of bar code technology over keyboard data entry, bar code systems are critical elements in conducting business in today’s global economy.
Bar code technology encompasses the symbologies that encode data to be optically read, the printing technologies that produce machine-readable symbols, the scanners and decoders that capture visual images of the symbologies and convert them to computer-compatible digital data, and the verifiers that validate symbol quality.
The various bar code symbologies differ both in the way they represent data and in the type of data they can encode: some only encode numbers; others encode numbers, letters, and a few punctuation characters; still others offer encodation of the 128-character, and even 256-character, ASCII sets.
