Different Types of Barcodes

A Barcode Symbology defines the technical details of a particular type of barcode: the width of the bars, character set, method of encoding, checksum specifications, etc. Most users are more interested in the general capabilities of a particular symbology (how much and what kind of data can it hold, what are its common uses, etc) than in the excruciating technical details.
