Bar Code

An arrangement of bars and spaces on a label, stamped, embossed onto an item or container that identifies the item and sometimes its quantity. A variety of fixed and variable length code schemes are used by industries and standards bodies to enable automatic interpretation by collection systems and avoid manual input. This is refered to as automatic recognition which enables input of alphabetic, numeric, marks and symbols, etc. digitally into the computer.

Binary

Denoting a numbering system to base 2 in which numbers are expressed as combinations of the digits 0 and 1, with positional weighting based on powers of 2. In computing these can be represented electrically by 'off' and 'on' respectively, or in machine-readable symbols by narrow and wide elements or by the absence or presence of a bar module.

Binary Level

A certian type of bar code. Bar widths consist of 2 types: a narrow bar and a wide bar.

(Also see Multi-level)

BWR
