Glossary

Aperture	The opening in an optical system defined by a lens or baffle that
	establishes the field of view.
ASCII	American Standard Code for Information Interchange. A 7 bit-plus-
	parity code representing 128 letters, numerals, punctuation marks,
	and control characters. It is a standard data transmission code in the
	U.S.
Autodiscrimination	The ability of an interface controller to determine the code type of a
	scanned bar code. After this determination is made, the information
	content can be decoded.
Bar	The dark element in a printed bar code symbol.
Bar Code Density	The number of characters represented per unit of measurement
	(e.g., characters per inch).
Bar Height	The dimension of a bar measured perpendicular to the bar width.
Bar Width	Thickness of a bar measured from the edge closest to the symbol start
	character to the trailing edge of the same bar.
Baud Rate	A measure of the data flow or number of signaling events occurring
	per second. When one bit is the standard "event," this is a measure of
	bits per second (bps). For example, a baud rate of 50 means
	transmission of 50 bits of data per second.
Bit	Binary digit. One bit is the basic unit of binary information. Generally,
	eight consecutive bits compose one byte of data. The pattern of 0 and
	1 values within the byte determines its meaning.
