Symbol Technologies LS 2106 manual Code Length, Continuous Code, Dead Zone, Decode Algorithm

	Glossary
Code Length	Number of data characters in a bar code between the start and stop
	characters, not including those characters.
Continuous Code	A bar code or symbol in which all spaces within the symbol are parts
	of characters. There are no intercharacter gaps in a continuous code.
	The absence of gaps allows for greater information density.
Dead Zone	An area within a scanner's field of view, in which specular reflection
	may prevent a successful decode.
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.
Depth of Field	The range between minimum and maximum distances at which a
	scanner can read a symbol with a certain minimum element width.
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.
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.
Element	Generic term for a bar or space.
Encoded Area	Total linear dimension occupied by all characters of a code pattern,
	including start/stop characters and data.
Host Computer	A computer that serves other terminals in a network, providing such
	services as computation, database access, supervisory programs, and
	network control.
IEC	International Electrotechnical Commission. This international agency
	regulates laser safety by specifying various laser operation classes
	based on power output during operation.
