autocode (s), autocodes (pl); automatic code (s), automatic codes (pl)
The process of using a computer to convert automatically a symbolic code into a machine code.
bar code
A standard method of identifying the manufacturer and product category of a particular item.
The barcode was adopted in the 1970's because the bars were easier for machines to read than optical characters.
The main drawbacks of barcodes are that they don't identify unique items and so scanners have to have "line of sight" to read them.
barcode printer, bar code printer, bar-code printer
A computer peripheral for printing barcode labels or tags which can be attached to physical objects.
Barcode printers are commonly used to label cartons before shipment or to label retail items with barcode symbology; that is, a specific type of barcode for tracking commercial items in stores.
bar-code scanner (s), bar-code scanner (pl); bar-code reader (s), bar-code readers (pl)
In computer science, an optical scanning device that reads texts which have been converted into a special bar code.
BASIC code
Beginners All-purpose Symbolic Instruction Code code.
binary code
A way of representing text or computer processor instructions by the use of the binary number system's two-binary digits 0 and 1.
A binary system in general is any system that allows just two choices; such as, a switch in an electronic system or a simple true or false test.
black code, Jim Crow Law
1. A code of law that defined and, especially, limited the rights of former slaves after the Civil War in the United States.
2. Statutes passed by pro-slavery, Southern states of the U.S.A. before and after the Civil War, which were meant to limit the civil rights of slaves or freed slaves.

electronic codebook mode, electronic code-book mode, ECB; block encryption
The use of a block cipher (encryption method), usually employing the data encryption standard (DES), in which each 64-bit block of data is enciphered or deciphered separately, and every bit in a given output block depends on every bit in its respective input block and on every bit in the key, but on no other bits.
electronic product code, EPC
A serial, created by the Auto-ID Center, that will complement barcodes.
The EPC has digits to identify the manufacturer, product category and the individual item.
