tional trade association representing automatic identification and mobility tech-
nology solution providers.
AIM DPM Quality Guideline
Standard applicable to the symbol quality assessment of direct part marking
(DPM) performed in using two-dimensional bar code symbols. It defines modifi
-
cations to the measurement and grading of several symbol quality parameters.
Barcodes (1D Codes)
A pattern of variable-width bars and spaces which represents numeric or alpha-
numeric data in machine-readable form. The general format of a barcode sym-
bol consists of a leading margin, start character, data or message character,
check character (if any), stop character, and trailing margin. Within this frame
-
work, each recognizable symbology uses its own unique format.
BIOS
Basic Input Output System. A collection of ROM-based code with a standard API
used to interface with standard PC hardware.
Bit
Binary digit. One bit is the basic unit of binary information. Generally, eight con-
secutive bits compose one byte of data. The pattern of 0 and 1 values within the
byte determines its meaning.
Bits per Second (bps)
Number of bits transmitted or received per second.
Bright Field Illumination
Lighting of surfaces at high (narrow) angles used to provide maximum reflection
of the light to the reader’s lens. This is effective on surfaces that absorb light or
are not highly reflective and also on low contrast codes.
Byte
On an addressable boundary, eight adjacent binary digits (0 and 1) combined in
a pattern to represent a specific character or numeric value. Bits are numbered
from the right, 0 through 7, with bit 0 the low-order bit. One byte in memory can
be used to store one ASCII character.
