GLOSSARY

Access Point
A device that provides transparent access between Ethernet wired networks and
IEEE 802.11 interoperable radio-equipped mobile units (MUs). Datalogic hand-held
computers, or other devices equipped with a PCMCIA slot, communicate with wired
networks using Access Points (AP). The mobile unit may roam among the APs in the
same subnet while maintaining a continuous, seamless connection to the wired
network.
Bar Code
A pattern of variable-width bars and spaces which represents numeric or
alphanumeric data in machine-readable form. The general format of a bar code
symbol consists of a leading margin, start character, data or message character,
check character (if any), stop character, and trailing margin. Within this framework,
each recognizable symbology uses its own unique format.
Baud Rate
A measure for data transmission speed.
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
consecutive 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.
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.
Data Communications Equipment (DCE)
A device such as a modem that is designed to attach directly to a DTE (Data
Terminal Equipment) device.
