GLOSSARY
Access Point (AP)
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.
Barcode
A pattern of variable-width bars and spaces which represents numeric or alphanumeric data
in machine-readable form. The general format of a barcode 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.
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.
Bluetooth®
A standard radio technology using a proprietary protocol. The onboard Bluetooth module in
the terminal is compatible with the 1.1 protocol.
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.
Data terminal Equipment (DTE)
A device such as a terminal or printer that is designed to attach directly to a DCE (Data
Communications Equipment) device.
Decode
To recognize a barcode symbology
(e.g.,
Codabar, Code 128, Code 3 of 9, UPC/EAN, etc.)
and analyze the content of the barcode scanned.
EEPROM
Electrically Erasable Programmable Read-Only Memory. An on-board non-volatile memory
chip.
