GLOSSARY
Access Point
A device that provides transparent access between Ethernet wired networks and
IEEE 802.11 interoperable radio-equipped mobile units. Hand-held terminals, PDAs
or other devices equipped with radio cards, communicate with wired networks using
Access Points (AP). The mobile unit (PDA), 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 binary 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 PDA is compatible with the 1.2 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.
Decode
To recognize a bar code symbology (e.g., Codabar, Code 128, Code 3 of 9,
UPC/EAN, etc.) and analyze the content of the bar code scanned.
