GLOSSARY
Access Point
A device that provides transparent access between Ethernet wired networks
and IEEE 802.11 interoperable radio-equipped mobile units. Hand-held mobile
computers, PDAs or other devices equipped with radio cards, communicate with
wired networks using Access Points (AP). The mobile unit (mobile computer)
may roam among the APs in the same subnet while maintaining a continuous,
seamless connection to the wired network.
Applet
Diminutive form of app (application), it refers to simple, single-function programs
that often ship with a larger product. Programs such as Windows' Calculator,
File Manager, and Notepad are examples of applets.
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.
Bluetooth®
A standard radio technology using a proprietary protocol. The onboard
Bluetooth® module in the mobile computer 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.
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.
Depth of Field (DOF)
The portion of a scene that appears acceptably sharp in the image. Although a
lens can precisely focus at only one distance, the decrease in sharpness is
