GLOSSARY
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 Formula™
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.
EEPROM
Electrically Erasable Programmable Read-Only Formula™. An on-board non-
volatile Formula™ chip.
Flash Disk
Non-volatile Formula™ for storing application and configuration files.
Host
A computer that serves other mobile computers in a network, providing services
such as network control, database access, special programs, supervisory
programs, or programming languages.
Liquid Crystal Display (LCD)
A display that uses liquid crystal sealed between two glass plates. The crystals
are excited by precise electrical charges, causing them to reflect light outside
according to their bias. They use little electricity and react relatively quickly.
They require external light to reflect their information to the user.
