Glossary - 2 WT4070/90 Wearable Terminal Integrator Guide
ANSI Terminal. A display terminal that follows commands in the ANSI standard terminal language. For example, it uses
escape sequences to control the cursor, clear the screen and set colors. Communications programs support the ANSI
terminal mode and often default to this terminal emulation for dial-up connections to online services.
Association. The process of determining the viability of the wireless connection and establishing a wireless network's root
and designated access points. A wearable terminal associates with its wireless network as soon as it is powered on or
moves into range.
Autodiscrimination. The ability of an interface controller to determine the code type of a scanned bar code. After this
determination is made, the information content is decoded.
B
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. See Symbology.
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). Bits transmitted or received.
Bluetooth. A low-cost, short-range radio link between two devices. Bluetooth can replace cables and can be used to create
ad hoc networks and provide a standard way to connect devices.
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.
bps. See Bits 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 is used to store one ASCII character.
boot or boot-up. The process a computer goes through when it starts. During boot-up, the computer can run self-diagnostic
tests and configure hardware and software.
C
CAM. (Continuously Aware Mode) Mode in which the adapter is instructed to continually check for network activity.
CDRH. (Center for Devices and Radiological Health) A federal agency responsible for regulating laser product safety. This
agency specifies various laser operation classes based on power output during operation.
CDRH Class 1. This is the lowest power CDRH laser classification. This class is considered intrinsically safe, even if all laser
output were directed into the eye's pupil. There are no special operating procedures for this class.
