Association. The process of determining the viability of the wireless connection and establishing a wireless network's root
and designated access points. A mobile computer associates with its wireless network as soon as it is powered on or
moves into range.
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.
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.
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
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.
CDRH Class 2. No additional software mechanisms are needed to conform to this limit. Laser operation in this class poses
no danger for unintentional direct human exposure.
CHAP. (Challenge Handshake Authentication Protocol) A type of authentication in which the authentication agent (typically
a network server) sends the client program a random value that is used only once and an ID value. Both the sender and
peer share a predefined secret. The peer concatenates the random value (or nonce), the ID and the secret and
calculates a one-way hash using MD5. The hash value is sent to the authenticator, which in turn builds that same string
on its side, calculates the MD5 sum itself and compares the result with the value received from the peer. If the values
match, the peer is authenticated.
Cold Boot. A cold boot restarts the MC9190-G and erases all user stored records and entries.
COM port. Communication port; ports are identified by number, e.g., COM1, COM2.
Cradle. A cradle is used for charging the terminal battery and for communicating with a host computer, and provides a
storage place for the terminal when not in use.
