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.
CDMA. (Code Division Multiple Access) A digital cellular technology that uses spread spectrum techniques that
separates them through the use of digital frequency codes across the full available spectrum.
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.
Character. A pattern of bars and spaces which either directly represents data or indicates a control function,
such as a number, letter, punctuation mark, or communications control contained in a message.
Character Set. Those characters available for encoding in a particular bar code symbology.
Check Digit. A digit used to verify a correct symbol decode. The scanner inserts the decoded data into an
arithmetic formula and checks that the resulting number matches the encoded check digit. Check digits are
required for UPC but are optional for other symbologies. Using check digits decreases the chance of
substitution errors when a symbol is decoded.
Codabar. A discrete self-checking code with a character set consisting of digits 0 to 9 and six additional
characters: (-$:/,+).
Code 128. A high density symbology which allows the controller to encode all 128 ASCII characters without
adding extra symbol elements.
Code 3 of 9 (Code 39). A versatile and widely used alphanumeric bar code symbology with a set of 43
character types, including all uppercase letters, numerals from 0 to 9 and 7 special characters (space, minus
(-), plus (+), period (.), dollar sign ($), slash (/), and percent (%)). The code name is derived from the fact
that 3 of 9 elements representing a character are wide, while the remaining 6 are narrow.
