bandwidth can be divided into 15 different channels.
CMOS (Complementary Metal-Oxide Semiconductor)
A type of integrated circuit noted for its extremely low power consumption.
controller
An electronic device that interfaces between the data collection devices and the
system computer.
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance)
CSMA is a protocol in which each node senses whether or not a channel is in
use before attempting to transmit information. CA is an algorithm by which
channel time is reserved to avoid collisions.
data collection device
A device used with a scanner to collect data from scanned bar codes and send
it to a host computer.
