bus
The group of conductors that interconnect individual circuitry in a
computer. Typically, a bus is the expansion interface to which I/O or other
devices are connected. Examples of PC buses are the ISA bus and PCI bus.

channel
Pin or wire lead to which you apply or from which you read the analog or
digital signal. Analog signals can be single-ended or differential. For digital
signals, you group channels to form ports. Ports usually consist of either
four or eight digital channels.

CMRR
Common-Mode Rejection Ratio—A measure of the ability of a differential
amplifier to reject interference from a common-mode signal, usually
expressed in decibels (dB).

CODEC
coder-decoder—An electronic device that converts analog signals, such as
video and voice signals, into digital form, and then compresses them to
conserve bandwidth on a transmission path. The NI SPEEDY-33 CODEC
also converts digital signals into analog form.
