Mbytes/s a unit for data transfer that means 1 million or 106 bytes/s
MIPS million instructions per second—the unit for expressing the speed of
processor machine code instructions
MS million samples
MSB most significant bit
MTBF mean time between failure
mux multiplexer—a switching device with multiple inputs that sequentially
connects each of its inputs to its output, typically at high speeds, in
order to measure several signals with a single analog input channel
NNI-DAQ NI driver software for DAQ hardware

noise an undesirable electrical signal—Noise comes from external sources
such as the AC power line, motors, generators, transformers,
fluorescent lights, soldering irons, CRT displays, computers, electrical
storms, welders, radio transmitters, and internal sources such as
semiconductors, resistors, and capacitors. Noise corrupts signals you
are trying to send or receive.
Oonboard RAM optional RAM usually installed into SIMM slots
operating system base-level software that controls a computer, runs programs, interacts
with users, and communicates with installed hardware or peripheral
devices
output enable relay a relay switch at the output of the DAQArb 5411 that can enable the
waveform generation at any time or that can connect the output to
ground
