MFLOPS million floating-point operations per second—the unit for expressing the
computational power of a processor
MIPS million instructions per second—the unit for expressing the speed of
processor machine code instructions
MISO Master-In-Slave-Out signal
MITE MXI Interfaces to Everything—a custom ASIC designed by National
Instruments that implements the PCI bus interface. The MITE supports bus
mastering for high speed data transfers over the PCI bus
MOSI Master-Out-Slave-In signal
MS million samples
MSB mostsignificantbit
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

NI-SCOPE 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
nonreferenced signal
sources
signal sources with voltage signals that are not connected to an absolute
reference or system ground. Also called floating signal sources. Some
common example of nonreferenced signal sources are batteries,
transformers, or thermocouples
