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.

D
DAQ
data acquisition–(1) collecting and measuring electrical signals from
sensors, transducers, and test probes or fixtures and inputting them to a
computer for processing; (2) collecting and measuring the same kinds
