title: Concept of channel, port and line in labview programming
body: <p>I am starting to learn the labview programming from the code written by someone else long time ago. Here I saw IO channel, line and port, I guess their meaning by reading code but I am looking someone to clarify that for me. To my understanding, IO channel is refer to analogy input/output port, port refer to 8-bit, 16-bit or 32-bit digital input/output pins, each bit (pin) is called a line. Is that correct?</p>
