what is the difference between pins and ports? cant find the answer any ware?

Hi Dannos,

Welcome to the forum.

Pins are the individual signal carriers and ports contain the group of individual pins.
For example, a computer with a parallel printer port may have one 25 way D type connector identified as an LPT port, this port in turn has 25 pins which can carry signals.

Hope this helps,
