Let me be a little more explicit about that, with an example. A computer can mostly work but have a failing serial port. Then the component to look at is the serial port, not the whole computer. The serial port will usually work or not work.

The other part of this is serial & parallel ports aren't often used these days, having been supplanted by USB.  Why bother testing something that's not likely to be used?
