I've wrote "absolute beginner", not "super noob". Absolute beginner is not a derogatory term. It is nothing wrong to be a beginner. You wrote your opening post as if that schematic was found somewhere else, so I've assumed you are following some shoddy blog instead of learning from better sources, so the advice to find another learning source.
And I've never say it's wrong to ask. Beginners are welcome, and anybody is encouraged to ask. I did not intend to make you feel bad. Also, I've never heard of a "net port", didn't know what you mean by that, thus the question.
This is a friendly place, please do not assume to malevolence what can be attributed to a misunderstanding.
