Why not share knowledge is someone is asking earnestly?

Because there's literally nothing in it for me to help this guy unlock the stunning achievement of understanding why and in what manner computer systems communicate. This is intern level information, trivial to learn.

If you cannot post a message to help because "there is nothing in it for you"... please tell me what you got from posting this?

I really wanna know

You must be a joy to work with /s
