Reply to comment by KrakenOfLakeZurich in ELI5: What is a network port? by Brianprokpo456

Thanks. This was the answer I understood the most. And honestly I didn't expect such a quick response. So thank you!

So in the end it is just a way to transmit information from one point to another by the same cable but without getting things awfully mixed.

Yes, and the ports exist at layer 4 of the transmission protocol. So it's not hardware related at all. They exist in the headers (just a few bits) of the packets that are being sent back and forth. So, to continue the example above, the ports are not a component of the apartments themselves, it's just written on the envelope of any mail or packages sent to and from those apartments.
