It's actually much simpler than that. When you transmit you also listen. If what you hear is not what you sent, there is a collision, and you backoff.

- jhayward 2y agoTo be specific, it's even more basic than that. For 10Base-5 and all the coax ethernets, it was "if there's more energy on the wire than you are transmitting, a collision is present".
