How do highways carry multiple vehicle at one time?

There’s something called channels. That like having multiple lanes on a highway where you cannot change lanes.

There’s something called muxing (multiplexing). That’s like having a lane on the highway that’s being shared by different trucks, some from Walmart, some from Amazon. On highways, trucks are separated by distance, I.e 50 foot separation. On a wire, or a fiber, the packets are separated by a slight (time) gap.
