Another technique is having s single wire do multiple purposes.
Did you know, you can send audio, aka speaker output over the 120 VAC wires in your home?
Before wireless speakers, this was a thing. Every outlet in your pre-wired home can double as a speaker connection - with proper speakers of course. You can unplug the speaker and plug in a vacuum.
Sending data and power in the same wire is common too.
