How computers know which cable to use to send internet signal?

Question

I’m sort of aware of DNS, IP, ARP – all the high level internet stuff.

But if computers look for each other, how do they choose which cable should they send info through? How DNS server chooses “the road” to another computer? Or is it pushing signals everywhere it can and other computers ignore what’s not for them?

>How DNS server chooses “the road” to another computer?

* It doesn’t.
* DNS just translates domain names like [www.google.com](https://www.google.com) to IP addresses like 172.217.11.36
* It gives that back to your browser and basically says “good luck!”
