My house gets internet via a magical coax cable that is, I assume, connected to the rest of the world via my Internet Service Provider. This cable connects directly into my router, which links to all the devices in my home.

My question is: Where does this magic cable go?

Some followup questions: How long is the cable?

How does so much data go through a single-pin coax cable? Wouldn't it be better if there were more pins, like in a twinax configuration?

There are also other houses in my neighborhood. Are their cables connected to mine? Can their routers see the packets sent by my router, similar to ethernet?

How has your day been?
