Answer 1

It’s a service that connects the signal from one computer to another through a complex network of severs, cables, and some wireless signals. It’s a service, so they can charge for it. You could build your own WiFi network if you wanted, but it would be prohibitively expensive if you’re not a major corporation.

But it’s not something you can hold exactly.
