Answer 1

Bandwidth is a finite resource. Advertised Internet speeds are like plane tickets, they are oversold. It’s the only way to keep costs down and advertise good speeds, it relies on everyone not using their connection to the max all the time.

That’s why busines/industrial dedicated Bandwidth is so expensive. You can pay hundreds per Mbps in that scenario. That’s because the ISP has to actually reserve that Bandwidth whether you are using it or not.
