D. a broadband Internet connection

Answer 1

The Internet Backbone refers to the main pathway of high-speed communications lines through which all internet traffic flows.

Step-by-step explanation:

The Internet Backbone refers to the main pathway of high-speed communications lines through which all internet traffic flows. It is the network of high-capacity fiber optic cables and routers that connect the different networks and data centers around the world.

Imagine the Internet as a global highway and the Internet Backbone as the main road that all the traffic travels on. Just like how all the cars on the road need to use the main road to reach their destinations, all the data packets on the Internet need to use the Internet Backbone to reach their intended destinations.

For example, when you click on a website link or send an email, the data travels through multiple routers and connects to the Internet Backbone at some point, which ensures that the data can find its way to its destination efficiently.
