It’s one way, ouf of many, to use the Internet. Indeed, the most widespread and successful way — the way that came to define most people’s understanding of the Internet. It’s a model of software that says pages that connect to one another via links. That linking is called hypertext transfer protocol (aka what that “http” in your URLs stands for). Every webpage and website is on the World Wide Web. Think of it this way: if the Internet is the ocean, then the World Wide Web is a massive fleet of ships and submarines, taking people through that ocean.
