The internet is the global highway that allows digital information to travel. And the “roads” of the internet digital highway are made up of an international computer network superstructure that enables businesses, people, and governments to access it.
The internet can also be delivered via different types of technologies, which is why you get internet service providers (ISPs) with DSL internet service, cable internet service, satellite internet service, and fiber internet service. They all connect you to that major network of the internet by first connecting you to your internet provider's network, but depending on the different technology backing your internet service, you might experience slower or faster speeds.
But describing the internet simply as “an international computer network” or just a “service” doesn’t give enough credit to the massive change that it represents. It’s like describing The Beatles as “four musicians from England.” The internet may be just a giant network formed by international computer links, but it’s also one of humanity’s most important technological achievements. The internet delivers instant communication, connection, and access to information all over the planet, and makes it faster and easier for people to do business, make friends, and share ideas.
