How the Internet Works

Do you ever wonder how the internet really works?

The Internet  is a global system of interconnected computer networks that serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email.

The origins of the Internet reach back to the 1960s. As of June 2012, more than 2.4 billion people—over a third of the world's human population—have used the services of the Internet.[1]
