It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, 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 and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing. - wikipedia - [WHAT IS THE INTERNET? or, "You Say Tomato, I Say TCP/IP"](http://www.20thingsilearned.com/en-US/what-is-the-internet/1) [read] - [How does the Internet work](http://www.w3.org/wiki/How_does_the_Internet_work) [read] - [How does the Internet Work?](http://web.stanford.edu/class/msande91si/www-spr04/readings/week1/InternetWhitepaper.htm) [read] - [How the Internet Works in 5 Minutes](https://www.youtube.com/watch?v=7_LPdttKXPc) [watch] - [How The Web Works](https://www.eventedmind.com/classes/how-the-web-works-7f40254c) [watch][$]
