The document summarizes how the internet works through a network hierarchy and protocols. It discusses how the internet is managed by nonprofit organizations and government agencies and paid for by taxpayers and businesses. It also outlines the layered network structure and protocols like TCP/IP that allow communication between connected devices and translation of domain names to IP addresses through DNS servers. Common internet applications and protocols for file transfer, web pages, email, and instant messaging are also summarized.

Editor's Notes

  1. This chapter takes you behind the scenes of the Internet. We look at how the Internet works and the various standards it follows. Along the way, we go behind the scenes of some Internet communication features, such as e-mail and instant messaging services, and discuss just how safe these features are and what you can do to make your communications even more secure.
