Deepweb and Darknet

These two words are often spoken by the news media and we hear them on some TV shows, but they are never explained.

The Deepweb refers to part of the Internet, specifically the world wide web (anything that starts www) that isn't indexed by search engines, and can't be accessed by Google.

The Darknet refers to non-www networks, where users may need separate software to access them. For example, Silk Road and many illicit markets are hosted on Darknet networks like I2P and Tor.
