Answer 2

Deep web - the internet that can not be searched with a search engine. Such are cloud storage, illegal websites and everything you aren't supposed to see.

Dark web - illegal websites in the deep web.Such websites give illegal guns, illegal loans and often use crypto-currencies for purchasing and for anonymity. The dark web can be browsed to with Tor and the .onion extension.

Tor - the onion router. Made by the US army to make an anonymous, encrypted internet for use in the army. It bounces your network requests at volunteers' computers around the globe. Tor can access regular, http and https websites but can also access a .onion website that leads to the dark web.
