Deep web and dark web are two terms that some people use almost interchangeably. In actuality, they have many differences between them, and they are used for extremely different purposes.
It’s extremely common and makes up over 90% of the internet. The surface web is any website that is publicly available and readily indexed by search engines.
Originally created as a way for government agents and their contacts to communicate with one another, the dark web has morphed into a decentralized network of sites that are unreachable by all search engines and most browsers.
