The Different Webs

#DarkWeb #DeepWeb #SurfaceWeb

In my attempt to better understand the surface, deep, and dark web, I've decided to create a post defining each in simple terms, along with other bits of information.

Surface Web vs. Deep Web vs. Dark Net vs. Dark Web

Surface web – The portion of the World Wide Web that is freely, directly accessible, and searchable with standard web search engines.

Deep web – All the parts of the World Wide Web that are not indexed/searchable by standard search engines. Webmail (Gmail, etc.), online banking accounts, contents behind a paywall, etc., are all a part of the deep web.

Darknet – An overlay network that can only be accessed via special software. (e.g. Tor, I2P, Freenet, DN42, etc.)

Dark web – Dark web refers to websites on a darknet. It is the World Wide Web of a darknet. Since the dark web is the collection of websites on a darknet, it also requires special software to access it.


Overlay – A computer network that is built on top of another network

Search engine indexing – The collection, parsing, and storing of data facilitates fast and accurate information retrieval.

Internet vs. World Wide Web

Internet – “The internet is the physical network of network of networks, and so on.”

World Wide Web – “The World Wide Web, or simply web, is a way of accessing information over the medium of the internet.”
