Deep web
The deep web,[1] invisible web,[2] or hidden web[3] are parts of the World Wide Web whose contents are not indexed by standard web search-engine programs.[4] This is in contrast to the "surface web", which is accessible to anyone using the Internet.[5] Computer scientist Michael K. Bergman is credited with inventing the term in 2001 as a search-indexing term.[6]
Deep web sites can be accessed by a direct URL or IP address, but may require entering a password or other security information to access actual content.[7][8] Uses of deep web sites include web mail, online banking, cloud storage, restricted-access social-media pages and profiles, and web forums that require registration for viewing content. It also includes paywalled services such as video on demand and some online magazines and newspapers.
