The Deep Web refers to parts of the internet that are not indexed by traditional search engines like Google or Bing. This includes databases, private corporate sites, medical records, and academic resources. Unlike the surface web, which is easily accessible, the Deep Web requires specific permissions or credentials to access its content. While often confused with the Dark Web, the Deep Web is much larger and primarily consists of legitimate and legal information. It serves various purposes, such as protecting sensitive data and providing access to specialized resources that are not meant for public viewing.
