Deep Web: All online content not indexed by standard search engines-private databases, paywalled articles, intranets, etc., comprising up to 90% of the internet's content.
Dark Web: A subset of the deep web accessible only via specialized software like the Tor Browser, known for anonymity and hidden .onion domains.
Tor Network: Software and infrastructure that enable anonymous communication by routing traffic through volunteer-operated relays and hidden services under .onion addresses.
