system that finds web pages
that match a web search.
It searches the World Wide
Web in a systematic way for
particular information
specified in a textual web
search query.

and social bookmarking sites,
which are maintained by human
editors, search engines also
maintain real-time information
by running an algorithm on
a web crawler.
DARK WEB

cannot be indexed and
searched by a web search engine fall
under the category of deep web.

users) on the Internet was Archie.
It was created by Alan Emtage.
