(Invisible Web) galley (term used to describe all the information available on the World Wide Web that cannot be found by using general-purpose search engines; phrase coined by Dr. Jill Ellsworth in 1994; in 2003, the School of Information Management and Systems at the University of California, Berkeley, published a document titled "How Much Information 2003" in which the size of the 2002 Internet, given in terabytes, included the "Surface Web" (167 terabytes), the "Deep Web" (91,850), "E-mail (originals)" (440,606) and "Instant messaging" (274)) Wikipedia, Dec. 11, 2008 (deep Web; also called Deepnet, the invisible Web, or the hidden Web; also called Deepnet, the invisible Web, or the hidden Web; refers to World Wide Web content that is not part of the surface Web, which is indexed by search engines; estimated that the deep Web is several orders of magnitude larger than the surface Web) The Invisible Web, what it is, how you can find it, Nov. 10, 2018, via Lifewire WWW site, Dec. 17, 2018: (The term "invisible web" mainly refers to the vast repository of information that search engines and directories don't have direct access to, like databases. Unlike pages on the visible Web (that is, the Web that you can access from search engines and directories), information in databases is generally inaccessible to the software spiders and crawlers that create search engine indexes. Users are able to access most of this information, but only through specific searches that unlock where this information lives.) |
