Surface Web
The Surface Web (also called the Visible Web, Indexed Web, Indexable Web or Lightnet) is the portion of the World Wide Web that is readily available to the general public and searchable with standard web search engines. It is the opposite of the deep web, the part of the web not indexed by a web search engine. The Surface Web only consists of 10 percent of the information that is on the internet. The Surface Web is made with a collection of public web pages on a server accessible by any search engine. According to one source, , Google's Index of the Surface Web contains about 14.8 billion pages. See also * Clearnet (networking) Clearnet is a term that typically refers to the publicly accessible Internet. Sometimes "clearnet" is used as a synonym for " surface web"—excluding both the darknet and the deep web. The World Wide Web is one of the most popular distributed ...

World Wide Web
The World Wide Web (WWW or simply the Web) is an information system that enables Content (media), content sharing over the Internet through user-friendly ways meant to appeal to users beyond Information technology, IT specialists and hobbyists. It allows documents and other web resources to be accessed over the Internet according to specific rules of the HTTP, Hypertext Transfer Protocol (HTTP). The Web was invented by English computer scientist Tim Berners-Lee while at CERN in 1989 and opened to the public in 1993. It was conceived as a "universal linked information system". Documents and other media content are made available to the network through web servers and can be accessed by programs such as web browsers. Servers and resources on the World Wide Web are identified and located through character strings called uniform resource locators (URLs). The original and still very common document type is a web page formatted in Hypertext Markup Language (HTML). This markup lang ...

Web Search Engine
A search engine is a software system that provides hyperlinks to web pages, and other relevant information on World Wide Web, the Web in response to a user's web query, query. The user enters a query in a web browser or a mobile app, and the search engine results page, search results are typically presented as a list of hyperlinks accompanied by textual summaries and images. Users also have the option of limiting a search to specific types of results, such as images, videos, or news. For a search provider, its software engine, engine is part of a distributed computing system that can encompass many data centers throughout the world. The speed and accuracy of an engine's response to a query are based on a complex system of Search engine indexing, indexing that is continuously updated by automated web crawlers. This can include data mining the Computer file, files and databases stored on web servers, although some content is deep web, not accessible to crawlers. There have been ma ...

Deep Web
The deep web, invisible web, or hidden web are parts of the World Wide Web whose contents are not indexed by standard web search-engine programs. This is in contrast to the " surface web", which is accessible to anyone using the Internet. Computer scientist Michael K. Bergman is credited with inventing the term in 2001 as a search-indexing term. 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. 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. Terminology The first conflation of the terms "deep web" and " dark web" happened during 2009 when deep web search terminology was discussed together with illegal activities occurring on ...

Clearnet (networking)
Clearnet is a term that typically refers to the publicly accessible Internet. Sometimes "clearnet" is used as a synonym for " surface web"—excluding both the darknet and the deep web. The World Wide Web is one of the most popular distributed services on the Internet, and the surface web is composed of the web pages and databases that are indexed by traditional search engines. "Clearnet" can be seen as the opposite of the term " darknet", which typically describes the services built on Tor or other anonymity networks, the connection to which is encrypted and anonymized. Because the darknet is not publicly accessible, it is part of the deep web. The term "deep web", describes those parts of the Internet that are not indexed, whether or not they are publicly accessible. It includes web portals to databases that require text searches, and interactive web sites that require more user input than simply clicking hyperlinks. Characteristics Without the use of anonymity services like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Search Engines
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, internet telephony, streaming media and file sharing. The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication. The set of rules (communication protocols) to enable internetworking on the Internet arose from research and development commissioned ...
