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 se ...

World Wide Web
The World Wide Web (WWW), commonly known as the Web, is an information system enabling documents and other web resources to be accessed over the Internet. Documents and downloadable media 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 language supports plain text, images, embedded video and audio contents, and scripts (short programs) that implement complex user interaction. The HTML language also supports hyperlinks (embedded URLs) which provide immediate access to other web resources. Web navigation, or web surfing, is the common practice of following such hyperlinks across multiple websites. Web applications are web pages that function as application s ...

Web Search Engine
A search engine is a software system designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). When a user enters a query into a search engine, the engine scans its index of web pages to find those that are relevant to the user's query. The results are then ranked by relevancy and displayed to the user. The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories 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. Any internet-based content that can't be indexed and searched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Such sites have uses such as web mail, online banking, cloud storage, restricted-access social-media pages and profiles, some web forums and code language 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" with "dark web" happened during 2009 when deep web search terminology was discussed together with illegal activities occurr ...

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 deep web, which is not indexed, is still 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 Tor, browsing the clearnet is typically not anonymous; most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Internet Terminology
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 inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource sharing. The ...
