World Wide Web
History of the creation
Inventor of the World Wide Web are considered to Tim Berners-Lee and Robert Cailliau. Tim Berners-Lee is the author of technology HTTP, URI / URL and HTML. In 1980, he worked at the European Council for Nuclear Research software consultant. in Geneva, he wrote a program "Enkvayr", which used random association for data storage and laid the framework for the World Wide Web.
In 1989, while working at CERN, Tim Berners-Lee proposed a global hypertext project, now known as the World Wide Web. For the implementation of the project by Tim Berners-Lee invented identifiers URI, HTTP protocol and the language HTML. This technology, without which it is impossible to imagine the modern Internet. Between 1991 and 1993, Berners-Lee has improved technical specifications of these standards and published them. But still, officially the year of birth of the World Wide Web should be considered in 1989.
Protocol HTTP
this is the protocol, which is used by the service WWW (HiperText Transfer Protocol - the protocol ofthe transfer the hyper-text). Designation: working the hyper-references;the search for the documents;the transfer of documents to the client.
The project Berners-Lee wrote the world's first web server httpd and the world's first hypertext web browser, called WorldWideWeb. This browser was simultaneously with the WYSIWYG-editor, development was started in October 1990 and finished in December of the same year. The program runs on NeXTStep and began to spread over the Internet in the summer of 1991.
The world's first web site was placed Berners-Lee August 6, 1991 on the first Web server available at http://info.cern.ch/. Resource defines the concept of the World Wide Web, contains instructions for installing the Web server, use the browser, and so on. This site is also the world's first online directory, because later, Tim Berners-Lee posted and maintained there a list of links to other sites.
Web - page
this is each various document the having its own address.It can contain the most different the information:text;drawing;sound.
In the first photo in the World Wide Web was depicted Philco parody band Les Horribles Cernettes.
Since 1994, most of the work on the development of the World Wide Web took over the World Wide Web Consortium, founded and headed by Tim Berners-Lee. This consortium - the organization and develop and implement technology standards for the Internet and the World Wide Web.
W3C is developing for the Web common principles and standards, which are then implemented programs and equipment manufacturers. making the World Wide Web more perfect, versatile and comfortable. All recommendations World Wide Web Consortium are open, that is not protected by patents and can be implemented by anyone without any financial contributions to the consortium.
Information on the web may be displayed both passive and active - then the user can add information and edit it. To display the active processes in the World Wide Web include:guest books,forums,chats,blogs,wiki-projectssocial networksIt should be noted that this division is rather arbitrary.World Wide Web is sometimes ironically called Wild Wild Web - by analogy with the name of the eponymous film Wild Wild West.
Interesting fact
In 2011, in St. Petersburg planned to erect a monument to the World Wide Web. The composition should be a street bench abbreviated WWW with free access to the network.
