What are the different types of The World Wide Web?


  • Basic World Wide Web Model.
  • Universal Resource Identifies.
  • Hypertext Transfer Protocol.
  • Hypertext Markup Language.
  • Interactive World Wide Web Model.etc.


Which was the First World Wide Web Browser?

History of the World Wide Web



Tim Berners-Lee 



THE World Wide Web WAS INVENTED BY Tim Berners-Lee IN 1989.(Internet & world wide web)

Timothy John Berners-Lee(Tim Berners-Lee) was  known as an English Engineer and computer scientist. who contributed a lot to the invention of the Internet & World Wide Web?

www is an information system where documents and another web pages or Web sources are identified by Uniform Resource Locator( URLs) such as https://www.friend.com/), which may be interlinked by HTML and are accessible or scrolled over the Internet to find the information required by the users

The resources of the WWW are transferred via the Hypertext Transfer Protocol HTTP) and It may be accessed by users by a web browser or software application or any other medium .which is published on the Internet or uploaded in the Internet by any medium software application etc.is called a web server.

 Timothy John Berners-Lee(Tim Berners-Lee) wrote about the first web browser in 1990 while he was employed at CERN near Geneva, Switzerland. The browser was released outside CERN in 1991, first to other research institutions starting in January 1991 and then to the general public in August 1991.

The World Wide Web has been central to the development of the information age and is the primary tool billions of people use to interact on the Internet.

Paul Jones of UNC chapel hill in North Carolina announced in May 2013 that Tim Berners-Lee gave him what he says is the oldest known web page during a visit to UNC in 1991. Jones stored it on a Magneto-Optical drive and on his NeXT computer.

On 6 August 1991, Tim Berners-Lee published a short summary of the World Wide Web project on the newsgroup alt hypertext.
Historians generally agree that a turning point for the Web began with the 1993 introduction of  Mosaic.

Later Netscape A big competitor to Mosaic also gave his contribution to the world which was released a year later. the lesser-known Erwise and ViolaWWW. was also developed.which did not become very famous.

 Mosaic was developed at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana–Champaign beginning in late 1992.

The World Wide Web enabled the spread of information over the Internet through an easy-to-use and flexible format. It thus played an important role in popularising the use of the Internet.


CERN 



CERN computer scientist Tim Berners-Lee proposed an idea for a database of hypertext links that would allow people to send data and communicate across a network. Berners-Lee wasn't looking to transform modern life when he invented the World Wide Web; he had just got tired to change or switch computers whenever he needed to access information that wasn't on his main work computer.so as we say "Need is the Mother of all Inventions"
He needed a medium wherein there will be no need to change computers again & again an Invention of WWW was done.

Who created 1st search Engine for Internet browsing & When?
In 1992 Archie The first tool used for searching content on the Internet was Archie.
 It was named as Archie because it was named as Archive. And it stands for "archive" without the "v". It was basically created by Alan Emtage, Bill Heelan, and J. Peter Deutsch, They were computer science students at McGill University in Montreal, Quebec, Canada. 
In Archie manually the programs were downloaded, the directory listings of all the files located on public anonymous FTP (File Transfer Protocol) sites, creating a searchable database of file names; Archie Search The engine did not index the contents of these sites since the amount of data or the web pages were very limited it could be readily searched manually.
