World Wide Web

What is the World Wide Web? • World Wide Web ("WWW" or simply the "Web") is a system of interlinked, hypertext documents that runs over the Internet.

How do we access the World Wide Web? • With a Web browser, a user views Web pages that may contain text, images, and other multimedia and navigates between them using hyperlinks.

Trivia! About the word “surfing” • The phrase "surfing the Internet" was first popularized in print by Jean Armour Polly, a librarian, in an article called Surfing the INTERNET, published in the University of Minnesota Wilson Library Bulletin in June, 1992.

Elaborating more on the World Wide Web • The World Wide Web ("WWW“) or simply the "Web“ is a global information medium which users can read and write via computers connected to the Internet. • is a wide-area hypermedia information retrieval initiative aiming to give universal access to a large universe of documents

When did it all began? • The origins of the World Wide Web can be traced back to 1980. Since then it has evolved far beyond what it’s creators imagined.

Take note! There is a difference • The term is often mistakenly used as a synonym for the Internet itself. • The Web is a service that operates over the Internet, as e-mail does. • The history of the Internet dates back significantly further than that of the World Wide Web.

What makes up World Wide Web? •

Hypertext #1

a format of information which allows, in a computer environment, one to move from one part of a document to another or from one document to another through internal connections among these documents (called " hyperlinks");

What is HyperText • Hypertext is text which is not constrained to be linear.Hypertext is text which contains links to other texts. The term was coined by Ted Nelson around 1965. • HyperMedia is a term used for hypertext which is not constrained to be text: it can include graphics, video and sound , for example. Apparently Ted Nelson was the first to use this term too. • Hypertext and HyperMedia are concepts, not products.

Dub… dub… dub… dub…. 1990 was a momentous year in world events. In February, Nelson Mandela was freed after 27 years in prison. In April, the space shuttle Discovery carried the Hubble Space Telescope into orbit. And in October, Germany was reunified. Then at the end of 1990, a revolution took place that changed the way we live today.

When and where did it all began? CERN, the European Organization for Nuclear Research, is where it all began in March 1989. A physicist, Tim Berners-Lee, wrote a proposal for information management showing how information could be transferred easily over the Internet by using hypertext, the now familiar point-and-click system of navigating through information.

History’s First! Hooray! http://info.cern.ch/ Was the website of the world's firstever web server

DO YOU KNOW THAT?!

History’s First! Hooray! The historic NeXT computer used by Tim Berners-Lee in 1990, on display in the Microcosm exhibition at CERN. It was the first web server, hypermedia browser and web editor.

What is Lee’s purpose in conceiving his idea? The idea was to connect hypertext with the Internet and personal computers, thereby having a single information network to help CERN physicists share all the computerstored information at the laboratory. Hypertext would enable users to browse easily between texts on web pages using links; The first examples were developed on NeXT computers.

Lee’s concept implemented of NeXT computers in CERN

How did the name came to be what it is? • Berners-Lee created a browser-editor with the goal of developing a tool to make the Web a creative space to share and edit information and build a common hypertext. What should they call this new browser: The Mine of Information? The Information Mesh? When they settled on a name in May 1990, it was the WorldWideWeb.
