    • What is Web
      • Defination-It is a hypertext system that operates over the internet.It is a global information medium which users can read and write via computers connected to the Internet.
      • Difference between Internet And Web
      • Internet- Collection of interconnected computer networks.
      • World wide web-Infinitely larger collection of interconnected documents or content.
    • I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. — Tim Berners-Lee, 1999
    • History
      • 1980
      • -ENQUIRE by Tim Berners-Lee at CERN,which was the predecessor to the World Wide Web.It was a simple hypertext program.
      • -ENQUIRE had pages called cards and hyperlinks within the cards.
      • -There was a need that people were able to create cards independently of others and to link to other cards without updating the linked card.
      To be Continued.....
      • 1984
      • Berners-Lee considered its problems of information presentation: physicists from around the world needed to share data, and with no common machines and no common presentation software. He wrote a proposal in March 1989 for "a large hypertext database with typed links".
      • September 1990
      • Berners-Lee and Cailliau pitched their ideas to the European Conference on Hypertext Technology.
      To be Continued.....
      • Christmas 1990
      • Berners-Lee had built all the tools necessary for a working Web:
      • 1.HyperText Transfer Protocol (HTTP)
      • 2.HyperText Markup Language (HTML)
      • 3.First Web browser (named WorldWideWeb, which was also a Web editor)
      • 4.First HTTP server software (later known as CERN httpd)
      • 5.First web server
      • 6.First Web pages that described the project itself.
      • The browser could access Usenet newsgroups and FTP files as well
      To be Continued.....
      • August 6, 1991
      • -The debut of the Web
      • -Berners-Lee posted a short summary on the alt.hypertext newsgroup.
      • -Project aims to allow all links to be made to any information anywhere.
      • -To allow high energy physicists to share data, news, and documentation.
      • 1992-1995:Growth of www
      • -Graphical browser-Mosaic
      • -Microsoft windows browser-Cello
      • -May 1994- the first International WWW Conference
      • -September 1994- the World Wide Web Consortium (W3C)
      To be Continued.....
      • 1996-1998:Commercialization of www
      • -Public web presence
      • -Free publishing
      • -E-commerce
      • 1999-2001:'Dot Com' Boom
      • 2002-present
        -Google search engine -Social networking sites -Online departent stores -Advertising sites & auction sites
    • 1) Client makes webpage request using HTTP request msg. 2) It sends request from client to Web server Web server stores collection of web-pages created using markup language. Port 80 3) When requst arrives , server locates the requested page and send it to client using HTTP response msg. Function of Web Client (Browser) Web Server Client (Browser) Client (Browser) Internet
    • Basic Web Entities 1) HTML : Hypertext Markup Language It is used to create web page that is stored on web-server and provides information to client. 2) HTTP : Hypertext transfer protocol It is a protocol for transmitting web page over the internet. 3) URL : Uniform Resource Locator User types URL into browser(client) specifying the server hosting web page.
    • Web Standardiztion : Web standard is general term for formal standards and other technology specification that define and describe aspect of WWW World Wide Web Consortium – W3C is main international standard organization for www founded by Tim Berners-Lee in 1994. W3C standard : HTML, CSS, SOAP, XML, XSLT, Xquery, XHTML
    • HTML : Markup language for creating web page allows images and objects to be embedded and support intreactive forms Versions : 1) HTML 2.0 : Nov. 1995 by IETF HTML working group 2) HTML 3.2 : Jan 1997 W3C recommendation New features such as fonts tables, applet etc. 3) HTML 4.0 : Dec 1997 W3C recommendation Introduced CSS 4) HTML 4.1 : Dec 1999 W3C recommendation Just fixes bugs/error from HTML 4.0 5) XHTML 1.0: Jan 2000 W3C recommendation Reformulates HTML 4.01 into XML 6) HTML5: New generation for HTML Still in progress
    • Highlight of HTML5 Co-operation between W3C and WHATWG Modern browser support HTML5 New Elements: 1) Media element: <audio> :- sounds, audio streams (mp3, wav) <video> :- movie, video stream (mpeg4, webM) <embed>:- For embedded content such as plug in 2) Canvas Element: To make drawing on web page. Uses JavaScript to make drowing on Web page. 3) Input Element: tel,search,url,email,date
    • Web Generations
      • Web 1.0-Mostly read-only web
      • Web 2.0-Wildly read-write web
      • Web 3.0-Portable personal web
    • Web 1.0
      • Put content in web and push it to users
      • Static pages instead of dynamic user-generated content.
      • The use of framesets.
      • The use of tables to position and align elements on a page.
      • Online guestbooks.
      • GIF buttons, typically 88x31 pixels in size promoting web browsers and other products.
      • HTML forms sent via email.
      • Defects-
        1-Limited Content 2-Limited Creativity 3-Limited Business
    • Characteristics :
      • Rich user experience
      • User participation
      • Dynamic content
      • Metadata
      • Web standards
      • Scalability
      • Openness
      • Collective intelligence
    • Web 3.0
      • Next generation of web
      • Web 3.0 browser will act like personal assistant
      • Understood information over web
      • Instead of only keyword search ,it employs context based search
      • An approach to implement web 3.0 is semantic web
      • Ontologies
