Innovation of web

  1. 1. INNOVATION OF WEB
  2. 2. Agenda What is Web? History Function of Web Basic Web entities Web Standardization Web Generations References
  3. 3. What is Web <ul><li>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.
  4. 4. Difference between Internet And Web </li></ul><ul><li>Internet- Collection of interconnected computer networks.
  5. 5. World wide web-Infinitely larger collection of interconnected documents or content. </li></ul>
  6. 6. 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
  7. 7. History <ul><li>1980
  8. 8. -ENQUIRE by Tim Berners-Lee at CERN,which was the predecessor to the World Wide Web.It was a simple hypertext program.
  9. 9. -ENQUIRE had pages called cards and hyperlinks within the cards.
  10. 10. -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. </li></ul>To be Continued.....
  11. 11. <ul><li>1984
  12. 12. 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 &quot;a large hypertext database with typed links&quot;.
  13. 13. September 1990
  14. 14. Berners-Lee and Cailliau pitched their ideas to the European Conference on Hypertext Technology. </li></ul>To be Continued.....
  15. 15. <ul><li>Christmas 1990
  16. 16. Berners-Lee had built all the tools necessary for a working Web:
  17. 17. 1.HyperText Transfer Protocol (HTTP)
  18. 18. 2.HyperText Markup Language (HTML)
  19. 19. 3.First Web browser (named WorldWideWeb, which was also a Web editor)
  20. 20. 4.First HTTP server software (later known as CERN httpd)
  21. 21. 5.First web server
  22. 22. 6.First Web pages that described the project itself.
  23. 23. The browser could access Usenet newsgroups and FTP files as well </li></ul>To be Continued.....
  24. 24. <ul><li>August 6, 1991
  25. 25. -The debut of the Web
  26. 26. -Berners-Lee posted a short summary on the alt.hypertext newsgroup.
  27. 27. -Project aims to allow all links to be made to any information anywhere.
  28. 28. -To allow high energy physicists to share data, news, and documentation.
  29. 29. 1992-1995:Growth of www
  30. 30. -Graphical browser-Mosaic
  31. 31. -Microsoft windows browser-Cello
  32. 32. -May 1994- the first International WWW Conference
  33. 33. -September 1994- the World Wide Web Consortium (W3C) </li></ul>To be Continued.....
  34. 34. <ul><li>1996-1998:Commercialization of www
  35. 35. -Public web presence
  36. 36. -Free publishing
  37. 37. -E-commerce
  38. 38. 1999-2001:'Dot Com' Boom
  39. 39. 2002-present </li></ul><ul>-Google search engine -Social networking sites -Online departent stores -Advertising sites & auction sites </ul>
  40. 40. 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
  41. 41. 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.
  42. 42. 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
  43. 43. 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
  44. 44. 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
  45. 45. Web Generations <ul><li>Web 1.0-Mostly read-only web
  46. 46. Web 2.0-Wildly read-write web
  47. 47. Web 3.0-Portable personal web </li></ul>
  48. 48. Web 1.0 <ul><li>Put content in web and push it to users </li></ul><ul><li>Static pages instead of dynamic user-generated content.
  49. 49. The use of framesets.
  50. 50. The use of tables to position and align elements on a page.
  51. 51. Online guestbooks.
  52. 52. GIF buttons, typically 88x31 pixels in size promoting web browsers and other products.
  53. 53. HTML forms sent via email.
  54. 54. Defects- </li></ul><ul>1-Limited Content 2-Limited Creativity 3-Limited Business </ul>
  55. 56. Characteristics : <ul><li>Rich user experience
  56. 57. User participation
  57. 58. Dynamic content
  58. 59. Metadata
  59. 60. Web standards
  60. 61. Scalability
  61. 62. Openness
  62. 63. Collective intelligence </li></ul>
  63. 66. Web 3.0 <ul><li>Next generation of web
  64. 67. Web 3.0 browser will act like personal assistant
  65. 68. Understood information over web
  66. 69. Instead of only keyword search ,it employs context based search
  67. 70. An approach to implement web 3.0 is semantic web
  68. 71. Ontologies </li></ul>
