Web2 0

  1. 1. WEB 2.0 <ul><li>SSKCET </li></ul><ul><li>The latest updates of IT talents. </li></ul>
  2. 2. INTRO ABOUT WEB 2.0 <ul><li>The term &quot;Web 2.0&quot; is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design,and collaboration on the World Wide Web. </li></ul><ul><li>A Web 2.0 site allows its users to interact with each other as contributors to the website's content, in contrast to websites where users are limited to the passive viewing of information that is provided to them. </li></ul>
  3. 3. EXAMPLES OF WEB 2.0 <ul><li>web-based communities, </li></ul><ul><li>hosted services, </li></ul><ul><li>web applications, </li></ul><ul><li>social-networking sites, </li></ul><ul><li>sharing sites, </li></ul><ul><li>Wikis, </li></ul><ul><li>Blog, </li></ul><ul><li>Mashups and folksonomies. </li></ul>
  4. 4. CHARACTERISTICS <ul><li>Web 2.0 websites allow users to do more than just retrieve information. They can build on the interactive facilities of &quot;Web 1.0&quot; to provide &quot;Network as platform&quot; computing, allowing users to run software-applications entirely through a browser. </li></ul>
  5. 5. CHARACTERISTICS <ul><li>These sites may have an &quot;Architecture of participation&quot; that encourages users to add value to the application as they use it. </li></ul><ul><li>The concept of Web-as-participation-platform captures many of these characteristics. Bart Decrem, a founder and former CEO of Flock, calls Web 2.0 the &quot;participatory Web&quot; and regards the Web-as-information-source as Web 1.0. </li></ul>
  6. 6. CHARACTERISTICS <ul><li>Rich user experience, user participation, dynamic content, metadata, web standards and scalability. Further characteristics, such as openness, freedom and collective intelligence by way of user participation, can also be viewed as essential attributes of Web 2.0. </li></ul><ul><li>This requires what is sometimes called Radical Trust by the management of the website. </li></ul>
  7. 7. TECHNOLOGY A VIEW <ul><li>FEATURES AND TECHNIQUES </li></ul><ul><li>Search </li></ul><ul><li>Links </li></ul><ul><li>Authoring </li></ul><ul><li>Tags </li></ul><ul><li>Extensions </li></ul><ul><li>Signals </li></ul>
  8. 8. FEATURES AND TECHNIQUES <ul><li>Search - Finding information through keyword search. </li></ul><ul><li>Links - Connects information together into a meaningful information ecosystem using the model of the Web, and provides low-barrier social tools. </li></ul><ul><li>Authoring - The ability to create and update content leads to the collaborative work of many rather than just a few web authors. </li></ul>
  9. 9. FEATURES AND TECHNIQUES <ul><li>Tags - Categorization of content by users adding &quot;tags&quot; - short, usually one-word descriptions - to facilitate searching, without dependence on pre-made categories. Collections of tags created by many users within a single system may be referred to as &quot;folksonomies&quot; (i.e., folk taxonomies). </li></ul><ul><li>Extensions - Software that makes the Web an application platform as well as a document server. </li></ul>
  10. 10. FEATURES AND TECHNIQUES <ul><li>Signal - The use of syndication technology such as RSS to notify users of content changes. </li></ul><ul><li>While SLATES forms the basic framework of Enterprise 2.0, it does not contradict all of the higher level Web 2.0 design patterns and business models. And in this way, the new Web 2.0 report from O'Reilly is quite effective and diligent in interweaving the story of Web 2.0 with the specific aspects of Enterprise 2.0. The report makes many sensible around starting small with pilot projects and measuring results, among list. </li></ul>
  11. 11. WORKING OF WEB 2.0 <ul><li>The client-side/web browser technologies typically used in Web 2.0 development are Asynchronous JavaScript and XML (Ajax), Adobe Flash and the Adobe Flex framework, and JavaScript/Ajax frameworks such as Yahoo! UI Library, Dojo Toolkit, MooTools, and jQuery. Ajax programming uses JavaScript to upload and download new data from the web server without undergoing a full page reload. </li></ul>
  12. 12. WORKING OF WEB 2.0 <ul><li>To permit the user to continue to interact with the page, communications such as data requests going to the server are separated from data coming back to the page (asynchronously). </li></ul><ul><li>The data fetched by an Ajax request is typically formatted in XML or JSON (JavaScript Object Notation) format, two widely used structured data formats. </li></ul>
  13. 13. WORKING OF WEB 2.0 <ul><li>Since both of these formats are natively understood by JavaScript, a programmer can easily use them to transmit structured data in their web application. </li></ul><ul><li>When this data is received via Ajax, the JavaScript program then uses the Document Object Model (DOM) to dynamically update the web page based on the new data, allowing for a rapid and interactive user experience. </li></ul>
  14. 14. WORKING OF WEB 2.0 <ul><li>Adobe Flex is another technology often used in Web 2.0 applications. Compared to JavaScript libraries like jQuery, Flex makes it easier for programmers to populate large data grids, charts, and other heavy user interactions. </li></ul><ul><li>Applications programmed in Flex, are compiled and displayed as Flash within the browser. </li></ul>
  15. 15. WORKING OF WEB 2.0 <ul><li>In addition to Flash and Ajax, JavaScript/Ajax frameworks have recently become a very popular means of creating Web 2.0 sites. </li></ul><ul><li>At their core, these frameworks do not use technology any different from JavaScript, Ajax, and the DOM. </li></ul><ul><li>On the server side, Web 2.0 uses many of the same technologies as Web 1.0. </li></ul>
  16. 16. WORKING LANGUAGES <ul><li>PHP </li></ul><ul><li>Ruby </li></ul><ul><li>Perl </li></ul><ul><li>Python </li></ul><ul><li>JSP </li></ul><ul><li>ASP </li></ul><ul><li>To share its data with other sites, a web site must be able to generate output in machine-readable formats such as XML, RSS, and JSON. </li></ul>
  17. 17. USAGE OF WEB 2.0 <ul><li>The popularity of the term Web 2.0, along with the increasing use of blogs, wikis, and social networking technologies, has led many in academia and business to coin a flurry of 2.0s, including Library 2.0, Social Work 2.0,WEB 2.0, PR 2.0,Classroom 2.0, Publishing 2.0, Medicine 2.0, Telco 2.0, Travel 2.0, Government 2.0, and even Porn 2.0. </li></ul><ul><li>Many of the other proponents of new 2.0s mentioned here use similar methods. </li></ul>
  18. 18. WEB BASED APPS <ul><li>Ajax has prompted the development of websites that mimic desktop applications, such as word processing, the spreadsheet, and slide-show presentation. </li></ul><ul><li>Several browser-based &quot;operating systems&quot; have emerged, including EyeOS and YouOS. </li></ul><ul><li>They mimic the user experience of desktop operating-systems,features and applications like to a PC environment, as well as the added ability of being able to run within any modern browser. </li></ul>
  19. 19. TRADEMARK <ul><li>In November 2004, CMP Media applied to the USPTO for a service mark on the use of the term &quot;WEB 2.0&quot; for live events. On the basis of this application, CMP Media sent a cease-and-desist demand to the Irish non-profit organization IT@Cork on May 24, 2006, but retracted it two days later. The &quot;WEB 2.0&quot; service mark registration passed final PTO Examining Attorney review on May 10, 2006, and was registered on June 27, 2006. The European Union application was refused on May 23, 2007. </li></ul>
