Web 2.0

  1. 1. Web 2.0 <ul><li>Introduction </li></ul><ul><li>Characteristics </li></ul><ul><li>Technology </li></ul><ul><li>Working </li></ul><ul><li>Usage </li></ul>
  2. 2. Introduction <ul><li>Web 2.0- is commonly associated with web applications that facilitate interactive information sharing,interoperability,user-centered design,and colloboration on the world wide web. </li></ul><ul><li>Web 2.0 include web-based communities, hosted services, web applications, social-networking sites, video-sharing sites, wikis, blogs, mashups, and folksonomies. </li></ul>
  3. 3. Characteristics <ul><li>Web2.0 allows users to do more than retrive information. </li></ul><ul><li>They can built an interactive facilities of web 1.0 to provide network as platform. </li></ul><ul><li>Users can own the data on a Web 2.0 site and exercise control over that data. </li></ul><ul><li>The characteristics of Web 2.0 are: rich user experience, user participation, dynamic content, metadata, web standards and scalability. </li></ul>
  4. 4. Characteristics <ul><li>Web 2.0 Rich user experience, user participation, dynamic content, metadata, web standards and scalability. </li></ul><ul><li>The concept of Web-as-participation-platform captures many of these characteristics. </li></ul><ul><li>Bart Decrem, a founder and former CEO of Flock, calls Web 2.0 the participatory Web and regards the Web-as-information-source as Web 1.0 . </li></ul>
  5. 5. Technology <ul><li>Web 2.0 sites provide users with information storage, creation, and dissemination capabilities that were not possible in the environment now known as Web 1.0. </li></ul><ul><li>Features of Web 2.0 are </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>
  6. 6. Working <ul><li>The client-side/web browser technologies typically used in Web 2.0 development are Asynchronous JavaScript and XML (Ajax). </li></ul><ul><li>Adobe Flash and the Adobe Flex framework, and JavaScript/Ajax frameworks such as Yahoo! UI Library, Dojo Toolkit, MooTools, and jQuery. </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><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>
  7. 7. Working <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><ul><li>Adobe Flex is another technology often used in Web 2.0 applications. </li></ul><ul><li>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>
  8. 8. Usage <ul><li>The popularity of the term Web 2.0, along with the increasing use of blogs, wikis, and social networking technologies. </li></ul><ul><li>It has led many in academia and business to coin a flurry of 2.0s,including Library 2.0, Social Work 2.0, Enterprise 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>
