INTERNET APPLICATION

Rich Internet Applications (RIAs) are web applications that have many of the characteristics of desktop applications, typically delivered either by way of a site-specific browser, via a browser plug-in, or independently via sandboxes or virtual machines.[1] Adobe Flash, Java and Microsoft Silverlight are currently the three top frameworks, with penetration rates around 95%, 80% and 45% respectively.

XML AND RSSAdvocates of "Web 2.0" may regard syndication

of site content as a Web 2.0 feature, involving as it does standardized protocols, which permit end-users to make use of a site's data in another context (such as another website, a browser plugin, or a separate desktop application). Protocols which permit syndication include RSS (Really Simple Syndication — also known as "web syndication"), RDF (as in RSS 1.1), and Atom, all of them XML-based formats. Observers have started to refer to these technologies as "Web feed" as the usability of Web 2.0 evolves and the more user-friendly Feeds icon supplants the RSS icon.

WEB APLSWeb 2.0 often uses machine-based interactions such as REST and SOAP.

Often servers use proprietary APIs, but standard APIs (for example, for posting to a blog or notifying a blog update) have also come into wide use. Most communications through APIs involve XML or JSON payloads.

Web Services Description Language (WSDL) is the standard way of publishing a SOAP API and there are a range of Web Service specifications.

See also EMML by the Open Mashup Alliance for enterprise mashups.

WORKINGThe working of it is the way of performing the group

of technology they are ajax,java,adob flash,xml,..etc the client will send a request to the server are separated

from data coming back to the page is perfomed by the ajax.

The data fetched by an Ajax request is typically formatted in XML or JSON format, two widely used structured data formats. Since both of these formats are natively understood by JavaScript, a programmer can easily use them to transmit structured data in their web application. 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,

USAGE

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,[23] including Library 2.0,[24] Social Work 2.0,[25] Enterprise 2.0, PR 2.0,[26] Classroom 2.0, Publishing 2.0, Medicine 2.0, Telco 2.0, Travel 2.0, Government 2.0,[27] and even Porn 2.0.
