Extensive rich multimedia content and extensive user interaction in Web 2.0 calls for technologies that will send and receive only limited relevant data from the server that has dynamic capabilities to process and upload data, and simple API’s to integrate with other applications built in other technologies. Some of the technologies that fulfilled these criteria and brought about the change in internet are:
Asynchronous JavaScript: It is web based programming language, which along with features of object oriented language has the features of dynamic typing and run time evaluation too.
Extensible Markup Language (XML): This language that is developed from set of rules specified by W3C for encoding documents in machine readable form. The data packets are encoded in this format to send data across browser and server.
Adobe Flash: This is multimedia platform which is used to add multimedia to web pages. Flash manipulates vector and raster graphics to provide animation of text, drawing and still images. It supports bidirectional streaming of audio and video. It also contains object oriented language “Action scripts”.
Adobe Flex: It is software development tool kit to develop and deploy cross platform rich Internet applications based on Adobe Flash.
Ajax: It’s a group of interrelated web development methods used on client side (browser) to create interactive web application. Ajax uses HTML and CSS for presentation, DOM for dynamic handling of data, XML for interchange for data, XMLHttpRequest object for asynchronous communication and javascript to bring all above together.
RSS: A data format that is used to publish frequently updated works like blogs, news etc. This data format is essentially built upon XML.
Mashups: It is a web page or application that combines data, presentation or functionality from two or more sources. Technologies like RSS and Ajax are extensively to build mashups.
Other technologies in web2.0 space work on same lines as above mentioned ones. Its these technologies that have brought about change in web domain; which we call as web2.0.
