3When was AJAX coined / developed ?Nobody invented AJAX. But,the computer scientist Jess James Garret first coined the term "Ajax" in 2005.Note: The key technology: XMLHttpRequest used in AJAX was developed by Microsoft for its Internet Explorer 5.0 for Windows as an ActiveX object in 1999.
When was Silverlight coined / developed ?Microsoft released its first version of Silverlight in 2007.
4AJAX mainly relies on what technology / framework?Ajax relies on the XMLHttpRequest object.Using it, Ajax typically retrieves data from servers and can do so asynchronously. This means Ajax can retrieve data without disrupting the behaviors and displays of existing WebPages.Silverlight mainly relies on what technology / framework ?Unlike Ajax, which relies on the XMLHttpRequest object, Silverlight relies on the .NET framework. This framework provides the common language runtime (CLR) run-time environment, enabling Silverlight for running code and providing services that simplify the developmental process. Specifically, Silverlight's .NET framework and CLR environment allow developers to execute the same compiled code on servers as well as clients.
5What is the main purpose of AJAX ?Developers typically use Ajax for creating interactive website features that end-users can access through Web browsers.
What is the main purpose of Silverlight?In comparison, developers typically use Silverlight for creating image- and video-based social media content that end-users can stream -- or download in real-time. Developers can also extend the functionality or richness of their Ajax features by using Silverlight, but not vice-versa.
6Whether AJAX needs to be installed in .NET ?From ASP.Net 3.5 onwards, AJAX has been integrated into the .NET Framework. Hence, there is no need to install in .NET.Whether Silverlight needs to be installed in the system?Silverlight plugin needs to be installed in our system for better browsing experience.
Development Benefits:Silverlight improves work-flow by separating the visual, user-interface aspects of website development from the back-end, business-logic aspects of development.
9Whether AJAX provides Cross-platform support ?Ajax is a cross-platform technique that can be used on wide range of different operating systems, computer architectures.Whether Silverlight provides Cross-platform support ?Silverlight is not fully platform independent tool. It only supports Windows OS, Linux OS using Moonlight and Mac OS.
