Silverlight is a new technology which is base on .Net Framework and cross-browser , cross-platform.It can provide a rich interactive application(RIA) for the web.Of course it can run outside of the browser on your desktop also.It is easy for you to use Extensible Application Markup Language (XAML)  to design UI.You can load controls,make animations,draw graphics,fabricate three-dimensional objects with XAML which sounds wonderful.
 
Commonly it like flash player pugin ,Little download and easy installation but more strong than flash.It streams video and audio with hign quality even in 720p HDTV video modes.Also you can drag and drop ,zoom,turn graphics in the browser.Refresh data partialy but not whole the page which is like ajax.
