What is ASP.Net ?

ASP stands for Active Server Pages. ASP is an open, compile-free application environment in which you can combine HTML, scripts, and reusable ActiveX server components to create dynamic and powerful Web-based business solutions. Active Server Pages enables server side scripting for IIS with native support for both VBScript and JScript.
ASPs are Web pages that contain server-side scripts in addition to the usual mixture of text and HTML tags. Server-side scripts are special commands you put in Web pages that are processed before the pages are sent from the server to the web-browser of someone who's visiting your website. All ASP pages are given a .aspx extension. The servers that support ASP are Internet Information Server (IIS) & Microsoft Personal Web Server. Unline normal HTML pages you can view ASP pages without running a web server.
When a ASP.net page is compiled it’s translated into MSIL.
