Although I know the terms I used to forget the differences sometimes...So just to maintain a place for reference...Thanks all for your answers.
ASP, Active Server Pages (now referred to as ASP Classic) is a server-side scripting environment that predates .Net and has nothing to do with it
ASP pages are usually written in VBScript, but can be written in any language supported by the Windows Scripting Host - JScript and VBScript are supported natively, with third-party libraries offering support for PerlScript and other dynamic languages.
.Net is a framework for managed code and assemblies
.Net code can be written in any language that has an CIL compiler.
CLR, Common Language Runtime, is the core runtime used by the .Net framework
The CLR transforms CIL code (formerly MSIL) into machine code (this is done by the JITter or by ngen) and executes it.
ASP.Net is a replacement for ASP built on .Net
ASP.Net pages can be written in any .Net language, but are usually written in C#.
