what is the difference between ASP and ASP.NET?

ASP:
Is not truly Object Oriented; it uses more of a top-down programming style, where code execution begins at the top and executes down to the end. You can use functions, sub-routines, classes and other objects, but it isn't OO.
You are limited to using either the Visual Basic or JavaScript scripting languages.
All variables are global of type variant, which like its counterpart in VB6, is an object that can be any object type, from a string to an integer to a Word application object.


ASP.NET:
Is Object Oriented, uses the event-driven model, where all your code executes in response to an event, like a mouse-click, or a Page Load, etc.
You can use many different languages to write your code: Visual Basic, C#, J#, Ruby, even Visual RPG. All code is compiled to use the same Common Language Runtime (CLR) that resides in the .NET Framework.
Variables are strongly typed, and the same scoping rules that apply in any recent, major programming language.
