There's a pretty big difference between the two. A
quick google search should yield quite a few results.
In short:
ASP: Always-dynamically compiled, weakly-typed, non-managed web scripting engine using VBScript (typical) or JavaScript.
ASP.NET: Optionally pre-compiled, strongly-type, managed web development framework based on the .NET framework using many .NET languages (C#, J#,
VB.NET, etc.).
