ASP

Active Server Pages (ASP) programming is writing code to facilitate ASP functionality on websites. Such functionality includes the delivery of dynamic, database-driven content to website viewers without taxing the server-side system. ASP programming involves writing ASP files and HTML files. The ASP code is placed within the HTML pages, enclosed in special tags. When you need to make changes in the ASP programming code, you need change only the ASP files; the HTML files, which do nothing but go and get the ASP files' coding, need not be changed.

ASP files have a file extension of .asp

ASP.NET

Unlike ASP, ASP.NET uses the Common Language Runtime (CLR) provided by the .NET Framework. This CLR manages execution of the code we write. ASP.NET code is a compiled CLR code instead of interpreted code (ASP). CLR also allows objects written in different languages to interact with each other. The CLR makes developement of Web applications simple.

Advantages Using ASP.NET

ASP.NET drastically reduces the amount of code required to build large applications ASP.NET makes development simpler and easier to maintain with an event-driven, server-side programming model ASP.NET pages are easy to write and maintain because the source code and HTML are together The source code is executed on the server. The pages have lots of power and flexibility by this approach The source code is compiled the first time the page is requested. Execution is fast as the Web Server compiles the page the first time it is requested. The server saves the compiled version of the page for use next time the page is requested The HTML produced by the ASP.NET page is sent back to the browser. The application source code you write is not sent and is not easily stolen
