.NET is a framework to develop software applications. It is designed and developed by Microsoft and the first beta version was released in 2000.
It is used to develop applications for the web, Windows, and phones. Moreover, it provides a broad range of functionalities and support.
ASP and ASP.NET are one of the best server-side technologies. Both technologies enable computer code to be executed by an Internet server.
When a browser requests an ASP or ASP.NET file, the ASP engine reads the file, executes any code in the file, and returns the result to the browser.
