ASP stands for Active Server Pages. It is a development framework used for building web pages. ASP was introduced in 1998 by Microsoft as its first server-side scripting language. The file extension of ASP pages are .asp and are normally written in VBScript. It is an old but still powerful tool for making dynamic web pages. ASP is a technology (much like PHP) for executing scripts on a web server.

Example: 

html




<!DOCTYPE html>
<html>
 
<body>
    <%response.write("Welcome to GeeksforGeeks!")%>
</body>
 
</html>                   

Output: 

Welcome to GeeksforGeeks!

ASP.NET: ASP.NET was released in 2002 by Microsoft as a successor to ASP. It is also a server-side web framework, open-source, which is designed for the generation of dynamic web pages. The file extension of ASP.NET pages is .aspx and is normally written in C# (C sharp). The latest version of ASP.NET is ASP.NET 4.6.

Example: 

csharp




@{
    var rank = 50;
}
<html>
<body>
@if (rank < 60)
{
    <p>Welcome to GeeksforGeeks!</p>
}
</body>
</html>

Output: 

Welcome to GeeksforGeeks!
