The latest version of Microsoft's Active Server Pages technology (ASP) is ASP.NET.

What is ASP?
ASP is a server side scripting technology and it enables
scripts (embedded in web pages) to be executed by an Internet
server.
ASP:
is the Microsoft Technology
stands for Active Server Pages
is a program that runs inside the IIS
IIS:
stands for the Internet Information Services
comes as a free component with the Windows 2000
is also a part of Windows NT 4.0 Option Pack

PWS:
is a smaller - but fully functional - version of the IIS
can be found on your Windows 95 or 98 CD
What is an ASP File?
An ASP file is same as an HTML file
An ASP file can contain HTML,text,scripts, and XML
In an ASP file,scripts are executed on the server
An ASP file has file extension ".asp"
How does it works?
When a browser requests an HTML file, the server returns
the corresponding file
IIS passes the request to the ASP engine on the server,when a browser requests an ASP file.
The ASP engine executes the scripts in the file and reads the file, line by line.
Finally, the ASP file is returned to the browser in the form of
plain HTML page.
It would help to have a basic
understanding of Microsoft's ASP technology,before you study ASP .NET.

The .NET Framework contains common class libraries - like ADO.NET, ASP.NET and Windows Forms - to provide advanced standard services that can be integrated into a variety of computer systems and a common language runtime.
The .NET Framework provides an easy integration between a number of different development languagesa feature-rich application environment, simplified development and .
The .NET Framework is language neutral and Currently it supports C++, C#, Visual Basic, and JScript (Microsoft's version of JavaScript).
For the .NET Framework,Microsoft's Visual Studio.NET is a common development environment.
Advantages of Using ASP.NET
1.Improving Development productivity by
reducing the lines of code to be written
by 70% and also most of the frequently required
code is now available out of the box.
2.To connect to new devices that may
emerge in the future ,ASP.NET is making easier to use with
existing devices like Web browsers, PDAs,
Cell phones and so on with a potential.
3. Increasing scalability and performance
for developing fast web
applications platforms by providing
facilities such as caching.
4. Simplifying the management and administration
of web applications
5.For Internet Service
providers,it Provides enhanced hosting
opportunities
6.It ensures 100% backward
compatibility.
The team split the process of
enhancement into three different
parts:--Application services, Page
effects and Rich controls. They focused
on each of these parts to come up with
an application development platform that
is extremely and exciting developer
friendly.
