Ajax stands for Asynchronous JavaScript and XML. There are two prime benefits of Ajax:-
It send’s only necessary data to the server. For instance let’s say you have 4 textboxes and on a submit button you want to only send two text box data, Ajax helps in the same.
The second benefit is it’s asynchronous. In other words when you click on submit button and until the server processes the request you can do other activities on the site. For instance when you click on send email and until the email is sent , you can start composing a new email at the back ground.
The above question is taken from the bestselling c# and .NET interview question book written by Shivprasadkoirala and published by BPB publication.
