In normal web applications, every request made by the user reloads the entire page.
This includes form submission, button clicks, and data requests.
When the above form is submitted, the browser sends data to the server and reloads the complete page.
All existing data, scroll position, and page state are lost.
In AJAX-based communication, the request is sent in the background.
The page remains active and does not refresh.
With AJAX, only the required data is sent and received.
The rest of the page continues running without interruption.
Normal page load is simple but slow and outdated.
AJAX provides faster interaction, smoother experience, and better performance.
Most modern websites avoid full page reload and depend heavily on AJAX for user interaction.
Understanding this difference helps developers decide when and why AJAX should be used in real projects.
