AJAX allows for asynchronous data retrieval and updating of parts of a web page without reloading the entire page. It uses a combination of technologies including XML, JavaScript, CSS, HTML and the XMLHttpRequest object. The XMLHttpRequest object makes asynchronous HTTP requests to the server in the background and retrieves data from the server. This allows updating parts of the web page without interrupting the user's operation.
