Asynchronous JavaScript and XML or AJAX, is a group of interrelated web development techniques used for creating interactive web applications or rich Internet applications
In other words Ajax is a way of programming for the Web that gets rid of the hourgl***.
Applications created with Ajax use an engine that acts as an intermediary between a user's browser and the server from which it is requesting information.
Instead of loading a traditional Web page, the user's browser loads the Ajax engine, which displays the page the user sees. The engine continues to run in the background, using JavaScript to communicate with the Web browser. User input or clicking on the page sends a JavaScript call to the Ajax engine, which can respond instantly in many cases.
If the engine needs additional data, it requests it from the server, usually using XML, while it is simultaneously updating the page.
Ajax combines several programming tools including
Ajax allows content on Web pages to update immediately when a user performs an action unlike an HTTP request, during which users must wait for a whole new page to load.

- JavaScript
- Dynamic HTML (DHTML)
- Extensible Markup Language (XML)
- Cascading style sheets (CSS)
- Document Object Model (DOM)
- Microsoft object
- XMLHttpRequest.
