AJAX: Asynchronous JavaScript And XML

 
AJAX is an acronym for Asynchronous JavaScript And XML.

 
AJAX is not a programming language. but simply a development technique for creating interactive web applications.

The technology uses JavaScript to send and receive data between a web browser and a web server.

The AJAX technique makes web pages more responsive by exchanging data with a server behind the scenes, instead of reloading an entire web page each time a user makes a change.

With AJAX, web applications can be faster, more interactive, and more user friendly.

AJAX uses an XMLHTTPRequest object to send data to a web server, and XML is commonly used as the format for receiving server data, although any format including and plain text can be used.

AJAX Is A Browser Technology

AJAX is a technology that runs in your browser. It uses asynchronous data transfer between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages.

The technology makes Internet applications smaller, faster and more users friendly.

AJAX Is Based On Open Standards

AJAX is based on the following open standards:

• JavaScript
• XML
• HTML
• CSS

The open standards used in AJAX are well defined, and supported by all major browsers. AJAX applications are browser and platform independent. (Cross-Platform, Cross-Browser technology)
