        The full form of AJAX is Asynchronous JavaScript and XML. AJAX is a web development technique for creating interactive web applications. AJAX uses XHTML for content and CSS for presentation, along with Document Object Model (DOM) and JavaScript for dynamic content display. AJAX is a technology with the help of which the information is brought from the server to the page without refreshing the page. AJAX is used a lot in creating a dynamic website because all the processing of AJAX happens in the backend and information can be brought from the server to the page without reloading the page. AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page.

Note.

AJAX is not a programming language it is just a combination of XMLHttpRequest object (to request data from a web server), JavaScript and HTML DOM (to display or use the data).

These are the main features of Ajax, That's why all web developers use Ajax.

  1. It makes web pages faster.
  2. It is free of server technology.
  3. Ajax enhances web page performance.
  4. In Ajax, there is no need to press any submit button and reload the whole website.
  5. There is no need to reload the whole page in Ajax, in which only part of the page is reloaded.
  6. Apart from receiving the XMLHTTP object, all processing is the same for all browser types as it uses JavaScript.
  7. Ajax is used to develop faster and more interactive web applications.

Advantages of ajax

  1. AJAX minimizes the traffic travel between the client and the server.
  2. AJAX communicates over the HTTP protocol.
  3. AJAX works independently of server technology.
  4. Aside from getting the AJAX XMLHTTP object, all processing is the same for all browser types as it is used in JavaScript.
  5. AJAX is used to develop faster and more interactive web applications.
  6. AJAX-based applications use very little server bandwidth as there is no need to reload all the pages.

Disadvantages of ajax

  1. AJAX does not run on all browsers.
  2. Security protection is low in AJAX applications.
  3. Anyone can see the source code written for AJAX.
  4. This can increase design and development time.
