No, not necessarily every web site is implementing Ajax.Ajax is the use of the XMLHttpRequest concept in JavaScript for you to communicate asynchronously with all the server and also retrieve details (text, html code, XML, JSON, etc.) back minus the need to refresh your entire page.

It is being exercised a lot more by website applications in making them seem a tad bit more like pc applications (quicker responses and less waiting around for the particular user).This helps make applications sound more n accessible and user-friendly.
