is ajax a backend technology to fetch data?

I want to know if ajax is a backend technology to fetch data or it’s only considered as a frontend technology. I’ve searched for it in google but did not get any clear and straight answer.

>Solution :

Ajax is not a technology.

It is terminology given to the act using JavaScript embedded in a webpage (client-side code) to make an HTTP request (to a backend) and processing the response without leaving the page.
