    JavaScript is a programming language

    Ajax is shorthand for “Using JavaScript to send or receive information to/from a webserver without leaving the current page”

    jQuery is a library of functions (written in JavaScript) that perform some commonly desired things so that author’s don’t need to reinvent some common wheels.

    1. Javascript

    A language that comes with your browser. It allows you to show an alert box, the one that you need to press Ok, validate forms, on the client, or without change the page. Usually, it is stopped by an alert, confirm, etc box.

    2. jQuery

    A library code made with Javascript, that make easier to program Javascript and AJAX. You can download it on jquery.com .

    3. AJAX

    Asynchronous Javascript And XML. Which means that with a help from a programming language like PHP, ASP.NET and etc. it can work changing data without refresh the whole page, just the part of the data will be refreshed.
