NOTE: This lesson uses jQuery as the interface for basic AJAX work. By no means is AJAX a product of jQuery and you do not need jQuery to utilize AJAX.
AJAX allowed webpages to continually request resources without the need to reload the entire webpage. This allowed users to stay on a webpage longer and interact with other various features of that page as the requests were made. The asynchronicity that this brought revolutionized the previous web era, where all dynamic changes required a complete trip to the server for a full refresh of the page with the new content based on the user's intent.

Jesse James Garrett, in 2005, coined the term AJAX which stood for Asycronous JavaScript And Xml. A year later it received its first W3C draft specification.AJAX allowed webpages to continually request resources without the need to reload the entire webpage.
