Summary

AJAX allows pages to send or receive data from servers without reloading entire pages. jQuery packs the capability with compact APIs such as $.ajax(), $.get(), and .load(). With AJAX, the page section can be partially updated to make the user experience feel faster.

The page is kept alive because only a fraction of the content is updated
jQuery provides $.ajax() as the main request gateway
Successful callbacks are used to process the returned data
