Question

I want to understand how facebook notifications work. When someone like your posts, comments, send message, etc, facebook sends a notification as soon as the event done. I want to know if there is any server side script or events fired when users hit like button, posts, send messages, etc.
I need to know how to implement something like that using jquery and php to use on my wbsite.
