asynchronous communication between user interfaces and web
server. So the advantages of using Ajax are asynchronous

AJAX - Asynchronous Javascript and XML.

In a nutshell, AJAX is used for making PARTIAL request.

Update Panel, Tab Control, Etc... are just examples of things that you can do with AJAX, but not limited to those things. You can be more creative, because in general, you will use AJAX, check the server response and do something based on that response with or without changing the entire contents of the page.

Restriction: Cross-Domain scripting.
