What are the advantages of rerendering?

Hi,

The "rerender" attribute specifies a list of elements that should be dynamically updated using Visualforce's AJAX library. When a "rerender" attribute is specified, the entire page will no longer refresh, but only a portion of the page identified by the elements named in the "rerender" attribute. This may be desirable, as the entire page will no longer turn white as the page is reloading (noticable on slower connections), but will instead be updated client-side. For slower connections, it is recommended that you use the "status" attribute in addition to the "rerender" attribute so that the user will see a notification that their request is being handled.

Rerender is used to refresh a particular section of the visualforce page. We have to just mention the id of the page section (in the Rerender attribute) that needs to be refreshed.
