RSS (Really Simple Syndication) or syndication permitted to be included in a single file all the new content on a website, which is both useful to users and referencing.
The standard allows RSS to be informed about news from a website, without having to consult. The RSS file in XML format, also known as RSS feeds, or RSS channel, allows to describe in summary form the content of a site. This file is maintained automatically updated to always contain the latest information to disseminate. Sites by providing such a flow often affix a logo RSS for this type: 
on their pages, or even the same symbol will be visible in the right corner of the address fields (Firefox) or on the navigation bar (IE7) web browser.
The use of these flows allows a user through a reader or feed aggregator, to view many sites without having to visit them, and so to read the latest content published by these sites without disclosing any personal information.
Moreover, a webmaster can also use these feeds to syndicate content, then automatically publish it on their site different information from other sites. This will effectively generate many links “deep” for the site at the source of the stream. These links will be beneficial to complete referencing, ie including the inner pages or deep site generating the flow.
