RSS Feeds are simple XML-based systems that allows users to subscribe to their favourite websites.
Using RSS, webmasters can put their content into a standardized format, which can be viewed and organized through RSS-aware software or automatically conveyed as new content on another website.
A program known as a feed reader or aggregator can check a list of feeds on behalf of a user and display any updated articles that it finds. It is common to find web feeds on major websites and many smaller ones.
