RSS makes it possible for people to keep up with web sites in an automated manner that can be piped into special programs or filtered displays. [3]The benefit of RSS is the aggregation of content from multiple Web sources in one place. RSS content can be read usingsoftwarecalled an "RSS reader", "feed reader" or an "aggregator", which can beweb-basedordesktop-based. A standardizedXMLfile format allows the information to be published once and viewed by many different programs. The user subscribes to a feed by entering the feed's link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The RSS reader checks the user's subscribed feeds regularly for new content, downloading any updates that it finds and provides auser interfaceto monitor and read the feeds.The initials "RSS" are used to refer to the following formats:*.ReallySimpleSyndication (RSS 2.0)RDFSite Summary (RSS 1.0 and RSS 0.90)*.Rich Site Summary (RSS 0.91).RSS formats are specified usingXML, a generic specification for the creation of data formats.
