"Really Simple Syndication"
The abbreviation RSS stands for "Really Simple Syndication" or "Rich Site Summary". Both mean the same thing, namely a newsfeed. RSS is a practical XML standard for providing news reports or text information for other computers.
With an special RSS newsreader or an add-on to your web browser, you can automatically download and read the most important headlines of a feed. Before doing this, you have to subscribe to it.
On every website / every weblog containing one of these symbols ( or ) or a link with the designation "RSS", "RDF", "Channel" or "XML", you can subscribe to dynamic book marks or newsfeed (for newsreaders).
