Really Simple Syndication (RSS) is a way to subscribe to a source of information, such as a Web site.
RSS works by having the website author maintain a list of notifications on their website in a standard way. This list of notifications is called an "RSS Feed". Many Blog services automatically create RSS Feeds. For Websites, RSS Feeds can be created manually or with software(such as Software Garden, Inc.'s ListGarden).
The RSS Feed that is created is an XML file that lives on a Webserver. Once RSS feed is ready on web server, RSS Feeds waits for an RSS Reader to subscribe to them. The RSS Feed Reader reads the RSS Feed file and displays it. That is, the RSS Reader displays only new items from the RSS Feed. An RSS Feed Reader reads the RSS feed file, finds what is new, converts it to HTML, and displays it.
