Really Simple Syndication
RSS content can be read using software called an "RSS reader," "feed reader", or an "aggregator." The user subscribes to a feed by entering the feed's link into the reader or clicking an RSS icon in a browser that begins the subscription process for the online. The reader often checks the user's subscribed feeds for new content, downloading any updates it finds. This content is stored in a standard XML file that many different computers and programs can understand. This file tells the programs how to show the content to the user.
