Really Simple Syndication (RSS) is a web specification used for content distribution. RSS feed content can be accessed by installing a news reader. You can subscribe to an RSS feed by right-clicking on the "RSS" orange button next to the feed, selecting the "Copy Shortcut" option from the menu, and pasting it into the news reader of your choice.
Podcasts use the RSS format and provide you with a way to listen to audio files at your convenience. You can either listen to podcasts directly from your browser or you may choose to subscribe to them using a program (iTunes or Juice) that syncs them up with your portable MP3 player. You can watch our tutorials if you need help installing and using iTunes and Juice.
