RSS Feeds

RSS feeds are a utility that allow users to subscribe to sites on the internet that update regularly, so rather then checking sites for updates, the RSS feeds will inform you the moment an update as occurred which will save time for the user.

RSS feeds are not limited to sites, for example Itunes also use RSS feeds for a lot of podcasts and such that allow listeners to download podcasts at their leisure with ease as the Feed will produce a type of "shopping list" of downloads that have been uploaded to that feed.
