RSS stands for "Really Simple Syndication" and is a format for distributing and gathering content from sources across the web, such as news sources and online magazines. This content (or information) is fed to the user instead of them having to seek it out. The user can at a glance, find the content they are most interested in.
To sign up for RSS news feeds, copy and paste the link into your RSS Reader. RSS news readers (or aggregators) download and display news via a stand-alone program, or a browser plug-in. Many free and commercial news aggregators are available for download.
