RSS stands for "Really Simple Syndication". It is also known as a News Feed and is in essence a type of online journal that compiles and distributes new content from websites the user would like to be kept up to date on (often with a link to the relevant website page).
How does RSS work?
In order to view an RSS feed you must subscribe to it. This can be done easily through your Internet browser. You will be shown the feed and asked if you would like to subscribe. Once subscribed you will be able to view the news feed in your browser’s RSS viewer.
***NOTE: A great RSS viewer is available for free if you have a gmail account through google.com
