RSS stands for Really Simple Syndication. RSS provides a fast and effective way of keeping up-to-date with your favourite sites through web feeds.
Whenever new content is added to the sites, these feeds are automatically updated.
An RSS reader scans the feeds for any updates, and displays the latest headlines, plus a brief synopsis and a link that takes you to the source site.
This process saves you from constantly revisiting your favourite sites to look for new content.
