Rich Site Summary stands for "site summary" or "concise and useful site summary" and allows you to stay up to date with the latest news and headlines from your favorite sites or blogs without having to visit them.
The main uses of RSS are the following two: - Displaying the latest titles of other websites on your website or vice versa (subscribing to new content) - Receiving the latest content from favorite sites using special software (browsing the web more efficiently)
Without RSS, you would have to check your favorite sites every day to see what's new. But with this technology, you can see multiple sites together in an RSS aggregator (RSS reader) and see the titles of recent posts from the sites without having to go back.
What is RSS Reader? RSS Reader is an electronic RSS reader software. Now there are many software in this field that can be downloaded to read RSS. But recently, internet browsers have also been equipped with an electronic RSS reading system. RSS reader software includes Thunderbird and Google Reader.
