RSS stands for Rich Site Summary (often referred to Really Simple Syndication). It`s a defined standard based on XML with the main purpose of gathering and delivering information and updates of web based content. Website owners attach RSS feed to contents on their website to which, later, web users, if interested to follow updates on this content, can subscribe to feeds. Nowadays a great number of websites offer RSS feed subscription. Whether a website offers the option for subscription can be easily identified as an orange square with a broadcast motif, usually on the top of the web page.
