RSS (Really Simple Syndication) is the easiest way to aggregate and distribute Web content like news from your favourite website/s. RSS/XML feeds can update headlines on your computer software as they change through sections. This is possible because an RSS reader will aggregate content from your favourite preset channels and post the same in XML format on your desktop.
To begin getting an RSS feed, you will need a feed aggregator, also called an RSS reader installed on your machine( click here for a list of free RSS readers available on the web)
'Extensible markup language', or XML as it is popularly known, splits information (be it content or images) using markers like 'headlines', 'introductions', 'footnotes', or just about anything else, making it easier for computers to locate and collate specific information.
