RSS is Really Simple Syndication, a way to subscribe to regularly updated content like websites and receive summaries of new information. RSS uses XML formats to deliver headlines and summaries to the user through an RSS reader, allowing them to efficiently keep up with multiple sources in one place rather than visiting each site individually. RSS feeds are simple text files that follow Resource Description Framework guidelines to indicate to aggregators how to retrieve and display the updates. Many blogging platforms and tools make it easy to generate RSS feeds without requiring technical coding skills.
