RSS, which stands for Really Simple Syndication or Rich Site Summary, is a web feed format that allows users to access updates to online content in a standardized, computer-readable format. It enables publishers to syndicate frequently updated information, such as news headlines, blog posts, or podcast episodes, allowing users to easily keep track of new content without having to visit each site individually. By subscribing to an RSS feed using an RSS reader, users can receive a consolidated view of updates from various sources, making it a valuable tool for efficiently managing information in the digital age.

The RSS format consists of XML files containing summaries of content along with metadata like publication dates and authorship information. This simplicity allows for compatibility across various platforms and devices, making it accessible for both publishers and consumers. By promoting the distribution of content directly to users, RSS fosters a more decentralized and user-driven media landscape, empowering individuals to curate their own information streams based on their interests.
