RSS
RSS (Really Simple Syndication) is a feed format that lets a site publish its latest posts in a standard way, so apps can read them automatically.
Think of it like
Like subscribing to a magazine: new issues come to you, instead of you checking the newsstand every day.
Example
A blog publishes an RSS feed at /feed.xml; a reader app checks it and shows you new articles as they appear.
Why it matters
RSS quietly powers podcasts, news readers, and “follow” features across the open web, with no algorithm or login required.
