Definition
An RSS feed reader is a software or service that allows you to aggregate content from multiple websites into one place. Essentially, instead of visiting dozens of sites to read news or updates, an RSS reader automatically collects articles published by the sites you subscribe to, via their RSS (or Atom, a similar format) feeds.
How it works
- A website publishes an RSS feed, which is an XML file containing headlines, links, summaries, and sometimes full content
- The RSS reader periodically downloads this feed
- The user sees all updates in a single interface, without having to visit individual sites.
