RSS (Really Simple Syndication) allows users to subscribe to sources of information and receive brief updates in a feed. When browsing the web, software will automatically detect RSS feeds on sites and display an orange RSS badge. To use RSS, a user needs a computer, internet connection, and an RSS reader to aggregate feeds from sites like news organizations in a single place and receive updates wherever they are. RSS files are simple text files hosted on websites that use RDF to describe content updates.
