What is an RSS feed?

RSS belongs to the family of XML formats and is intended to describe the latest updates of Internet resources, such as news, publications of new articles, updates on blogs, etc. Almost any text content that can be divided into separate parts can be provided in RSS format. Usually, RSS provides a brief description of new information appearing on the site and a link to its full version. A resource in the RSS format is usually called an RSS channel or RSS feed.
