A "feed" is Web content (data) that is stored in a standardized format, so that the content can be shared (A.K.A syndicated) with other sites. RSS (Really Simple Syndication) is the most popular of the standardized formats. Feeds are useful for sharing content that is frequently updated such as news stories or blog postings.  Feeds contained standardized fields such as "Title", "Subject", "Description" and "Date" so that the content can be sorted, categorized and classified according to any of these fields.
