What is RSS?
RSS is an acronym for Really Simple Syndication, which is an XML-based format for content distribution. RSS feeds can be read using software called an "RSS reader,” "feed reader," or "aggregator," which can be web-based, desktop-based, or mobile-device-based. Most browsers can act as an RSS reader.
What are podcasts?
Podcasts are digital media files, either audio or video, that are typically delivered via a Web feed (RSS feed); however, they can also be directly downloaded. Users can subscribe to the RSS feed to receive regular updates when new episodes are released using a podcasting software application. There are many free applications available for download; iTunes is one of the more popular applications. Podcasting software allows users to play audio and video files, manage their files, and transfer them to an mp3 player.
