4. What is a Podcast?

A podcast is a media file (primarily audio and video) that is delivered by syndication feeds (RSS) over the Internet to mobile devices or computers. The author or host of the podcast is called a podcaster, whilst the name Pod is derived from the iPod portable music player brand.

How to listen to or watch a Podcast?

Podcasts are designed to be cross compatible, they can be viewed on most desktop computers and laptops via client side or online players. By the nature of their name they were developed for listening to on Apple's phenomenally successful iPods. Recent developments in mobile phone technology have facilitated the download of Podcasts to subscribers' mobile phones, Blackberries and similar mobile devices.
