What is podcasting?
“Podcast” is derived from the terms “iPod” and
“broadcast.” (You don’t need an iPod).
Podcasts are media files (usually mp3 or video
files) that are published to web sites, and then
syndicated. Users subscribe to the feeds and the
podcasts are downloaded automatically. Users
may also download some podcasts manually.
Example:

Terminology
• RSS – Really Simple Syndication - is a family of Web
feed formats used to publish frequently updated works
such as blog entries, news headlines, and podcasts in a
standardized format.
• Aggregator – “In computing, a feed aggregator, also
known as a feed reader, news reader or simply
aggregator, is client software or a Web application which
aggregates syndicated web content such as news
headlines, blogs, podcasts, and vlogs in a single location
for easy viewing.”
(from http://en.wikipedia.org/wiki/RSS_aggregator)
Terminology
A podcast can be downloaded and
delivered online via RSS feed (webfeed)
subscriptions.
Podcatchers are special RSS aggregators
that transfer the files to your computer
iTunes and Juice are aggregators or
podcatchers (podcast receivers).
