4. What is Podcasting ? An audio recording posted online, much like a short radio show. Think of a podcast as a radio show. Each show consists of a series of individual episodes that you can listen to how you want — on your PC, using your MP3 player, or with just a web browser.

5. Definition of podcasting Podcasting is a term used to describe a collection of technologies for automatically distributing audio programs over the Internet using a publisher/subscriber model. It differs from earlier online delivery of audio because it automatically transfers the digital media files to the user’s computer for later use. http://en.wikipedia.org/wiki/Podcasting

6. Podcasting “Podcasting” combines two words: “iPod” and “broadcasting”. You don’t need an iPod to listen to a podcast! Any PC will be fine! Alternative terms would be “audio blog” or “audioblogging” “Personal On-Demand” & broadcasting, giving: POD-casting

7. Podcasting - What It Is A podcast is really just an mp3 audio file that is distributed via an RSS feed (by linking the mp3 file to a blog posting or to a web page). Current “podcatching” software, such as iTunes, allows the user to subscribe to an RSS feed; the software will automatically download new podcasts when they become available. iTunes

8. Podcasting – The Listener Subscribes to the RSS feed for the blog using “podcatching” software (such as iTunes) ONE TIME ONLY New podcasts are automatically downloaded to the user’s PC – and can be played on the computer The mp3 files can be “synched” to a portable mp3 player, such as an iPod, for anytime, anyplace listening – mobile learning – “m-learning”.
