What is a Podcast?

March 21, 2011

You might have heard people talking about podcasts. Do you know what it is? By definition, a podcast is actually an audio file which lives on the Internet. However, it is different from a regular audio file like an MP3. A podcast has special information attached to it which allows a listener to get updated with the latest pieces of information. One needs to subscribe to such a service. It is called an RSS (really simple syndication) feed. It is mainly a way for applications, such as iTunes, to automatically look for new episodes of a podcast whenever a new update comes up. You can think of a podcast as a radio show that comes to you. You can download the podcast file of your interest whenever you want to.
