A podcast is a web feed of audio or video files placed on the internet for download, and the term also refers to the content of that feed.

Some podcasting websites will offer direct download of their files, but the subscription feed of automatically delivered new content is what distinguishes a podcast from a simple download or real-time streaming of audio and video. This site offers you the option to subscribe to a series or listen online to an individual podcast from that series.

Podcasting is the distribution of audio or video files, such as course lectures, radio programs or videos, over the internet using RSS (Real Simple Syndication) for listening on mobile devices (like iPods) and personal computers.

So, how is this different than having an audio or video file posted to a website? For NJIT, podcasting is really all about two things-
1. Creating audio or video content for an audience (students) that want to use course materials with personal control over when/where/how they use it.
2. Allowing students to subscribe to a course and having the downloading of that course's podcasts automated by software such as iTunes.
