There are more than 30 types of "casting" formats today, that include use of video and audio content that can be shared between a sender and a receiver. Among these types, webcasts represent AV (audio video) content that could be live or delayed, and is broadcast on the Web. Webcasting is a form of "push technology," which takes place when a central server initiates the request to transmit information.
Podcasts, on the other hand, deal exclusively with audio files that are shared to users via RSS, and then uploaded to a digital player like Soundcloud or hardware like iPod. It is worth noting that many people confuse podcasting with "voice recording." Recording oneself making a lecture of learning materials is not a podcast.
