What is Podcast?

Podcast is a combination of "i pod" and board casting originally through the RSS feeding. It can downland any media like power point, fashion movies, popular music , and so on into it. It uses not only in i pod or i Tunes, it also can use digital audio player from 2005. These informations could found in Wikipedia if you are interested. However, if you are not familiar with RSS as me, I find two videos from Youtube to introduce RSS: the first one introduced the concept of RSS and show me an example of Google reader; the second one introduced the example of Freereader. And these two examples below is very easy to understand even I am not very familiar with the computer.
