Podcast--you may have heard the word, but you don't know what it means. I can assure you that if you have kids in high school or college, they will know. It is relatively new technology that often, but not always, uses the iPod to capture and display either audio or video. According to Wikipedia, the free online encyclopedia, podcasting is a method of distributing multimedia files, such as audio programs or music videos, over the Internet for playback on mobile devices and personal computers.
