Podcasts are convenient ways for the average person to listen to or even watch a program or anything else at the drop of a dime. Podcasts are technically the actual processes of making media files as well as audio files available on the web and allows software to automatically download the files that are wanted for viewing or listening by the client. Podcasts are in tracked by really simple syndication or an RSS file.
This particular type of file is a XML based format that is used for content distribution. A media aggregator is also a commonly used term in which allows a person to download the audio files from any place on the internet straight to the desktop of the computer.
