What is podcasting ?

It is the process of making an audio file in MP3 format of content that is available to download. This process is called as podcasting .
 
A podcast is an episodic series of digital media files which a user can set up so that new episodes are automatically downloaded via web syndication to the user's own local computer or portable media player.

The word arose as a portmanteau of "iPod" (a brand of media player) and "broadcast". Thus, the files distributed are typically in audio or video formats, but may sometimes include other file formats such as PDF or ePub.

The distributor of a podcast maintains a central list of the files on a server as a web feed that can be accessed through the Internet. The listener or viewer uses special client application software on a computer or media player, known as a podcatcher, which accesses this web feed, checks it for updates, and downloads any new files in the series. This process can be automated so that new files are downloaded automatically, which may seem to the user as though new episodes are broadcast or "pushed" to them. Files are stored locally on the user's device, ready for offline use.Podcasting contrasts with webcasting or streaming which do not allow for offline listening, although most podcasts may also be streamed on demand as an alternative to download. Many podcast players (apps as well as dedicated devices) allow listeners to adjust the playback speed.

Podcasting is a method of distributing multimedia files (such as audio programs or music videos) over the Internet, using either the RSS or Atom syndication format, for playback on mobile devices and personal computers. "Podcast" can refer to both the content and the method of delivery. The host or author of a podcast is often called a podcaster. While podcasters' websites may also offer direct download or streaming of files, a unique feature of podcasts is that they can be downloaded automatically using software capable of reading RSS or Atom feeds. The term podcasting comes from "iPod" and "broadcasting".
