Question

Whats the difference between pod-casting and instant messenger communication?

Answer 1

postcasting is a one way communication from the creator who wants to express his/her view, news and information and the listener who subscribe/download the podcast.

Instant messenger communication involve two or more people communicating between each other in real time.

Answer 2

They are different programs, Instant messenger is more for chat and podcast is more for media

A podcast is a series of digital-media files, which are distributed over the Internet using syndication feeds for playback on portable media players and computers. The term podcast, like broadcast, can refer either to the series of content itself or to the method by which it is syndicated; the latter is also called podcasting. The host or author of a podcast is often called a podcaster.

The term is a portmanteau of the words "iPod" and "broadcast", the Apple iPod being the brand of portable media player for which the first podcasting scripts were developed (see history of podcasting). Such scripts allow podcasts to be automatically transferred to a mobile device after they are downloaded. As more devices other than iPods became able to synchronize with podcast feeds, the term was redefined by some parties as an abbreviation for the backronym "Personal On Demand broadCASTING".

Though podcasters' web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital media formats by its ability to be syndicated, subscribed to, and downloaded automatically when new content is added, using an aggregator or feed reader capable of reading feed formats such as RSS or Atom.

Answer 3

Podcasting is when you put video/audio on the web so it can be streamed/downloaded by the masses. It's synonymous with webcasting. Technically speaking, podcasting is supposed to be media that can also be downloaded and viewed on an iPod (thus the "pod" in "podcasting"), but the term is used in a more general sense to mean webcasting.

Instant messenger communication is usually between only two people through typed, video, or voice chat. Sometimes there can be more than two people through chat rooms, though generally typed messaging is only available. There are sites that do video and text chat on a larger scale, but those are typically separate web services. Also, instant messenger communication by nature is only "instant" and isn't generally downloadable for viewing later on iPods or similar players.

Answer 4

Podcasting is either live streaming or prerecorded audio, typically in the form of a radio show or music. Instant messaging is simply a live means to communicate between you and another.

AOL Instant Messanger, for instance is a Instant Messaging program, whereas  something like iTunes can play podcasts.
