The term "Podcasting" is an acronym for "Pod" that comes from " iPod ", and the union of "Broadcast" which means "broadcast, transmission or broadcast", the "ing" is the gerund of the English language. It is also called (iPod streaming) because it originated to be listened to through an iPod. Its creation originated in order to have the possibility of listening to music and being able to play videos on portable players.
A Podcasting is a format under which a digital audio (multimedia) file is created, generally audio, although videos can also be played, which can be distributed through a syndication system or file such as (the RRS channel); and in this way it will be able to subscribe and be treated by specific programs that allow its download and reproduction when the user wishes. Although a simpler way of perceiving it is taking it as if it were a recording of a radio program and that its only distribution is through the internet since it is not transmitted through the radio waves. And actually that's the structure of a Poscat (that of a radio show).
In order to have or listen to one of these files, it is necessary to subscribe to a Podcast (since in most cases they are on a blog, and there they are uploaded physically as MP3 data files or other formats), We reproduce them directly from the web or download it to our computer or portable player as we can synchronize them so that we can listen to them wherever and whenever we want.
