Hello friend, A podcast is a collection of digital media files which is distributed over the Internet using syndication feeds for playback on portable media players and
personal computers.
In general, these files contain
audio
or
video,
but also could be
images,
text,
PDF,
or any file type.
  The content provider begins by making a file (for example, an
MP3
audio file) available on the Internet through some known
Uniform Resource Identifier.
This is usually done by posting the file on a
webserver
; however,
BitTorrent
trackers also have been used. The files may be available to the general public or may only be available to certain users. The content provider then announces the existence of that file by referencing it in another file known as the feed. The feed is a list of the URLs by which
episodes of the podcast may be accessed. This list is usually published in
RSS
format (although
Atom
can also be used), which provides other information, such as publish date, titles, and accompanying text descriptions of the series and each of its episodes.
