P2P File Sharing

File sharing involves distributing or providing access to digitally stored information, an example would involve computer programs.

P2P File sharing is the same thing as file sharing, however, the difference is it is strictly peer to peer.

Some examples of P2P file sharing would involve bulletin board systems, which is used in many universities.  (BlackBoard).  Another would be Hotline and chat rooms, developed for peers to communicate with other peers.
