P2P

In its simplest form, P2P is a connection between two or more users without the use of a separate server.  In other words this is a way for these users to connect, share, and impact a shared data. P2P is basically a file sharing device, probably used most of the time to distribute content such as films or music such as "The Dark Knight", which struggled with the battle of illegal content (Digital Pirates Winning Battle with Studios).  P2P was also used by such programs such a Napster and Pirate Bay.
