P2P is the abbreviation of Peer-to-Peer computing. It's a kind of network with information exchange between computers which are at the same time a client and a server. Each one hosts, downloads and uploads data so there's a weak centralization of information and the load of the transfers is distributed. These data can be files (texte, images, videos), continuous flow (streaming) or calculation between connected computers (like SETI@Home).
