Description:
Since Napster appeared in 1999, various Peer-to-Peer (P2P) file sharing applications (e.g., WinMX, KaZaA, Gnutella, Freenet, winny) have emerged one after another. The secret behind this technology is that it enables electronical bi-directional communication, in contrast to client/server systems that require continuous polling of the client on the server, a technique with a very low efficiency, and forces centralization of knowledge. The number of software platforms that enable P2P communication is increasing heavily, and stimulates people to share information and digitalize our bi- or multi-directional communcation. New and useful applications stimulate the use of the internet.
