Peer-to-Peer Technology

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 electronically bi-directional communication, in contrast to client/server systems that require continuous polling of the client on the server, a technique with very low efficiency. The number of software plattforms that enable P2P communication is increasing heavily, and stimulates people to share information and digitalize our bi- or multi-directional communcation.
