peer-to-peer - A definition

Peer-to-peer, or abbreviated P2P, refers to a logical structure of network where the communication is done more from one node to another instead of many nodes depending on a central point in the network. Peer-to-peer networks may or may not depend on a central node in the network. The Internet is an example of a peer-to-peer network, but recently, peer-to-peer has begun to refer applications in which users can use the Internet to exchange music or other files with each other directly or through a mediating server. Kazaa Media Desktop is probably the most widespread file-sharing program using a peer-to-peer structured network.
