Peer-to-peer (P2P)
computing or networking is a
distributed application architecture that partitions tasks or work loads
between peers. Peers are equally privileged, equipotent participants in
the application. They are said to form a peer-to-peer network of nodes.
Peers make a portion of their resources, such as processing power,
disk storage or network bandwidth, directly available to other network
participants, without the need for central coordination by servers or
stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client-server
model in which the consumption and supply of resources is divided.
Emerging collaborative P2P systems are going beyond the era of peers
doing similar things while sharing resources, and are looking for
diverse peers that can bring in unique resources and capabilities to a
virtual community thereby empowering it to engage in greater tasks
beyond those that can be accomplished by individual peers, yet that are
beneficial to all the peers
