Peer-to-peer (P2P) networking

The basic definition of a P2P network is a network where groups of independent computers called nodes are interconnected, sharing data without the assistance of any centralized servers. It is an architecture on top of the internet. Participants or nodes in this type of network are called peers because they are all equal and have equal responsibility within the network. Since there are no special nodes in a P2P network, each peer is both a service provider and a consumer.
