System Peer to peer network is a system that not only connect "tip" one another, but the ends are dynamically interconnected and participate in directing traffic, information communication, processing, and assignment of bandwidth-intensive division, where if the system This does not exist, these tasks are usually performed by a central server.
Peer to peer network can be balanced continuously without increasing search time and the call addresses without having to use a centralized source. They use machines that use the device end-users (end users) because these sources are always walking toward the proportion of the network goals. Each addition of a new edge to the network adds more potential for more powerful processing and greater bandwidth to the network. Plus, because its resources are decentralized, the second generation (2G) from P2P networks have succeeded in virtually eliminating all costs associated with large centralized infrastructure.
