P2P

P2P stands for Peer to Peer sharing,which brought a revolution in utilising the internet's bandwidth. It is estimated that one bit of every three bits on internet is used by p2p. This means the bandwidth consumed by a single p2p client equals the normal browsing of a humdred to thousand people around the world.
The software that popularised p2p is Bit Torrent. The server-client model is simplified and customised , with the implementation of BT protocol. But unfortunately most of the material that is shared on P2P is illegal and pirated.The advantage of BT protocol is even the peer computer can act as seed(who shares the content).
