Peer-To-Peer network is the model in which each computer functions as both client and/or a server. All the nodes have the equal role of server and clients at the same time. There is no dedicated server and there is no hierarchy among computers.
- In this network, when a first computer wants to send message to third computer, then first must be passed through second computer. If the address matches to second computer then it accepts the message otherwise it discards it and forwards to the next computer. When the address is matched then communication is started. When communication starts established between two computers then other channels remain free.
