peer-to-peer (P2P)

A type of computer network that consists of two or more computers that pool their individual resources such as disk drives, CD-ROMs, and printers. These shared resources are available to every computer in the network, while each two of them communicate in a session.

In contrast, a client-server network consists of multiple client computers connecting to a single, central server computer. The server is a host running one or more server programs that share their resources with the clients.
