More self-tutoring about computer networks: the tutor shares the definition of peer-to-peer network.
A network in which any computer is directly connected to any other, rather than through a server. The premise of P2P seems to be that the members are physically connected by wire.
The arrangement could be two computers connected, for example, by USB. It could also be a larger set of computers all connected along one main rail.
