The Node Network is a collection of interconnected computers communicating over a network of equally privileged computers (i.e., there are no central authoritative computers). The node network is sometimes referred to as a peer-to-peer (P2P) network.
A Node is an individual computer that participates as an equal within the node network. A node is sometimes referred to as a peer. Nodes receive input, perform one or more operations on those inputs, and returns an output.
