The term distributed system typically refers to a set of entities, called nodes, connected by point-topoint communication links. The set of nodes together with the set of links form a network, which is usually represented by a graph. The term ?system" is used to reflect the fact that nodes evolve over time, i.e., they change their internal states according to some local interaction-rule, which is applied in every time step (i.e. round).
