This document describes several types of communication networks: circular networks connect nodes in a circle, wheel networks connect a central node to surrounding nodes, chain networks connect nodes linearly, Y networks connect a central node to multiple separate nodes, mesh networks connect all nodes redundantly, and hybrid networks combine elements of the other types.
