• Ring Topology • A configuration that connects all nodes in a closed loop
on which messages travel in one direction .• Star Topology• A configuration that centers around one node to which all
others are connected and through which all messages are sent .
• Bus Topology• All nodes are connected to a single communication line
that carries messages in both directions . • Mesh Topology• In Mesh Topology each node is connected to every other
node.
