~ A daisy- chained like Christmas light. Each node is along the same backbone and information is sent from a node to travel along the backbone until it reaches it destination node ~

~ Ring Topology ~

Like a bus network, rings have the nodes daisy- chained. The difference is that the end of the network comes back around to the first node, creating a complete circuit.

~ Star Topology ~

In a star network, each node is connected to a central device called a hub. The hub takes signal that comes from any node and passes it along to all the other nodes in the network.

~ Mesh Topology ~

In a mesh topology, each node is connected to every other node in the network. The primary advantage of this topology is its reliability.
