Ring

• Unidirectional transmission links form closed loop
• Token Ring and FDDI
• Similar to the Star topology, however there’s a device called a Multistation Access Unit (MAU)
• MAU works the same as a hub, but with Token Ring networks instead of Ethernet networks
• These networks were originally designed to serve large, bandwidth-intensive applications

Star

• Nodes connected to a central LAN or a junction box called a hub or a concentrator at the center of the network
• Provides reliability and often used by Bus and ring topology as the physical connection

Tree – branches can have multiple nodes

Mesh – all nodes are connected to every other node
