Bus
- All devices are attached to one cable
- Single-point failure
Ring
- Similar to bus, but ends are attached
- Not susceptible to single-point failure
Star
- All nodes are attached to central device
- Susceptible to failure of central device, but easy to identify cable failure
Tree
- Similar to the star, but with a hierarchical structure
Mesh
- Devices link to multiple other devices
- A failure has little impact on the network, but costly
