Bus
-
The computers (nodes) are connected to a single cable on which data can be sent, called the bus.
The bus has terminators on each end, which are needed to close each end of the cable.
-
Ring
The transmission of data is simple as packets travel in one direction only, so no collisions.
-
-
If any of the computer systems fail, the ring is broken and data cannot be transmitted efficiently

Extra hardware required, such as a hub

Mesh
Each node relays data for the mesh network. All mesh nodes cooperate in the distribution of data in the network.
This is very reliable as it can 'self-heal' by reconfiguring around broken paths. This network is complex, expensive and difficult to set up. A large part of the network may be redundant
