Ring Topology
- all computers are connected with a loop.
- if one node fail the entire network will failed.




Mesh Topology
- the realiability is very high because if one node fails it may not affect.






Star Topology
- all node are connected in a central node.
- if the central node fail all the connections will failed.





Bus Topology
- node are connected to a communication line.




Tree Topology
- connected to a parent node but when it fails the entire
connection may failed.
