| Star topology | Bus topology |
| All nodes are connected to central hub | All nodes are connected with single cable called backbone |
| It is more expensive | It is less expensive |
| Chances of data collision is low | Chances of data collision is high |
| Failure of a node may affect entire network | Failure of a node does not affect entire twork |
| Data transmission is fast | Data transmission is low |
