Network Topology
Star Topology
Nodes are connected to a host computer or hub that controls communication between devices. the hub or host computer regenerates any signal that it receives and passes it on. Only the intended recipient computer acts on the message.
All nodes have independent connections to the host. A cable failure on one branch of the network will continue to function normally and the failure will be easy to isolate.
| Advantages | Disadvantages |
|---|---|
| · Adding new devices is easy and doesn't disrupt the rest of the network. | · It requires a lot of cables. |
| · There are no data collisions. | · It is expensive to install. |
| · There is less traffic on the network. | · It is expensive to install. |
| · A cable failure on one branch of the network will be easy to isolate. | · Needs professionals to maintain and up keep. |
