BUS Topology
Bus topology is a network type in where every computer and network device is connected to single cable.
Features of Bus Topology
It transmits data only in one direction. Every device is connected to a single cable
Advantages of Bus Topology
It is cost effective. Cable required is least compared to other network topology. Used in small networks. It is easy to understand. Easy to expand joining two cables together.
Disadvantages of Bus Topology
Cables fails then whole network fails. If network traffic is heavy or nodes are more the performance of the network decreases. Cable has a limited length. It is slower than the ring topology.
TREE Topology
It has a root node and all other nodes are connected to it forming a hierarchy. It is also called hierarchical topology. It should at least have three levels to the hierarchy.
Features of Tree Topology
Ideal if workstations are located in groups. Used in Wide Area Network.
Advantages of Tree Topology
Extension of bus and star topologies. Expansion of nodes is possible and easy. Easily managed and maintained. Error detection is easily done.
Disadvantages of Tree Topology
Heavily cabled. Costly. If more nodes are added maintenance is difficult. Central hub fails, network fails.
