Types of Network Topology
Features : of Bus Topology: 1) Transmits data only in one direction.
2)Connected to a single cable
Disadvantages of Bus Topology
Cables fails then whole network fails. 2. If network traffic is heavy or nodes are more the performance of the network decreases. 3. Cable has a limited length. 4. It is slower than the ring topology.
Advantages of Bus Topology:-
Easy to expand joining two cables together.
Features of Ring Topology :-
A number of repeaters are used for Ring topology with large number of nodes, because if someone wants to send some data to the last node in the ring topology with 100 nodes, then the data will have to pass through 99 nodes to reach the 100th node. Hence to prevent data loss repeaters are used in the network.
The transmission is unidirectional, but it can be made bidirectional by having 2 connections between each Network Node, it is called Dual Ring Topology.
In Dual Ring Topology, two ring networks are formed, and data flow is in opposite direction in them. Also, if one ring fails, the second ring can act as a backup, to keep the network up.
Data is transferred in a sequential manner that is bit by bit. Data transmitted, has to pass through each node of the network, till the destination node.
Advantages of Ring Topology :
Transmitting network is not affected by high traffic or by adding more nodes, as only the nodes having tokens can transmit data.
Cheap to install and expand
Disadvantages of Ring Topology
Troubleshooting is difficult in ring topology. 2. Adding or deleting the computers disturbs the network activity. 3. Failure of one computer disturbs the whole network.
Advantages of Hybrid Topology 1. Reliable as Error detecting and trouble shooting is easy. 2. Effective. 3. Scalable as size can be increased easily. 4. Flexible.
Features of Hybrid Topology 1. It is a combination of two or topologies 2. Inherits the advantages and disadvantages of the topologies included
Disadvantages of Hybrid Topology 1. Complex in design. 2. Costly.
Disadvantages of Tree Topology 1. Heavily cabled. 2. Costly. 3. If more nodes are added maintenance is difficult. 4. Central hub fails, network fails.
Features of Tree Topology 1. Ideal if workstations are located in groups. 2. Used in Wide Area Network.
Advantages of Tree Topology 1. Extension of bus and star topologies. 2. Expansion of nodes is possible and easy. 3. Easily managed and maintained. 4. Error detection is easily done.
It is cost effective.
Used in small networks.
Cable required is least compared to other network topology.
It is easy to understand.
