Types of Topologies
What is Network Topology?Network topology is the arrangement of the elements of a communication network. Network topology is the topological structure of a network and may be depicted physically or logically
The 1st type of network topology is:
BUS Topology
Bus topology is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints, then it is called Linear Bus topology.
The 2nd type of network topology is:
RING Topology
It is called ring topology because it forms a ring as each computer is connected to another computer, with the last one connected to the first. Exactly two neighbours for each device.
The 3rd type of network topology is:
STAR Topology
In this type of topology all the computers are connected to a single hub through a cable. This hub is the central node and all others nodes are connected to the central node.
The 4th type of network topology is:
MESH Topology
It is a point-to-point connection to other nodes or devices. All the network nodes are connected to each other. Mesh has
n(n-1)/2 physical channels to link n devices.
There are two techniques to transmit data over the Mesh topology, they are :
- Routing
- Flooding
MESH Topology: Routing
In routing, the nodes have a routing logic, as per the network requirements. Like routing logic to direct the data to reach the destination using the shortest distance. Or, routing logic which has information about the broken links, and it avoids those node etc. We can even have routing logic, to re-configure the failed nodes.
MESH Topology: Flooding
In flooding, the same data is transmitted to all the network nodes, hence no routing logic is required. The network is robust, and the its very unlikely to lose the data. But it leads to unwanted load over the network.
The5th type of network topology is:
HYBRID Topology
It is two different types of topologies which is a mixture of two or more topologies. For example if in an office in one department ring topology is used and in another star topology is used, connecting these topologies will result in Hybrid Topology (ring topology and star topology).
These are all the types of Network Topologies hope it helps!
Also thank you for viewing my blog! It helps alot. :)
