Network Topologies – Types of Network Topologies with Examples

Network Topologies:- 


Network topologies describe the ways in which the weather of a network are mapped. They describe the physical and logical arrangement of the network nodes.
The network topology of a network refers to the configuration of cables, computers, and different peripherals

Different Types of Topologies:-

  • Bus Topology
  • Star Topology
  • Ring Topology
  • Mesh Topology
  • Tree Topology
  • Hybrid Topology

Bus Topology:-

All the nodes (file server, workstations, and peripherals) on a topology square measure connected by one single cable.

A topology consists of a main run of cable with an eradicator at every finish. All nodes (file server, workstations, and peripherals) square measure connected to the linear cable.

Popular on LANs as a result of they’re cheap and simple to put in.

  • It is low-cost, straightforward to handle, and implement.
  • Require less cable 
  • It is best fitted to tiny networks.


  • The cable is restricted. This limits the number of stations which will be connected.
  • This topology will perform well just for a restricted range of nodes.

Ring Topology:-

In a ring network, each device has specifically 2 neighbors for communication functions.
All messages travel through a hoop within the same direction.
A failure in any cable or device breaks the loop and might take down the complete network.
To implement a hoop network we have a tendency to use the Token Ring technology
A token, or tiny knowledge packet, is endlessly passed around the network. once a tool must transmit, it reserves the token for the following trip around, then attaches its knowledge packet thereto
  • Very orderly network wherever each device has access to the token and therefore the chance to transmit.
  • Easier to animal disease than a Bus Network
  • Good communication over long distances
  • Handles a high volume of traffic
  • The failure of one node of the network will cause the complete network to fail.
  • The movement or changes created to network nodes affects the performance of the complete network.

Star Topology:-

In a star network, every node (file server, workstations, and peripherals) is connected to a central device known as a hub.

The hub takes a symbol that comes from any node and passes it on to any or all the opposite nodes within the network.

Data on a star network passes through the hub, switch, or concentrator before continuing to its destination.

The hub, switch, or concentrator manages and controls all functions of the network.

The star reduces the prospect of network failure by connecting all of the systems to a central node.

  • Easy to manage
  • Easy to find issues (cable/workstations)
  • Easier to expand than a bus or ring topology.
  • Easy to put in and wire. 
  • Easy to observe faults and to get rid of elements.
  • It requires additional cable than a linear topology.
  • If the hub or concentrator fails, nodes hooked up square measure disabled. 
  • More expensive attributable to the value of the concentrates.
