Difference between Mesh Topology and Bus Topology

1. Mesh Topology: Mesh topology is a type of network topology in which each computer is connected to every other computer in the network. It is the most fault-tolerant network topology as it has multiple connections. In a mesh topology, each computer is connected to the other computer by a point-to-point link. If there are n components then each component is connected to n-1 other components i.e a mesh topology with n components will have n(n-1)/2. Mesh topology can be of two types namely full mesh topology and partially mesh topology. Mesh topology is one of the most robust and reliable topologies.

2. Bus Topology: Bus topology is a type of network topology in which all the devices are connected to a single cable which is called the backbone of the network. It consists of a terminator at each end of the cable. The network cable is responsible for the communication between the devices and when the data reaches the end of the cable it is removed by the terminator from the data line. It is the easiest network topology when the devices are to be connected linearly.
Differences between Mesh Topology and Bus Topology:

Mesh Topology	Bus Topology
Mesh topology is a topology where each device is connected to every other device in the network.	Bus topology is a topology where each device is connected to a single cable which is known as the backbone.
In Mesh topology failure of one device will not cause the break in transfer of data.	In Bus topology the failure of the network cable will cause the whole network to fail .
Mesh topology can manage high amount of traffic in the network as multiple devices can transmit data.	Bus topology can not effectively manage high amount of traffic as if there is high traffic then performance of the network is affected.
Mesh topology is more costly than bus topology.	Bus topology is less costly as compared to mesh topology.
Mesh topology is more complex to understand as compared to bus topology.	Bus topology is relatively easier to understand.
Mesh topology transmits data faster than bus topology.	In Bus topology the data is transmitted slower as compared to mesh topology.
Mesh topology provides more security than bus topology.	Bus topology provides less security as compared to mesh topology.
Huge cabling is required in mesh topology.	Less cabling is required in bus topology.
The implementation of mesh topology is complicated.	The implementation of bus topology is simple.
It can manage heavy traffic so fewer chances of collision.	There are chances of collisions when high traffic is observed in a network.
Mesh topology is robust and reliable.	Bus topology is less robust and reliable as compared to mesh topology.
It is preferred to use where reliability is more important like in military organizations and many more.	It is preferred for LAN networks.
