Ring Topology
This topology connects all nodes in a circular path. The messages travel
in clockwise or anti-clockwise directions. Any damage to the cable of any
node or device can result in a breakdown of the whole network.
Star Topology
In this topology, the central node acts as a hub to which all the other
nodes are connected. As compared to the bus topology, the star
topology requires more devices and cables. The addition of a new
node to a star topology is easy compared to other topologies, such as
bus, as it involves a connection only to the central node.
Tree Topology
In this topology, nodes are connected as branches of a
tree, where hub acts as a root node. It is very simple in
nature, as it is easier to add new or remove the faulty
nodes. However, its major disadvantage is that if the root
node fails to function, the entire network is inoperable.
Mesh Topology
This topology connects every node in a network to every other node or
computer in the network. In this topology, there are minimal chances
of breakdown. This topology is mostly used in LANs.
