Bus Topology
Ring Topology
In this topology, all the nodes are connected in a circular
path. The messages travel in clockwise or anti-clockwise
direction. Any damage to the cable of any node or device
can result in breakdown of the whole network.
Ring Topology
Star Topology
In this topology, central node acts as a hub to which all
the other nodes are connected. As compared to the bus
topology, star topology requires more devices and cables.
The addition of a new node to a star topology is difficult as
it involves a connection all the way to the central node.
Star Topology
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. But its
major disadvantage is that if the root node fails
to operate, the entire network is inoperable.
Tree Topology
Mesh Topology
In this topology, every single node in a network is connected to
all the other nodes or computers in the network. There is minimal
chances of breakdown in this topology. This topology is mostly
used in LANs.
