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.
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.
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.
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.
