Topology or structure is the layout of the connection formed between computers. The efficiency
and reliability of a network is determined by its structure. In other words, Topology refers to the
geometric arrangement of computers or nodes in a network. Let us learn about them.
Bus Topology
In this topology, all the nodes are connected to a single common path. It is simple and easy
to maintain. Additional nodes can be connected at any point along its length. The major
disadvantage of this topology is that fault detection in this topology is very difficult.
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.
Star Topology Ring 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
