TOPOLOGY
Topology refers to the physical or logical arrangement of computers or nodes in a network. The factors
that determine the type of topology are cost, flexibility and reliability. There are five different types of
topologies. 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 is very difficult.
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 may 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 easy compared to other topologies
such as bus as it involves a connection only to the central node.
