TOPOLOGY
Topology refers to the geometric 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.

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.
