Imagine computer networks as highways in the sky. What vehicles would travel
on these highways, and what destinations would they reach?

TOPOLOGY Campus Area Network
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 these in detail.
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

difficult, and a failure in the main cable
can bring down the entire network.
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.
