What is network topology
The term network topology is used to denote the arrangement of the network devices in a computer network. Network topology may be used to show physical or logical arrangement of devices inside a computer network.
A network topology diagram allows a network engineer to visualize how the devices are connected in the network. Network topology diagrams thus helps a network engineer to maintain and troubleshoot the network.
As a network engineer, you should know some of the common network topologies. Some of the common network topologies are bus topology, star topology, ring topology, dual ring topology, fully-mesh topology, partially mesh topology, hybrid topology, point-to-point topology and tree topology.
