What is Topology  Network Topology is the arrangement of the various elements links, nodes, etc. of a computer network. it is the topological structure of a network and may be depicted physically or logically. Topologies are divided into two types. One is called physical topology & another one is logical topology. Physical topology is the placement of the various components of a network, including device location and cable installation, while logical topology illustrates how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two networks.   Topology There are a number of reasons to understand about Topology: The network topology impacts performance The network topology is a factor in determining the media type used to  cable the network The networking topology impacts the cost of cabling the network.
