Definitions of Network Topology
Network topology describes the physical and logical relationship of nodes in a network, the schematic arrangement of the links and nodes, or some hybrid combination thereof. Network topology is the schematic description of the arrangement of the physical and logical elements of a communication network.
Network topology refers to the manner in which the links and nodes of a network are arranged to relate to each other. Topologies are categorized as either physical network topology, which is the physical signal transmission medium, or logical network topology, which refers to the manner in which data travels through the network between devices, independent of physical connection of the devices. Logical network topology examples include twisted pair Ethernet, which is categorized as a logical bus topology, and token ring, which is categorized as a logical ring topology.
Physical network topology examples include star, mesh, tree, ring, point-to-point, circular, hybrid, and bus topology networks, each consisting of different configurations of nodes and links. The ideal network topology depends on each business’s size, scale, goals, and budget. A network topology diagram helps visualize the communicating devices, which are modeled as nodes, and the connections between the devices, which are modeled as links between the nodes.
Topology defines the structure of the network of how all the components are interconnected to each other. There are two types of topology: physical and logical topology.
Physical Network Topology:-
Physical topology is the geometric representation of all the nodes in a network.
The physical network topology refers to the actual connections (wires, cables, etc.) of how the network is arranged. Setup, maintenance, and provisioning tasks require insight into the physical network.
Logical Network Topology:-
The logical network topology is a higher-level idea of how the network is set up, including which nodes connect to each other and in which ways, as well as how data is transmitted through the network. Logical network topology includes any virtual and cloud resources.
Importance of Network Topologies
The layout of a network has a direct impact on network functionality. Selecting the right topology can improve performance and data efficiency, optimize allocation of resources, and reduce operational costs.
Software-created network topology diagrams are important references for diagnosing network connectivity problems, investigating network slowdowns, and generally troubleshooting issues.
One of the primary uses of network topology is to define the configuration of various telecommunication networks, including computer networks, command and control radio networks, and industrial fieldbuses.
Why Network Topology Important?
The layout of your network is important for several reasons. Above all, it plays an essential role in how and how well your network functions. Choosing the right topology for your company’s operational model can increase performance while making it easier to locate faults, troubleshoot errors, and more effectively allocate resources across the network to ensure optimal network health.
A streamlined and properly managed network topology can increase energy and data efficiency, which can in turn help to reduce operational and maintenance costs.
The way a network is arranged can make or break network functionality, connectivity, and protection from downtime. The question of, “What is network topology?” can be answered with an explanation of the two categories in the network topology.
