What Is Network Topology?
Network topology refers to how various nodes, devices, and connections on your network are physically or logically arranged in relation to each other. Think of your network as a city, and the topology as the road map. Just as there are many ways to arrange and maintain a city—such as making sure the avenues and boulevards can facilitate passage between the parts of town getting the most traffic—there are several ways to arrange a network. Each has advantages and disadvantages and depending on the needs of your company, certain arrangements can give you a greater degree of connectivity and security.
Network topology is also the arrangement of the elements of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks.
There are two approaches to network topology: physical and logical. Physical network topology, as the name suggests, refers to the physical connections and interconnections between nodes and the network—the wires, cables, and so forth. Logical network topology is a little more abstract and strategic, referring to the conceptual understanding of how and why the network is arranged the way it is, and how data moves through it.
What are the types of network topology
In computer networks, these are the types of network topologies, they are: Physical Topology: A physical topology describes the way in which the computers or nodes are connected with each other in a computer network. … Logical Topology: A logical topology describes the way, data flow from one computer to another
Other types of topologies in computer networks:
- Mesh Topology.
- Star Topology.
- Bus Topology.
- Ring Topology.
- Hybrid Topology
ADVANTAGES OF NETWORK TOPOLOGY
What are the advantages of network topology?Due to its centralized nature, the topology offers simplicity of operation. It also achieves isolation of each device in the network. Adding or removing network nodes is easy, and can be done without affecting the entire network. Due to the centralized nature, it is easy to detect faults in the network devices.
