This topology is also mostly used in small areas like LAN's (Local Area Network) and it provides security and speed. In Star topology all hosts are directly connected to a centralized device that can be a hub or switch, Here the relation between the node and the central device is point-to-point. Any host requesting for service or providing service, first contact the switch or hub for communication. Higher chances of congestion and traffic on the bus because of its single source of communication.Messages are reaching all to nodes that lead to security concerns.If the bus fails, the whole network will fail.Efficiency will reduce when you expand the network.
In the below picture you can see both ends of the cable have a line terminator. However, the failure of the common communication line can affect all other devices that result in to stop working of the network. Here the failure of one device does not affect other devices. Its working is simple so when a sender sends a message, all other computers that are connected to the network can hear it, but only the receiver accepts that message and others rejects it. In a Bus topology, a common bus or medium is used for communication in the network i.e, It uses a single cable that work like a backbone of the entire network, but it can link more than two hosts. In simple the receiving end of one node (Destination) is connected to the sending end of other host. Point-to-point networks are a very basic and simple type of networks containing exactly two hosts that can be computer, switches, routers, servers which directly connected end to end using a single piece of cable. Here we will see different types of physical topologies, with their benefits, and drawbacks. Let's first concentrate on physical topologies. Virtual and Cloud resources are a good example of Logical network topologyĮffective network management and monitoring require a solid understanding of the physical and logical topology of a network to confirms that the network is efficient and healthy. The logical network topology tells about how the network is setup, lt defines the routng path, from where data flow from one computer to another. you can say that it is the physical layout of devices, computers, and cables in the network. and the arrangement of networking devices.
The physical network topology deals with the actual connections like wires, cables, etc. Basically, there are two types of topologies in a computer network which are discussed below: Physical Network Topology Now we clear with all basic terms so let's see what are the types of Network Topology. Better performance, in turn, helps to minimize costs for maintenance and operations with a properly managed network topology. Choosing the right topology makes it easier to locate faults, fixes problems, and share resources across networks.Ī business can enhance the performance of its data transfer. Making a network topology before implementing a network helps network administrators to maximize performance while completing business needs. Why is Network Topology Important?Īs we know now what is a network topology we also got almost an idea of why is it important? But still, there are more points that you can see below. we need to build a map and that map is called network topology. Let's understand with an example, whenever we build a house then building a map or blueprint of that house is the initial step, same when we build a network for organization, home, building etc. The network topology defines how the different nodes, devices, and connections in the network are physically or logically organized with each other. Network Topology represents how devices are connecting and communicating with each other using connected links. In computer networks, topology is used to describes how a network is physically connected and the logical flow of data in the network. Topology is built with two Greek words topo and logy, where topo is for ' place' and logy is for ' study'. So let's get started with a basic definition of topology
