![]() Easy to install and implement on small or large network.But the performance of the network can decrease if it is crowded. The number of devices depends on the number of ports the hub has. ![]() This network provides better security as the hub controls which node gets access to the data. In this topology, the number of links are equal to the number of devices. Depending on the network card in each devices, either a coaxial cable or a network cable with a RJ-45 connector is used to connect the nodes to the hub. The hub receives the data and transmits it to the receiver. In order to send data from one device to another, a node has to first contact the hub. It means the communication will be hampered if the hub is damaged. The hub controls the data transmission in this topology. It is the most popular topology and most commonly used for setting up a network. In this topology, the devices are connected to a central hub or switch forming a shape similar to a star. The number of nodes are limited to the length of the backbone.If the backbone fails then the entire network fails.It is difficult to identify the damaged node.Damage in one node doesn't influence the other nodes or the system.In this topology, the message from the host goes to every device on the network but only a specific receiver will be able to receive as the address will be added with the message. The device that transmits the data is called 'Host'. The number of links are same as the number of devices.Įach node has its own address so that data can be transmitted to a specific device. This backbone can be ethernet cable, coaxial cable, or a network card based on the type of the device. The connector that connects the drop line and the link is called 'Tap'. The device and the link are connected with separate cable and it is called 'Drop line'. If the backbone is damaged then every device connected on this network will lost connection. The single link through which the nodes are connected is called 'Backbone' and the devices communicate with this backbone. It is considered as the simplest type of topology and mostly used for the Local Area Network. It is also referred to as line topology or horizontal topology. Bus Topologyīus topology is named for the arrangment of the nodes or devices on a single link. These different formations of the devices can help the management to find out errors and resolve them easily. Topologies are used for ensuring efficient performance of the network which means better communication. These devices are called 'nodes' and they are connected through cables which are called 'links'. The topologies are named from the way the devices are connected to each other. Topology means the way different devices are arranged to create a network for telecommunication. In this article, we will discuss about the 6 different types of topologies that exist in a computer network. ![]()
