Types of Network TopologyThe arrangement of a network that comprises nodes and connecting lines via sender and receiver is referred to as network topology. The various network topologies are: Show a) Mesh Topology :In a mesh topology, every device is connected to another device via a particular channel. Figure 1: Every device is connected with another via dedicated channels. These channels are known as links.

Problems with this topology :
b) Star Topology :In star topology, all the devices are connected to a single hub through a cable. This hub is the central node and all other nodes are connected to the central node. The hub can be passive in nature i.e., not an intelligent hub such as broadcasting devices, at the same time the hub can be intelligent known as an active hub. Active hubs have repeaters in them. Figure 2: A star topology having four systems connected to a single point of connection i.e. hub. a Advantages of this topology :

c) Bus Topology :Bus topology is a network type in which every computer and network device is connected to a single cable. It transmits the data from one end to another in a single direction. No bi-directional feature is in bus topology.It is a multi-point connection and a non-robust topology because if the backbone fails the topology crashes. Figure 3: A bus topology with shared backbone cable. The nodes are connected to the channel via drop lines. Advantages of this topology :
Problems with this topology :
d) Ring Topology :In this topology, it forms a ring connecting devices with its exactly two neighboring devices. A number of repeaters are used for Ring topology with a large number of nodes, because if someone wants to send some data to the last node in the ring topology with 100 nodes, then the data will have to pass through 99 nodes to reach the 100th node. Hence to prevent data loss repeaters are used in the network. The transmission is unidirectional, but it can be made bidirectional by having 2 connections between each Network Node, it is calledDual Ring Topology. Figure 4: A ring topology comprises 4 stations connected with each forming a ring. The following operations take place in ring topology are :

e) Tree Topology :This topology is the variation of Star topology. This topology has a hierarchical flow of data. Figure 5: In this, the various secondary hubs are connected to the central hub which contains the repeater. In this data flow from top to bottom i.e. from the central hub to secondary and then to the devices or from bottom to top i.e. devices to the secondary hub and then to the central hub.It is a multi-point connection and a non-robust topology because if the backbone fails the topology crashes.
