Network Topology When it comes to computer networks, there are many different methods in which separate components may be linked to one another. The Network Topology is the manner in which the structure is defined, as well as the manner in which the components are linked to one another. Types of Network Topology : Network topology is the layout of a network that includes nodes and connecting lines via sender and receiver. This arrangement is referred to as the network topology framework. The various network topologies are: 1. Point to Point Topology The Point-to-Point Method Topology is a sort of topology that focuses on the functioning of both the sender and the receiver. This is the most basic kind of communication that may take place between two nodes, with one of the nodes acting as the transmitter and the other as the receiver. There is a high bandwidth provided by point-to-point. 2. Mesh Topology A mesh topology is a network architecture in which every device is linked to another device over a specific channel. The protocols that are used in Mesh Topology include and are not limited to Ad Hoc Configuration Protocols (AHCP), Dynamic Host Configuration Protocol (DHCP), and others. Advantages of Mesh Topology : Drawbacks of Mesh Topology : The internet backbone is a typical example of a mesh architecture. In this configuration, different internet service providers are linked to each other via dedicated channels. Additionally, this topology is used in the communication systems of the military as well as the navigation systems of airplanes. 3. Star Topology The Star Topology configuration involves all of the devices being linked to a single hub by means of a wire. All other nodes are linked to this hub, which serves as the central node. This hub is the connected node. It is possible for the hub to be passive in nature, which means that it is not an intelligent hub like broadcasting devices. On the other hand, the hub may also be intelligent, which is referred to as an active hub. It is common for active hubs to have repeaters. When it comes to connecting the computers, either coaxial cables or RJ-45 cables are used. A wide variety of well-known Ethernet local area network protocols, such as CD (Collision Detection), CSMA (Carrier Sense Multiple Access), and others, are used in Star Topology. Advantages of Star Topology : Drawbacks of Star Topology : 4. Bus Topology Every computer and other network device is linked to a single cable in a bus topology network, which is a sort of network configuration. It may go in both directions. Due to the fact that the topology will fail in the event that the backbone fails, it is a multi-point connection and that it is not a resilient topology. There are several different MAC (Media Access Control) protocols that are followed by LAN ethernet connections in Bus Topology. These protocols include TDMA, Pure Aloha, CDMA, Slotted Aloha, and others. Advantages of Bus Topology : Drawbacks of Bus Topology : 5. Ring Topology In a Ring Topology, it creates a ring that connects devices with precisely two connected devices that are next to one other. In a Ring topology with a high number of nodes, a lot of repeaters are used. This is due to the fact that if someone wishes to transmit some data to the last node in the ring topology with 100 nodes, then the data will have to go via 99 nodes in order to get at the 100th node. Therefore, repeaters are used in the network in order to avoid the loss of data. The data travels in just one way, which is referred to as unidirectional. However, it is possible to have the data flow in both directions by establishing two connections between each Network Node. This configuration is known as Dual Ring Topology. For the purpose of data transmission, the workstations in the Ring Topology make use of the Token Ring Passing protocol. Advantages of Ring Topology : Drawbacks of Ring Topology : 6. Tree Topology This topology is a variant of the Star topology for the Star topology. The data flows in a hierarchical fashion across this structure. DHCP and SAC, which stands for “Standard Automatic Configuration,” are examples of protocols that are used in Tree Topology. Advantages of Tree Topology : Drawbacks of Tree Topology : 7. Hybrid Topology This particular topological technology is the culmination of all of the other kinds of topologies that we have discussed in the previous section. It is possible to employ hybrid topology when the nodes are allowed to assume whatever shape they want. This indicates that they may be unique topologies, such as the Ring or Star topology, or they can be a blend of the numerous sorts of topologies that were discussed before. Additionally, the protocol that was explained previously is used by each and every separate topology.
