BUS TOPOLOGY
Network Topology and TypesNetwork topology has been one of the most researched topic in today’s world with the increasedimportance of network. The topology of the network is an arrangement of network that is formedin a communication network. The topology of network is an arrangement or the formation ofvarious types of networks of telecommunication. The topology of the communication alsoincludes command and control of radio networks, computer networks and industrial fieldbuses.The topology of the network is the structural form of the network presented in a topological wayboth physically or logically. Various types of communication devices are put together with thehelp of nodes that are bounded with the help of lines and links. Physical topology is one type of structure that is seen among the networks where variouscomponents of the networks are placed such as device location and installation of cable. On theother hand, it is seen that the logical topology helps in representing the way data flows inbetween networks. However, the nodes, physical interconnections, rate of transmission andsignals may different from one network to another. However, the topology of these nodes,physical interconnections and others are identical in nature. One of the example of networktopologies are seen in the local area network that is LAN. It is seen that in a LAN there are nodesthat has physical links with the devices in other network. These links are mapped graphically in ageometric shape. This shape of the links can be used to describe the physical topology of thenetwork. Similar format and process is followed in other types of network topology. LAN showsvarious types of physical topologies over the time such as ring, bus, mesh and star. Physical Topologies
There are various types of topologies that map the series of network, especially LAN design suchas start topology, bus topology, ring topology and mesh topology. These the four types ofphysical topologies seen in the network. Star topology This is the first types of topology that is formed by physical link in LAN in which all computersare seen to be connected under one hub or switch. The hub and the switch that is connectedusually helps in disbursing the flow of data within the network this is the most common type oftopology that is seen in the network and it follows the Ethernet standard. The start topology isseen in most of the LAN and is of good standard. Bus topologyThis is yet another types of topology in which the arrangement of various devices and computersare seen that are connected in a single linear cable form and is called the trunk of networks. Thetrunk that is formed in this type of topology are referred to as the backbone of the segment andeach of the trunk is seen to be discharged over the time. The discharge that is happening helps inpreventing the signal to rebounding back to the cable. This is yet another type of topology that isdeveloped in a network and is considered the backbone or the main part. Ring topology Ring topology is a type of topology in which the devices are seen to be connected to a closedloop cable. This type of topology does not have any kind of terminating ends and thus everysystem is connected to each other. Thus it is seen that when one system in the topology crashesthen the entire network crashes down. In this type of topology each functions of the computerhelps in charging the signal before sending it to other stations.
Mesh topologyThis is yet another type of physical topology in which the topology help sin linking nodes withconnections. These connections helps in seeing that multiple paths between some of the points inthe networks are available. The topology of this network is in a fully meshed form, however,there are two types of meshed network such as fully meshed and partially meshed. The fullymeshed topology is formed when all the nodes in the network are directly connected to eachother without any particular format. Further, the partially meshed topology is formed when onlysome of the nodes are connected to each other. The resilience of the meshing to create multiplepaths when faced under failure, however, it tends to increase cost. One of the example of meshnetwork is internet in which it is a mesh topology where all nodes are connected to each other ina mesh form. Logical TopologiesThe above showed the types of physical topologies that are seen in the entire theory of networktopology. A logical topology is also seen in the network topology that helps in explaining therelationship between nodes and logical connections that exists. The logical connection of thenodes differs from the physical path that the nodes are passing by. All types of physical topologyis seen to have a logical connection within itself that explains the way in which the topology hasbeen formed. What is Bus Topology?Bus topology is one kind of physical topology that also has some kind of logical connection intheir nodes. A bus topology is seen to consist devices that are connected through single cable.This single cable is then shared among all the connected devices so that they all can receive the
