Advantages And Disadvantages Of Bus Topology

The bus topology is a type of Local Area Network topology that connects all nodes to a single point. The cable that connects the node is called the backbone. In a bus network all the servers, workstations and printer are joined together to a cable. At the end of h cable there us a terminator that stops signal reflecting down the bus. The terminator absorbs the electrical energy as well as prevents the reflection too. Usually the Ethernet cable is used for the bus topology. To deliver the information to the last node the signals have to be passed all over the cable. But if the cable is damaged the connection of all the computers will be lost and it will work not work. So it is better to use the co axial cable in order to make to increase the strength of the network depend on the computer. When the bus topology has both end point it is known as linear topology. In bus topology the data transfers in only one direction. The node that transfers information is called the host. The computer connected with network takes network traffic. Moreover each node equally transfers the data and the node uses bus technology for transferring the information. rnIn bus topology all the nodes like work stations, printers and servers are connected to the linear cable. The main function if the terminator is to absorb the signal when the signal reaches to the end in order to stop the reflection of the signals. rnFurther when the signal delivers by a computer it flows all through the cable and. After that it goes back to that computer when it reaches to the end of the cable by bouncing back. This phenomenon is called the signal bounce. The signal bounce often creates problem in the computer network because if another signal is delivered by another computer at that time the collision occur. Moreover the collision in the bus topology lower the speed and causes delay in the work too. Types of topology Generally the network topology is a physical layout combining the computer, printer, workstation and the server. There are number of network topologies and a network can be built by using the multiple number of topologies. There are different kinds of topology like bus topology, star topology, ring topology, mesh topology and ring topology. The Advantages And Disadvantages Of Bus Topology Like all other topology the bus topology has both advantages and disadvantages too. The advantages of bus topology • Easy to install • Cost efficiency • Small cables are required for connectionrn• Easy to extend the network by the single cable • Can be connected in linear. • The repeater boosts the signal and transfers the signal to a long distance. The disadvantages are as follow: • Difficult to identify the problems if the entire network shutdown. • More work stations are connected so the speed becomes slow due to the collision of data. • If the main cables fail then the full system network will fail too. • Difficult to troubleshoot the bus due to cable break or loose. • Terminators are required at the both backbone of the cable. • Not good for using standalone solution. There are many kinds of topologies that connect multiple devices in different layouts .The bus topology connects all the work station and the server by simple and easy way. The bus topology is a good option of network topology to install easily. Bus topology helps to build the network connection among the computer, workstation, printer and other devices by a cable. The connection of bus topology is easier than other topologies.
