The Advantages And Disadvantages Of The Linear Bus Topology

The Linear Bus Topology has all of the nodes connected to on single connection medium which has two end points. This type of set-up has multiple advantages, such as it is easy to set-up, it requires the least amount of cables, low cost, and it is used for small LAN’s. The distributed Bus Topology is a more complicated version of a Bus network. Unlike the Linear Bus, the Distributed Bus has more than two end points. This setup starts out looking like the linear bus with a main trunk cable that is referred to as the root or head end. Multiple network nodes can be connected to this main trunk line. The trunk cable branches off by a connector on the main trunk. This type of Bus topology has more disadvantage than the linear bus topology. The intersecting…show more content…
When a system transmits data, it sends the data to the central device. The central device, which was a hub when the star network first came out, then broadcasts the transmission out to all of the connected devices. This set-up reduces the chance of a network failure because if one node goes down, the network will still be up and operational. However, if the central device goes down, then the entire network will go down. The use of hubs has been removed from modern day networks because they are essentially dumb devices. Since the hub will forward information to every device that is connected to it, the chances of a collision occurring is pretty high. A switch will learn the MAC address of the systems that is connected to it. Once a switch has learned the MAC addresses of the systems that are connected, it will send information that is intended for that system only to the port that the system is connected to. This smart filtering that the switch performs drastically helps to eliminate collisions on the star network. The star topology is the most popular choice of networks due the easiness of setup and the lower costs of equipment. The star network can use twisted pair, fiber, or coaxial cable as its network
