Network Topology 1 Star

Bus was a very commonly used distributional topology in the past. Using the bus topology, computers are connected to only one network in a straight line, using one wire to connect to the main bus line, and have no other connections with each other. A typical example is a coaxial cable. Some advantages possible are a low cost and the simplicity of installation; however, low reliability brings nothing to these advantages. An example of this disadvantage would be the result of one defective cable stopping the work of the entire network. From the logical point of view, a bus topology enables every networking device to see all signals from all other devices. This can be an advantage, if the administrator wants all the information to go to every device, as in broadcasting.
