In this type of network topology, all the nodes of a network are connected to a common transmission medium having two endpoints. All the data that travels over the network is transmitted through a common transmission medium known as the bus or the backbone of the network.
When the transmission medium has exactly two endpoints, the network topology is known by the name, 'linear bus topology'. In case the transmission medium, also called the network backbone, has more than two endpoints, the network is said to have a distributed bus topology.
Bus topology is easy to handle and implement and is best suited for small networks. But the downside of this topology is that the limited cable length limits the number of stations, thus limiting the performance to a less number of nodes.

•advantage of network topology
1.The bus is simple, reliable in small network, easy to use and understand
2.Requires the least amount of cable to connect the computers and less expensive
3. Easy to extend the bus
•Disadvantage of network topology
1.Heavy network traffic can slow a bus considerably
2.Each barrel connector weakens the electrical signal
3. Difficult to troubleshoot a bus
