1. Bus topology

Commonly referred to as a linear bus, all the devices on a bus topology are connected by
one single cable. The main problem faced in implementing this topology is the fact that only one
communication channel exists to serve the entire network. As a result, if this channel fails, the
whole network will go out of operation,

Advantages
1. It is easy to handle and implement.
2. It is best suited for small networks.
3. Easy to connect a computer or peripheral to a linear bus
4. Requires less cable length than mesh or star topologies.
5. It is cheaper than any other topologies
Disadvantages
1. The cable length is limited. This limits the number of stations that can be connected.
2. This network topology can perform well only for a limited number of nodes
3. If the network cable breaks, the entire network will be down.
4. Terminators are required at both ends of the backbone cable.
5. Difficult to identify the problem if the entire network shuts down.
6. Not meant to be used as a stand-alone solution in a large building.
7. Include difficult reconnection and fault isolation.
8. The managing cost of network is too high.
9. Addition of new devices requires modification or replacement of the backbone.
