A bus network topology is a network architecture in which a set of clients are connected via a shared communications line, called a bus. There are several common instances of the bus architecture, including one in the motherboard of most computers, and those in some versions of Ethernet networks. Bus networks are the simplest way to connect multiple clients, but often have problems when two clients want to transmit at the same time on the same bus
A true bus network is passive – the computers on the bus simply listen for a signal; they are not responsible for moving the signal along. However, many active architectures can also be described as a "bus", as they provide the same logical functions as a passive bus; for example, switched Ethernet can still be regarded as a logical bus network, if not a physical one. Indeed, the hardware may be abstracted away completely in the case of a software bus.
The bus topology makes the addition of new devices straightforward. The term used to describe clients is station or workstation in this type of network. Bus network topology uses a broadcast channel which means that all attached stations can hear every transmission and all stations have equal priority in using the network to transmit data.( http://en.wikipedia.org/wiki/Network) The advantages of bus topology are
* Easy to implement and extend
* Requires less cable length than a star topology
* Well suited for temporary or small networks not requiring high speeds(quick setup)
* Cheaper than other topologies
Some of the Disadvantages
* Limited cable length and number of stations.
* If there is a problem with the cable, the entire network goes down.
* Maintenance costs may be higher in the long run.
* Performance degrades as additional computers are added or on heavy traffic.
* Proper termination is required (loop must be in closed path).
*...
