Bus network

This article is about a type of computer network. For networks of municipal bus routes, see Public transport bus service.
Topology of a bus network

A bus network is a network topology in which nodes are directly connected to a common linear (or branched) half-duplex link called a bus.[1][2]

Function

A host on a bus network is called a Station or workstation. In a bus network, every station receives all network traffic, and the traffic generated by each station has equal transmission priority.[3] A bus network forms a single network segment and collision domain. In order for nodes to transmit on the same bus simultaneously, they use a media access control technology such as carrier sense multiple access (CSMA) or a bus master.

If any link or segment of the bus is severed, all network transmission ceases due to signal bounce caused by the lack of a terminating resistor.
