Topology of a bus network

A bus network is a network topology in which nodes are connected in a daisy chain by a linear sequence of buses.

How it works[edit]

The bus is the data link in a bus network. The bus can only transmit data in one direction, and if any network segment is severed, all network transmission ceases.

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.[1] Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously, they use a media access control technology such as carrier sense multiple access (CSMA) or a bus master.

Advantages and disadvantages[edit]
