What is bus network?


  • .Easy to connect a computer or peripheral to a linear bus
  • .Requires less cable length than a star topology
  • .It works well for small networks.

Bus Network disadvantages

  • .Entire network shuts down if there is a break in the main cable
  • .Terminators are required at both ends of the backbone cable
  • .Difficult to identify the problem if the entire network shuts down
  • .Not meant to be used as a stand-alone solution in a large building
  • .It is slow when more devices are added into the network
  • .If a main cable is damaged then network will fail or be split into two networks


The bus is the data link in a bus network. The bus can only transmit data in one direction, and if any network segement 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 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 or a bus master
