Bus networks use a common backbone to connect all devices. The backbone is a high capacity communications medium that joins networks and central network devices on the same floor in a building. A single cable, the backbone functions as a shared communication medium, that devices attach or tap into with an interface connector . A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message (7).
The main advantages of a bus network are:
- Easier to locate problem workstations
- depending on the backbone can provide very fast networks
The main disadvantage of bus networks are:
- issues with security as data is broadcasted across the network
- Single point of failure - if hub or backbone goes down
