PHYSICAL BUS TOPOlogy
- Physical Bus Topology -- it is when all nodes are connected to a single backbone.
- The backbone is a single cable that carries data packets to all nodes. Each node attaches and listens for data present on the backbone via a T connector or vampire connector.
- As the two ends of the backbone cable are not joined it is necessary to install terminations at each end.
- Terminators — prevent reflection of the data signal back down the cable.
- On electrical networks, terminators are resistors that completely stops the flow of electricity by converting it into heat.
- Today, it is used for high speed backbones and long distance connections within commercial and government WANS.
