It is the simplest and most common method of connecting computers in the network. It consists of a single cable (backbone, trunck - segment, trunk, column), which connects all hosts on a single line.Computers in a network with bus topology data communication addressed to a particular computer and transfer them cable form of electronic signals.
A signal from a computer spreads throughout the column and reach all computers almost instantly. Although electronic signals are sent to all connected computers, computer information is accepted only who is sent signal (whose address is encoded in the signal). At one point, one computer can send messages. For this reason, network performance depends on the number of computers attached to the bus. With how many computers are connected with so many of them are expected to place data on the bus, and so the network will be slower.
The bus topology is passive. Computers connected to a bus receives the data being sent over the network. If a computer fails, it does not affect the rest of the network. Because the data or electronic signals are transmitted through the entire cable network they at one end to another.
If the signal and were allowed to move without interruption, he would continue to be reflected back and forth along the cable, preventing other computers to transmit signals. For this reason, the signal should stop after arriving at the destination.
To stop the reflection signal at each end of the cable is placed a component called terminator, which serves to absorb free signals.
