This figure illustrates the bus topology.In a bus topology,a cable proceeds from one computer to the next like a bus line going through a city.The main cable segment must end with a terminator that absorbs the signal when it reaches the end of the line or wire.If there is no terminator,the electrical signal representing the data bounces back at the end of the wire,causing errors in the network.
