However, in a bus system, all networking devices will see computer 1’s data traffic to the printer, and the other devices must wait for pauses in transmission or until it is complete before they can initiate their own transmission. If more than one computer’s data is placed on the network at the same time, the data will be corrupted and must be retransmitted. This means that the use of a shared coaxial cable in a bus topology prevents data transmission from being very bandwidth-efficient. This is one reason, but not the only reason, why bus topologies are seldom used in modern computer networks.
