Answer: B - Bus topology is a single cable running the entire length of the network. Nodes are attached to the network through drop points on this cable. Data communications transmit the length of the medium and each packet transmitted has the capability of being “looked at” by all nodes. Each node decides to accept or ignore the packet, depending upon the packet’s destination address. There are two types of bus topologies: linear and tree. The linear bus topology has a single cable with nodes attached. A tree topology has branches from the single cable and each branch can contain many nodes.
