“A bus network topology is a network architecture in which a set of clients are connected via a shared communications line/cables” (Abu, 2013). There are several common instances of the bus architecture, including one in the motherboard of most computers. Bus networks may be the simplest way to connect multiple clients even though many may have problems. When two clients want to transmit at the same time on the same bus, this may cause some problems. Thus systems use bus networks normally some may have scheme for collision handling or collision avoidance for communication on the bus. Though this may be quite often in using Carrier Sense Multiple Access or the presence of a bus master’s who controls access to the shared bus resource.
“A ring network is a network topology in which each node connects exactly to two other nodes, forming a single continual pathway for each node - a ring” (Conjecture Corporation, 2003). In a ring network data travels from each node to the other node/s with each node handling every packet. A ring network provides only a pathway between any two nodes at one time. Ring networks may be disrupted by the failure of a link. A node failure or cable break will isolate every node attached …show more content…
The logical topologies are generally determined by network protocols as opposed to being determined by the physical layout of cables, wires, and network devices or by the flow of the electrical signals, although in many cases the paths that the electrical signals take between nodes may closely match the logical flow of data, hence the convention of using the terms logical topology and signal topology
