116) Compare and contrast star network, ring network, bus network, and mesh network
topologies.
A bus network is in the shape of an open-ended line; as a result, it is the easiest network to
extend and has the simplest wiring layout. This topology enables all network nodes to receive the
same message through the network cable at the same time. However, it is difficult to diagnose
and isolate network faults. Bus networks use variants of CSMA for media access control.
A mesh network consists of computers and other devices that are either fully or partially
connected to each other. In a full mesh design, every computer and device is connected to every
other computer and device. In a partial mesh design, many but not all computers and devices are
connected. Like a ring network, mesh networks provide relatively short routes from one node to
another. Mesh networks also provide many possible routes through the network-a design that
prevents one circuit or computer from becoming overloaded when traffic is heavy. Given these
benefits, most WANs, including the Internet, use a partial mesh design.
