Describe a hybrid network.
What will be an ideal response?
A hybrid network combines the components of two or more network topologies. Two star networks are connected (with three additional nodes) via a bus. This used to be a common way to implement Ethernet, with coax running between classrooms or laboratories and hubs in each room to form small subnetworks. Putting together a hybrid network takes careful planning, for there are various rules that dictate how the individual components may be connected and used. For example, when connecting Ethernet segments, a maximum of four repeaters may be used with five segments. Furthermore, if a 4-Mbps token-ring network is interfaced with a 10-Mbps Ethernet network, there are performance issues that must also be taken into consideration (because any Ethernet traffic is slowed down to 4Mbps on the token-ring side). In addition, the overall organization of the hybrid network, from a logical viewpoint, must be planned out as well.
