Dragonfly Topology Description. The characteristics of a network depend upon the type of topology selected for designing that network. There are five basic network topologies. :-. 1) Star Topology. 2) Ring Topology. 3) Bus Topology. Topology of a network has great effect on the performance and network troubleshooting of a particular network.. . Topology. is a network specification that determines the network’s . overall layout . When working with a network. What is Physical Topology?????. The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations. .
