Describe the backbone structures that form the foundation for most LANs. Simple Physical Topologies. 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. Objectives.

CSC1202-2013 (c) Nouf AlJaffan. 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. .
