Show adapted from. www.newboston.org. The purpose of a network is to share data. Local Area Networks (LANs) are restricted to rooms, buildings and smaller geographical areas. LANs are often prohibited from outside (Internet) access. For example personal. 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. . Lecture9. Computer skills2. 2018-2019.
