This transition from 0 to 1 signals transmission of the bit to the receiver of the network. The use of appropriate wiring can subdue this problem. The coaxial cable uses an outer layer that protects the signals from outside interference and prevents radiation. Modern physical topology of a network moves rapidly in the direction of fiber-optic cabling. The usage of fiber-optic cables greatly improves the security of a system.
Coaxial cable allows tapping into it because it picks up and radiates the signals.
If the light is intercepted before reaching the connectors, the link fails indicating a brake in the system. The star topology is one of the most common ways to connect the network cables between the computers and the central wiring hub. Computers on the system are wired to the hubs which are connected to the central wiring hub located in the wiring closet.
