Answer:
The connecting cables
Step-by-step explanation:
A network is a collection of end systems and other nodes in which links are connected so as to enable communication between the end systems.
The cable is a very vital element of a network, most especially in wired networks. The cable always has an outer shield that serves the purposes of protecting the cable itself and the users. If the covering of this cable deteriorates, it can cause a bridge or a short circuit in the network.
