Answer:
The answer is "Backbone".
Step-by-step explanation:
The backbone cables crossover connectors, intermediate and main interconnections, electrical inductions and bug fix cables, and jumping wires are used for cross-connecting the backbone with the backbone. Cabling between buildings also involves backbone cables. This interconnection of rooms, entry facilities, equipment rooms, or buildings, that's why its entire system/network would then fail if the backbone cord harms it.
