Rationale: This should be straightforward if you think through what the potential threats involve.Lightning strike or electrical storms are a key cause of power supply failures and surges which may effect computer functions. Fire and accidental damage are also physical threats to data and equipment. Hacking is a non-physical threat involving unauthorised access to data (possibly resulting in data theft or destruction).
