Final answer:
The protection that includes redundancy in devices and circuits to ensure business continuity is based on the principle of redundancy. It involves having backups for critical components, such as hardware and data, to prevent service disruptions due to failures, which is a key part of business continuity planning.
Step-by-step explanation:
The question refers to the protections employed within businesses to ensure continuity in case of various failures. One such protection is based on the principle of redundancy, which specifically includes having duplicate devices and circuits to prevent service disruptions due to hardware failure.
By having redundant components, businesses can ensure that if one device or circuit fails, another can take over immediately to maintain operations. This concept is crucial in areas where uninterrupted service is critical, such as in data centers, health care systems, financial institutions, and online service providers.
Business continuity planning is another important aspect within this context. It involves strategies that ensure critical business functions can continue during and after a disaster. Redundant systems are a key component of such plans, implying that multiple backups are in place for both hardware and data. This could mean having multiple power sources, network paths, servers, or whole data centers that can take over in case the primary system fails.
While the details provided in the available references touch upon electrical safety systems, such as circuit breakers and transformers, to prevent thermal and shock hazards, these are not directly related to redundancy for business continuity purposes. Instead, they are part of the overall safety and infrastructure design to prevent electrical accidents. Nonetheless, the concept of redundancy could apply to electrical safety where multiple safeguards might be in place to prevent overloading or electrical faults.
