Question

Ensuring the uninterrupted flow of information' describes which key communications and information systems principle?

A. Security
B. Reliability, Scalability, and Portability
C. Resilience and Redundancy
D. Interoperability

Answer 1

C. Resilience and Redundancy

Step-by-step explanation:

Robust systems are characterized by having the ability to maintain their essential performance conditions despite receiving disturbances or noise. Robustness is the ability of a system to absorb stress and continue functioning, particularly when the system is subjected to unpredictable variations in its scope of performance.

The redundancy, consisting of the duplication of the critical components of a system, is developed with the purpose of granting robustness to the systems, so that in the event of the failure of a component that could jeopardize the main task or objective of the system, there is an alternative capable of replacing the system that suffers from a failure.

Robustness or resilience is characterized by two important aspects, the first is resistance to change or flexibility that is expressed as the ability of a system to resist a disturbance without undergoing irreversible change and the second is the ability of a system to recover.

Answer 2

Answer: C) Resilience and Redundancy

Explanation:

• According to the principle of communication and information system , redundancy is the factor that maintains the continuous flow of message or data even when failure is experienced in network by adding alternate or extra component in infrastructure for support.
• Resilience is the factors that helps network to persist even in the state of faults by keeping the main function working and recovering the fault to maintain the flow of data.
• Other options are incorrect because security is protection of data. Reliability factor means dependency , scalibility is changing scale of network and portability is changing position of components. Interoperability is exchanging information with devices and making use of it.
• Thus, the correct option is option(C).
