Ensuring the uninterrupted flow of information' describes Redundancy and Resilience.
Redundancy can be explained as the arrangement of duplicate devices in critical areas in case the primary device fails.
Resilience is, by definition, the ability to recover and restore to normal functioning after a failure.
In order for resilience to exist, there has to be redundant systems. The use of these two principles is what ensures the uninterrupted flow of information.
