How does a subnetwork differ from the overall utility network?

A subnetwork is a focused part of the overall utility network that targets specific segments, such as a particular area or system component, rather than encompassing the entire utility system as a whole. This allows for more efficient management and analysis of subsections of the infrastructure. By isolating specific areas or functionalities, subnetworks can streamline processes, optimize resource allocation, and facilitate concentrated maintenance efforts.

The choice indicating that a subnetwork represents the entire utility system is inaccurate because a subnetwork only addresses a portion of that system. Similarly, identifying it as containing unrelated infrastructure mischaracterizes its purpose, which is to represent interconnected elements of a particular segment of the overall utility. The option regarding managing all historical data does not capture the essence of what a subnetwork does; while historical data can be relevant, it does not define the functional aspect of subnetworks within the larger utility framework.
