S stands for which term?

• A. Sensor
• B. System
• C. Status
• D. Subsystem

Answer: (B)

S stands for the entire collection of parts and processes that work together to achieve a purpose. In many diagrams and descriptions, the system is the broad entity that contains sensors, controllers, actuators, and other components. A sensor is just one device within the whole, not the whole grouping. Status describes a state or condition, not the overall object being labeled. A subsystem is a part of the larger system, whereas the question is asking for the term that represents the whole. So, System is the most natural and general meaning for S in this context.
