Which statement correctly describes the relation between a device and a measuring component?
Correct Answer: D
A device is a physical or logical entity that can measure, control, or monitor something1. A measuring component is a single point for which data will be received and stored in the system2. A device can have one or more measuring components, or none at all2. Measuring components can be classified into two primary classes: scalar and interval2. Scalar measuring components are measured at unpredictable intervals, such as once a month2. Interval measuring components are measured at predictable intervals, such as every 15 minutes, every 30 minutes, every hour, etc2. A device can have any combination of interval and/or scalar measuring components, depending on the device type, device configuration, and measuring component type23. Therefore, the correct answer is D. A device can have any combination of interval and/or scalar measuring components. References:
