Which term best describes the integrated set of industrial control components used to monitor and control processes, such as SCADA, RTU, PLC, and DCS?

• A. OT
• B. IIoT
• C. ICS
• D. CPS

Answer: (C)

Industrial control system (ICS) is the best description. It refers to the integrated collection of control hardware, software, and networks that monitor and regulate industrial processes, and it explicitly includes components like SCADA, RTU, PLC, and DCS as the core building blocks of that control environment. These elements work together to perform supervisory control, data acquisition, automation, and process regulation, forming the actual control layer of an industrial operation. Other terms exist in related spaces—OT describes the broader operations technology domain, IIoT focuses on internet-connected industrial devices and data exchange, and CPS is a broader notion of computing interacting with physical processes—but when naming the system that directly implements and oversees control of industrial processes, ICS is the precise fit.
