In a production environment, which arrangement of devices communicates to monitor and control operations without human input?

• A. IoT
• B. SCADA
• C. PLC
• D. M2M (Machine to Machine)

Answer: (D)

Autonomous device-to-device communication in an industrial setting is being tested here. Machine-to-Machine (M2M) refers to devices such as sensors, actuators, controllers, and other equipment exchanging data and signals directly with each other to monitor and control processes without requiring a human to intervene each time. This setup enables continuous, automatic operation, quick responses to changes, and coordinated action across the production line. Other options involve elements that either rely on human input or describe a narrower component of automation. IoT centers on connected devices and often cloud-based data processing and interfaces for human users, even though it can enable automation. SCADA systems provide supervisory control and data acquisition with operator interfaces, so human operators typically monitor or adjust as needed. A programmable logic controller handles automated control logic, but it’s usually a single device or a local controller rather than an arrangement of multiple devices communicating autonomously across a system. So the arrangement described—devices communicating to monitor and control operations without human input—fits machine-to-machine communication best.
