Which capability allows users to access, control, and manage IoT-enabled operations?

• A. IoT
• B. Bigdata
• C. Network
• D. Communication

Answer: (A)

Access to, control of, and management of IoT-enabled operations are provided by the IoT system as a whole. IoT brings together devices, sensors, actuators, a communication backbone, and software interfaces (dashboards, apps, automation rules) that let you observe device status, change settings, and automate actions across many devices from a single place. For example, you can monitor temperatures from sensors, adjust a thermostat, and trigger an HVAC system automatically when thresholds are met. Big Data focuses on analyzing the large volumes of data generated by these devices, not on directly controlling them. The network and communication layers enable data exchange, but the capability to access and manage devices comes from the IoT platform that unifies these components into usable control interfaces.
