Which term describes a network of appliances and personal devices equipped with sensors, software, and network connectivity?

• A. Embedded Systems
• B. BACnet
• C. Microcontrollers
• D. SoC

Answer: (A)

The idea being tested is how devices with sensors, software, and network links come together into a connected environment. Each appliance or personal device contains an embedded system—a dedicated computer that runs its software, processes sensor data, and communicates over a network. When many of these embedded systems are linked, they form a network of smart devices that can share information and coordinate actions. This description matches the concept of embedded systems forming a networked ecosystem of everyday devices.

BACnet is a specialized protocol used for building automation; it’s about interoperability in facilities, not the general notion of a connected device network. Microcontrollers are the small processors inside devices—they’re components of embedded systems, not the overall network concept. SoC, or system on a chip, describes an integrated hardware package, not the network of many devices.
