Which of the following lists operating systems specifically designed for ultra-low-power, memory-constrained microcontrollers in IoT networks?
Contiki-NG, FreeRTOS, and similar lightweight RTOSs are designed for constrained IoT devices with limited memory, processing power, and energy.
Which of the following describes a 'Smart Environment' in IoT?
Smart environments (e.g., smart homes, smart cities) utilize IoT nodes to capture real-time ambient data and execute automated control actions.
In IoT hardware architecture, what is the role of an Analog-to-Digital Converter (ADC)?
ADC converts continuous physical measurements (voltage, temperature, pressure) from analog sensors into digital binary data processed by microcontrollers.
Which micro-controller platform is widely used in IoT rapid prototyping due to built-in Wi-Fi and Bluetooth capabilities at low cost?
ESP32 and ESP8266 by Espressif Systems are ultra-low-cost, feature-rich microcontrollers with integrated Wi-Fi and Bluetooth stacks widely used in IoT.
What is 'Lightweight Cryptography' (LWC) in the context of IoT information security?
NIST Lightweight Cryptography (LWC) standards (such as ASCON, PRESENT) provide strong confidentiality/integrity while minimizing gate count, latency, and battery power.
