Data analytics tools in IoT are essential for analyzing large datasets generated by IoT devices. These tools provide stakeholders with insights into trends, patterns, and anomalies, which can be valuable for decision-making and optimization.
Which of the following is a real-time operating system commonly used in IoT devices?
- FreeRTOS
- MacOS
- Ubuntu
- Windows 10
FreeRTOS is a real-time operating system (RTOS) that is commonly used in IoT devices. RTOS is essential for managing tasks with strict timing requirements in IoT applications. Windows 10, Ubuntu, and MacOS are general-purpose operating systems not designed for real-time tasks.
Which framework is known for providing a unified method for connecting and managing IoT devices?
- AllJoyn
- CoAP
- IoTivity
- MQTT
MQTT (Message Queuing Telemetry Transport) is a widely used framework for connecting and managing IoT devices. It provides a lightweight, efficient communication protocol for IoT. CoAP, IoTivity, and AllJoyn are also IoT protocols and frameworks.
A compromised bootloader in an IoT device can be detected using:
- Antivirus software
- Device reboot
- Digital signatures
- Regular software updates
Compromised bootloaders can be detected using digital signatures. Digital signatures verify the authenticity and integrity of the bootloader code, ensuring it hasn't been tampered with before executing it during the boot process.
AWS IoT Core is a platform that allows:
- Cloud computing services
- Developing mobile applications
- Managing databases
- Securely connecting and managing IoT devices
AWS IoT Core is a platform that allows securely connecting and managing IoT devices. It provides a suite of services for IoT, including device registration, communication, and data processing in the cloud. Cloud computing services, developing mobile applications, and managing databases are related but not the primary purpose of AWS IoT Core.
An example of M2H (Machine-to-Human) communication in IoT would be:
- A sensor transmitting data to a cloud server
- A smart thermostat adjusting the temperature based on room occupancy
- A smart refrigerator ordering groceries automatically
- Your smartphone alerting you to low battery
M2H (Machine-to-Human) communication involves machines or devices communicating with humans. Your smartphone notifying you of low battery is a clear example of this. It's a machine (smartphone) alerting a human (you) about an important status change, which is a common use case in IoT.
A manufacturing company wants to ensure that its machinery operates within safe temperature ranges. To achieve this, they should implement:
- Artificial Intelligence and Machine Learning
- Real-time monitoring and control systems
- Virtual reality simulations
- 3D printing technology
To ensure that machinery operates within safe temperature ranges, a manufacturing company should implement real-time monitoring and control systems. These systems use sensors to continuously measure the temperature of machinery and can automatically adjust operations or send alerts in case of temperature deviations, ensuring safety and efficiency.
What is the primary purpose of a secure boot in IoT devices?
- Enable remote control of the device
- Enhance battery life
- Improve device processing speed
- Protect the device from unauthorized firmware
Secure boot in IoT devices primarily aims to protect the device from unauthorized firmware, ensuring that only trusted code is executed during bootup. This helps safeguard against malicious software and unauthorized access.
