For secure communication, IoT devices often employ ________ to ensure data integrity and confidentiality.
- Authentication
- Encryption
- Firewall
- Latency
IoT devices employ encryption to ensure data integrity and confidentiality. Encryption is the process of converting data into a secure format that can only be read with the correct decryption key. Authentication, Firewall, and Latency are important in IoT, but they do not directly ensure data integrity and confidentiality as encryption does.
Data analytics in IoT not only helps in understanding the data but also in ________ based on the insights.
- Encrypting
- Predicting
- Storing
- Transmitting
Data analytics in IoT not only helps in understanding the data but also in "Predicting" based on the insights. IoT data analytics uses historical and real-time data to identify patterns and trends, enabling predictions that can be valuable for decision-making and improving processes.
How does 5G technology primarily benefit the Internet of Things (IoT)?
- High Power Consumption
- Limited Device Connectivity
- Low Latency Communication
- Slow Data Transfer Speeds
5G's primary benefit for IoT is low latency, which ensures quick data transmission. This is crucial for real-time applications like remote surgery and autonomous vehicles.
The General Data Protection Regulation (GDPR) affects IoT devices by:
- Requiring all IoT devices to have internet connectivity
- Imposing strict data protection and privacy requirements
- Regulating the size and weight of IoT devices
- Mandating the use of open-source software in IoT devices
GDPR primarily affects IoT devices by imposing strict data protection and privacy requirements. IoT devices often collect and process personal data, making GDPR compliance crucial.
The integration of ________ in clothing has led to the development of smart garments in the wearable IoT sector.
- Batteries
- Conductive fabrics
- Microcontrollers
- Sensors
The integration of conductive fabrics in clothing has enabled the development of smart garments in the wearable IoT sector. Conductive fabrics allow for the integration of sensors, microcontrollers, and power sources directly into clothing, enabling features like temperature monitoring, fitness tracking, and communication in the form of smart textiles.
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.
