Digital certificates in IoT devices primarily help in:
- Data Encryption
- Data Storage
- Device Authentication
- User Authentication
Digital certificates in IoT devices primarily aid in device authentication. These certificates ensure that the device is genuine and authorized to access or exchange data within the network. While data storage and encryption are important, they are not the primary role of digital certificates in IoT.
Imagine you are a historian tracing the roots of IoT. You find a reference to a project from the 1980s where machines communicated their status to a computer. This is most likely an example of:
- ARPANET
- Bluetooth Mesh
- M2M (Machine-to-Machine) Communication
- VoIP (Voice over Internet Protocol)
In the 1980s, machines communicating their status to a computer is a clear example of Machine-to-Machine (M2M) communication. This concept laid the foundation for the development of the Internet of Things (IoT) where devices and machines can communicate with each other autonomously.
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.
Smart thermostats and smart locks are examples of:
- Agricultural tools
- Home automation devices
- Smartphones
- Wearable IoT devices
Smart thermostats and smart locks are examples of home automation devices. They are designed to make homes more efficient, comfortable, and secure. Smart thermostats help control the temperature of a home, while smart locks enhance security by allowing remote access control.
________ tools in IoT help stakeholders understand patterns and insights from large datasets.
- Data analytics
- Debugging
- Encryption
- Protocol
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.
Over-the-Air (OTA) updates for IoT devices are essential for:
- Delivering bug fixes and feature enhancements remotely
- Ensuring the IoT device is always offline
- Managing IoT device security
- Reducing the initial cost of an IoT device
OTA updates are crucial for delivering bug fixes and feature enhancements remotely, ensuring that IoT devices can adapt, improve, and stay secure over time. These updates are typically delivered over the internet, allowing devices to be updated without physical access.
A company is developing a remote surgery solution where surgeons can operate from miles away. This solution would greatly benefit from the ________ feature of 5G.
- Energy Efficiency
- High Bandwidth
- Low Latency
- Wide Coverage
The low latency feature of 5G is critical for remote surgery. Low latency ensures minimal delay in data transmission, which is crucial in surgical procedures where real-time responses are essential. High bandwidth, wide coverage, and energy efficiency are also valuable but have different priorities in this scenario.
When considering bi-directional communication in IoT, the protocol often recommended due to its low overhead and real-time capabilities is ________.
- HTTP
- MQTT
- WebSockets
- XMPP
For bi-directional communication in IoT, the protocol often recommended due to its low overhead and real-time capabilities is WebSockets. WebSockets provide full-duplex communication channels over a single TCP connection. They are well-suited for scenarios where low latency and real-time data exchange are crucial, making them a popular choice in IoT applications.
