A critical component that enables seamless IoT and AI integration, especially in edge devices, is ________.
- Blockchain
- Connectivity
- Data Analytics
- Edge Computing
Edge Computing is a critical component for seamless IoT and AI integration in edge devices. It allows processing data closer to the source, reducing latency and enhancing efficiency.
Which of the following is considered a wearable IoT device?
- Fitness tracker
- Microwave oven
- Smart refrigerator
- Smart thermostat
A wearable IoT device is a device that can be worn on the body and is connected to the internet to collect and transmit data. A fitness tracker is a prime example of a wearable IoT device, as it's worn on the wrist to monitor health and activity data like steps, heart rate, and sleep patterns.
An energy company has embarked on an IoT project to monitor and predict the maintenance needs of its machinery. After defining the objectives, the next step they should focus on is:
- Data Collection and Sensor Deployment
- Data Visualization and Reporting
- Hardware Procurement
- Machine Learning Model Training
After defining objectives in an IoT project like this, the next crucial step is data collection and sensor deployment, as this is essential to gather the necessary data for predicting maintenance needs accurately.
The Raspberry Pi, a popular IoT device, supports programming in:
- C#
- Python
- Ruby
- Swift
The Raspberry Pi supports programming in Python, which is one of the most commonly used languages for developing applications on this platform. While other languages like C# and Ruby can be used on the Raspberry Pi, Python is particularly popular due to its extensive support and libraries.
The phase where potential risks and challenges of an IoT project are identified is called ________.
- Risk Analysis
- Risk Assessment
- Risk Identification
- Risk Mitigation
In IoT projects, the phase where potential risks and challenges are identified is known as "Risk Identification." This process involves recognizing and documenting possible issues that could impact the project's success.
A company discovered that their IoT devices were participating in a DDoS attack without their knowledge. This is likely due to:
- Inadequate firmware updates
- Lack of security measures
- Overuse of battery power
- Poor network connectivity
A company's IoT devices participating in a DDoS attack could be due to a lack of proper security measures. IoT devices, if not adequately secured, can be vulnerable to malicious actors who compromise their operation and use them as bots in a DDoS attack. Ensuring security measures like encryption, strong authentication, and regular security updates is crucial in such cases.
Which of the following is a common security threat to IoT devices?
- Data breaches
- Excessive battery usage
- High processing power
- Poor Wi-Fi connectivity
Data breaches are a common security threat in IoT, as unauthorized access to IoT data can have serious consequences, such as privacy violations and misuse of sensitive information.
AI algorithms that enable IoT devices to learn from data and improve over time are known as ________.
- Deep Learning
- Machine Learning
- Reinforcement Learning
- Self-Improving Algorithms
In the context of IoT, AI algorithms that enable devices to learn from data and enhance their performance over time are referred to as "Reinforcement Learning" algorithms. These algorithms learn by trial and error, which is valuable in IoT applications.
Wearable devices that provide feedback to users about their health metrics primarily use the ________ communication model.
- Bluetooth
- Feedback
- Internet
- Telepathic
Wearable devices primarily use the "Bluetooth" communication model to send health metrics and data to the user's smartphone or other devices. Bluetooth is a short-range wireless communication technology commonly used in wearables for connectivity.
Which sensor would be most appropriate for monitoring the shipment of perishable goods to ensure they remain within a safe temperature range?
- Light sensor
- Pressure sensor
- Proximity sensor
- Temperature sensor
A temperature sensor would be the most appropriate choice for monitoring the shipment of perishable goods. Temperature sensors, often referred to as thermometers or thermocouples, measure the temperature of their surroundings. In this context, they are crucial for ensuring that perishable items remain within a safe temperature range during transportation, such as in refrigerated trucks or containers.
