IoT 面试题与答案
问题 11. Explain the concept of IoT gateway.
An IoT gateway acts as a bridge between IoT devices and the cloud, aggregating and preprocessing data before transmitting it to the cloud for further analysis.
Example:
A gateway collecting data from sensors in an industrial setting before sending it to the cloud.
问题 12. What is Fog Computing in the context of IoT?
Fog Computing extends cloud computing to the edge of the network, allowing data processing to occur closer to the data source, reducing latency and improving efficiency.
Example:
Processing data from surveillance cameras at the network edge instead of sending it to a distant cloud server.
问题 13. What is the role of AI (Artificial Intelligence) in IoT?
AI in IoT enables devices to analyze data, make decisions, and learn from patterns, enhancing automation and intelligence in connected systems.
Example:
A smart thermostat learning user preferences and adjusting temperature settings accordingly.
问题 14. How does IoT impact industries like healthcare?
In healthcare, IoT can monitor patients remotely, track medical equipment, and optimize healthcare processes, leading to improved patient care.
Example:
Wearable devices tracking a patient's vital signs and sending data to healthcare providers in real-time.
问题 15. What is LPWAN (Low Power Wide Area Network) in IoT?
LPWAN is a type of wireless communication network designed for long-range communication with low power consumption, making it suitable for IoT devices with low energy requirements.
Example:
Connecting battery-powered sensors in agriculture fields for soil monitoring.
