IoT Pertanyaan dan Jawaban Wawancara
Ques 1. What is IoT?
IoT, or Internet of Things, refers to the network of interconnected physical devices that communicate and exchange data with each other over the internet.
Example:
Smart thermostats, wearable fitness trackers, and connected home appliances.
Ques 2. Explain the concept of 'Edge Computing' in IoT.
Edge Computing involves processing data near the source of data generation, rather than relying solely on a centralized cloud server. It helps reduce latency and bandwidth usage.
Example:
Analyzing sensor data on a factory floor instead of sending it to a cloud server for processing.
Ques 3. What are IoT protocols, and name a few examples?
IoT protocols are communication standards used for device-to-device and device-to-cloud communication. Examples include MQTT, CoAP, HTTP, and AMQP.
Example:
Using MQTT for lightweight and efficient messaging between IoT devices.
Ques 4. Differentiate between IoT and M2M (Machine-to-Machine) communication.
IoT involves a broader concept of interconnecting multiple devices and systems, while M2M focuses on direct communication between machines without human intervention.
Example:
IoT includes smart cities with interconnected devices, whereas M2M might involve sensors communicating in an industrial setting.
Ques 5. What is MQTT, and how is it used in IoT?
MQTT (Message Queuing Telemetry Transport) is a lightweight and efficient messaging protocol for IoT. It is used to publish and subscribe to messages between devices.
Example:
A smart home system using MQTT to control lights and receive sensor data.
