❓ Frequently Asked Questions
What is IoT Fundamentals?
IoT Fundamentals are the basic principles and technologies that enable the Internet of Things: interconnected devices with sensors and systems that can collect, exchange, and analyze data.
What are the main components of an IoT system?
Embedded devices with microcontrollers, sensors and actuators, connectivity (Wi-Fi, cellular, Bluetooth, etc.), gateways or edge devices, and cloud or edge processing for data storage and analytics.
How do IoT devices communicate and share data?
Devices connect over networks, collect data with sensors, send it through gateways to cloud or edge processors where it is stored, analyzed, and used to trigger actions; security measures like encryption and authentication are important.
What is edge computing in IoT?
Edge computing processes data near the source (on local devices or gateways) to reduce latency and bandwidth needs, while cloud processing handles heavier analytics.
What is the difference between sensors and actuators in IoT?
Sensors measure and report environmental data (temperature, humidity, etc.), whereas actuators perform actions in the physical world (adjust a valve, switch a motor) based on processed data.
