What enables IoT devices to gather data and exchange it over the network?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Actuators and sensors.
Actuators and sensors are key components that enable IoT (Internet of Things) devices to gather data and exchange it over a network.
Sensors are responsible for detecting and measuring physical changes in the environment, such as temperature, humidity, light, motion, or pressure. They convert these physical parameters into signals that can be read and processed by the device. For example, a temperature sensor in a smart thermostat collects temperature data from a room.
Actuators, on the other hand, perform actions based on the processed data or commands received from the network. They convert electrical signals into physical actions, such as turning on a fan, adjusting a valve, or moving a robotic arm.
