A network of devices that have an embedded hardware and software to…

The Internet of Things (IoT) refers to a network of physical objects — each embedded with sensors, hardware and software — that connect over a network and communicate with one another, exchanging data automatically without requiring direct human intervention.

The question describes exactly this: devices carrying embedded hardware and software that connect and exchange data with other devices on the same network. That is the defining feature of IoT, so the correct answer is Internet of Things.

• Machine Learning is an AI technique in which systems learn patterns from data to make predictions — an algorithmic method, not a network of interconnected devices.

• Deep Learning is a subfield of Machine Learning that uses multi-layered neural networks to learn from large datasets — a modelling method, not a device network.

• Robotics is the engineering discipline concerned with designing, building and operating robots — it deals with physical machines performing tasks, not with networking everyday devices to exchange data.
