Internet of Things
The Internet of Things connects devices and systems that use sensors or actuators to interact with the physical world.
The Internet of Things describes connected devices and systems that interact with the physical world. In NIST's IoT-system model, networked components use sensors or actuators to observe or affect a physical entity.
A device may communicate through a local network, a gateway, or a related cloud service. Its connectivity and interaction with physical equipment create security and privacy considerations throughout the system's life.
