The IoT is made up of all the physical devices that have the ability to connect and share data.
They might connect using:
- Ethernet cable
- Wi-Fi
- Bluetooth
- Mobile internet
- Another radio wave-based technology.
They might connect to:
- Each other
- Local hub
- Local hub and cloud service
- Cloud service
- Internet service.
Typically, these devices have connectivity for a reason. Your smart light bulbs might use Bluetooth or Wi-Fi to receive scheduled instructions to dim, brighten, or change colour. Your smart speaker might connect to the internet to find the answer to a question you asked or to use a cloud service to process a request.
