Can IoT work without Internet?
An IoT system consists of sensors/devices which “talk” to the cloud through some kind of connectivity. Once the data gets to the cloud, software processes it and then might decide to perform an action, such as sending an alert or automatically adjusting the sensors/devices without the need for the use
Is IoT a network?
The word does not refer to the Internet itself. In short, you could say the Internet for Things focuses on the Internet while the IoT focuses on the devices (Things). But IoT connectivity can be cumbersome.True IoT solutions should allow direct access to any device from any device.
