Overviews of IoT from Wikipedia and IIoT from GE. The GE link makes the following statement comparing IoT with IIot:
IoT from CiscoOne perspective is to think of the Industrial Internet as connecting machines and devices in industries such as oil and gas, power generation, and healthcare, where there is more at stake or where system failures and unplanned downtime can result in life-threatening or high-risk situations. On the other hand, the Internet of Things tend to include consumer-level devices such as heart monitoring fitness bands or smart home appliances. They are functional and can provide conveniences but do not typically create emergency situations if downtime were to occur.
