Definition of IoT
• What is IoT?
• ITU Definition:
• "A global infrastructure for the information society, enabling advanced services by
interconnecting (physical and virtual) things based on existing and evolving,
interoperable information and communication technologies."

"An IoT is a network that connects uniquely identifiable 'things' to the Internet. The
'things' have sensing/actuation and potential programmability capabilities. Through
the exploitation of the unique identification and sensing, information about the
'thing' can be collected and the state of the 'thing' can be changed from anywhere,
anytime, by anything.”
