So what is Internet of Things (IoT)
“A dynamic global network infrastructure
with self-configuring capabilities
based on standard and interoperable communication protocols
where physical and virtual “things” have identities,
physical attributes and use intelligent interfaces,
and are seamlessly integrated into the information network,
often communicate data associated with users and their environments”
The Fourth Industrial Revolution!
