Internet of things (IoT) describes devices with sensors, processing
ability, software and other technologies that connect and exchange data with
other devices and systems over the Internet or other communication networks.
The IoT encompasses electronics, communication, and computer science
engineering. "Internet of things" has been considered a misnomer because
devices do not need to be connected to the public internet; they only need to
be connected to a network and be individually addressable.
The field has evolved due to the convergence of multiple technologies,
including ubiquitous computing, commodity sensors, and increasingly powerful
embedded systems, as well as machine learning.
