The Internet of Things 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 communications networks. The Internet of Things 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. Older fields of embedded systems, wireless sensor networks, control systems, automation, independently and collectively enable the Internet of Things.
