We have been connecting devices and “things” to the Internet and other networks for decades. Technologies such as automated teller machine (ATM), wireless sensor networks (WSN), machine to machine (M2M), and other connected devices are not new at all. However, this does not mean by definition that all these systems and devices are part of what we know today as the IoT. In other words, not all connected devices are IoT devices; however, all IoT devices are connected devices. Furthermore, in IoT we use the Internet Protocol (IP), IPv6,¹ in particular. Hence, we only pronounce the word Internet of Things when “things” are uniquely addressable.

There are many IoT definitions, and there isn't a universal one. It depends from which angle it is being looked at: Technology angle, application angle, or the industry angle.

However, from a general perspective IoT could be defined as the interconnection of devices with embedded sensing, actuating, and communication capabilities. Data in IoT are collected, processed, coordinated, and communicated through embedded electronics, firmware, and communication technologies, protocols, and platforms.
