The term "Internet of things" (IoT) refers to physical objects (or groups of such objects) equipped with sensors, computing power, software, and other technologies that communicate with one another and exchange data through the Internet or other communications networks.
Devices just need to be connected to a network and be individually reachable, not the public internet, which has led to criticism of the term "Internet of things."
The fusion of numerous technologies, such as ubiquitous computing, widely available sensors, sophisticated embedded systems, and machine learning, has caused the sector to advance.
The Internet of things is enabled both individually and collectively by the traditional domains of embedded systems, wireless sensor networks, control systems, and automation (including home and building automation).
Ashley Baker has been the webmaster for Berryhill Finance only ten days when she received an e-mail that threatened to shut down Berryhill's website unless Ashley wired payment to an overseas account. Ashley was concerned that Berryhill Finance would suffer huge losses if its website went down, so she wired money to the appropriate account. The author of the e-mail successfully committed cyber-extortion.
