Internet of Things (IoT)
Humanity had been putting computing chips on more and more things to allow them to exchange data with one another over the Internet. The resultant communication network is called the Internet of Things or IoT.
Technically speaking, the term - Internet of Things encompasses anything that can connect to the Internet, directly or indirectly.
These things can include computing devices that you had been using day-to-day; your computer, smartphone, or tablet.
These things can also be electronic devices that we don't use for work; your car or Raspberry Pi Zero W CCTV.
