We need the Internet of things because it will connect our cars, doctors, and even our home appliances. It will change our life into a better one. The Internet of things makes your life easier and more convenient to live. For example, in the near future all you need to do is to swipe on your smart watch and all your doors will automatically open. The Internet of things or IOT is the next paradigm shift in the data world. IOT will be a connected network of physical devices, vehicles, buildings and other objects capable of sensing the environment and wirelessly transmitting data via the internet. Billions (maybe trillions) of tiny, low-power, wireless devices will connect through a vast network of cloud computing services.
