Internet of things

The  Internet of things  ( IoT ) is the network of physical devices, vehicles, home appliances and other items  embedded  with  electronics ,  software ,  sensors ,  actuators , and  network connectivity  which enables these objects to connect and exchange  data . Each thing is uniquely identifiable through its embedded computing system but is able to inter-operate within the existing  Internet  infrastructure. Experts estimate that the IoT will consist of about 30 billion objects by 2020. It is also estimated that the global market value of IoT will reach $7.1 trillion by 2020. The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention. When IoT is augmented with sensors and actuators, the technology becomes an instance of the more
