The quick adoption of smart phones reflects movement towards an Internet-based society including the internet of Things, a term that refers to the growing number and variety of physical objects that communicate with each other through the internet. No longer is the Internet limited to a laptop or smart phone—it increasingly connects previously unconnected devices, leading to cars capable of driving themselves and medical devices that can provide remote, real-time updates to hospitals. Over 50 billion objects are expected to be connected to the Internet by 2020.
