The Internet of Things (IoT) is a vast network of devices that share information using different Internet protocols. It is comprised of different kinds of interactions between devices, online servers, and humans. Most interactions involve communication between one IoT device and another, or communication between an IoT device and a human. Both forms of interaction can either be direct or via a web server (indirect).
Though human interaction in IoT systems is important, it is not always needed. You can create autonomous systems that do not require any human input to operate. This is made possible by M2M interaction. In such systems, the different IoT devices send data to each other and execute different actions depending on the input they receive. This eliminates the need for human intervention.
M2M is a term that is used to describe technology that allows communication between networked devices. The devices use network resources to exchange data with remote application...
