What is the difference between IoT and machine to machine?
The Internet of Things (IoT) refers to the network of physical objects—devices, vehicles, buildings and other items embedded with electronics, software, sensors, and network connectivity—that enables these objects to collect and exchange data. Machine to machine (M2M) communication is similar in concept to the IoT, but is more focused on direct machine-to-machine communication, typically without involving humans. It refers to communication between two or more machines using a wireless network, with one machine acting as the master and the other as the slave. The goal of M2M communication is to automate processes, with minimal human intervention, and this is what sets it apart from the Internet of Things.
