What are M2M (Machine to Machine) and the IoT (Internet Of Things)?

M2M stands for Machine to Machine. As the term says, proactive human involvement is rarely part of the one-way or two-way communication process.The idea behind the technology is to simplify the way data is collected from physical devices and embedded in IT systems [connectivity], without having to rely on people to intervene in the process.
IoT is the acronym for Internet of Things. The technical definition of the Internet of Things (IoT) is the network of physical objects accessible via the Internet. These objects contain embedded technology that allows interaction with internal states or the external environment. In other words, when an object can perceive and communicate, it changes how and where decisions are made and who makes them.
