M2M is an acronym for Machine to Machine. As the name describes, proactive human involvement is seldom part of the one or two-way communication process.
The idea behind the technology is to streamline the way data is collected from physical devices and incorporated into IT systems – without having to rely on people to intervene within the process.
IoT is an acronym for Internet of Things. The technical definition of The Internet of Things (IoT) is the network of physical objects accessed through the Internet. These objects contain embedded technology to interact with internal states or the external environment. In other words, when an object can sense and communicate, it changes how and where decisions are made, and who makes them.
