Machine to machine refers to direct communication between devices using any communications channel, including wired and wireless.

The Internet of things (IoT) is the inter-networking of physical devices, vehicles (also referred to as "connected devices" and "smart devices"), buildings, and other items—embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data.

In 2013 the Global Standards Initiative on Internet of Things (IoT-GSI) defined the IoT as "the infrastructure of the information society." The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention.

When IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, virtual power plants, smart homes, intelligent transportation and smart cities.

Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure.

Experts estimate that the IoT will consist of almost 50 billion objects by 2020.

A subscriber identity module or subscriber identification module (SIM) is an integrated circuit that is intended to securely store the international mobile subscriber identity (IMSI) number and its related , which are used to identify and authenticate subscribers on mobile telephony devices (such as mobile phones and computers).

It is also possible to store contact information on many SIM cards.

SIM cards are always used on GSM phones; for CDMA phones, they are only needed for newer LTE-capable handsets.

SIM cards can also be used in satellite phones.

A router is a networking device that forwards data packets between computer networks.

Routers perform the traffic directing functions on the Internet.

A data packet is typically forwarded from one router to another router through the networks that constitute the internetwork until it reaches its destination node.
