State the difference between IoT and M2M.

Answer»

IoT (Internet of Things): It is referred to as a network comprised of interconnected PHYSICAL objects that are capable of collecting and exchanging data. These devices contain embedded systems (software, electronics, networks, and sensors) that are able to collect data about the surrounding environment, transmit data over a network, respond to remote commands, or take actions based on data collected. The Internet of Things (IoT) is a subset of M2M (Machine to Machine) technology. In IoT, two machines communicate without human intervention, making it a part of M2M. 

M2M (Machine to Machine): In M2M, devices communicate with each other directly via wired or wireless channels, without any human interaction. It enables devices to communicate and share data with each other without RELYING on the internet. Several applications of M2M communications are available, including security, TRACKING, and tracing, manufacturing, and facility management. 

IoTM2M
It is a network of connected devices (via the Internet) that have the ability to collect, process, and transmit data automatically without human intervention.   It allows two or more machines to communicate directly and perform certain tasks without requiring human intervention.  
In addition, IoT enables objects to interact with the internal and/or external environments, THEREBY INFLUENCING their decision-making.The M2M model exhibits some degree of intelligence. Devices capture data and share it with other connected devices, forming an intelligent network.
It facilitates cloud-based communication.   End-to-end communication between devices/machines is supported.  
In order to improve the end-user experience, data is shared between other applications.  Only parties communicating with each other have access to the data. 
Internet access is usually required for devices to communicate and share data.   Devices don't usually require an Internet connection for communication.  
Many machines are able to communicate over the internet.  The communication between machines is limited to one at a time.   
Open API integrations are supported. Open API integrations are not supported.  
A number of Internet protocols are used, including HTTP, FTP, and Telnet. Communication technologies and traditional protocols are used.
