IoT vs M2M
Definition
M2M (Machine-to-Machine): M2M refers to the direct exchange of data between machines or devices without human intervention.
IoT (Internet of Things): IoT is a network of interconnected devices, sensors, applications, and services that communicate through the Internet to collect, process, and share data.
