What is an example of an M2M connection in the IoT?
- A user sends an email over the Internet to a friend.
- Sensors in a warehouse communicate with each other and send data to a server block in the cloud.
- Redundant servers communicate with each other to determine which server should be active or standby.
- An automated alarm system in a campus sends fire alarm messages to all students and staff.
Explanation: The Internet of Things (IoT) connects devices that traditionally are not connected to the Internet, such as sensors and actuators. A machine-to-machine (M2M) connection is unique to the IoT in that devices are connected together and communicate with each other. These devices can send data to a server block in the cloud for analysis and further operation change.
