Machine-to-Machine

Machine-to-machine (M2M) is when different machines talk to each other without the help of humans. It's like two robots who can understand each other without needing a person to tell them what to say.

Let's imagine you have a toy robot that can move around your room by itself. Now, your robot wants to communicate with other toys, like a toy train or a toy airplane. Normally, you would have to tell the robot to talk to the other toys, but with M2M, the robot can do it by itself.

So, your robot sends a message to the toy train, saying "Hello train, where are you?" The toy train receives the message and sends a reply back to the robot, saying "I'm over here, near the toybox."

The robot can then use this information to go find the train and play with it. This is just like when you talk to your friends and ask them where they are so you can go hang out with them.

In the real world, M2M is used in many different ways, like when factories use machines to communicate with each other to make products, or when hospitals use machines to monitor patients and send information to doctors.

Overall, M2M is like having a group of smart toys that can talk to each other and work together to do things without needing you to tell them what to do.
