RTOS provide real-time multi-task and communication scheme between the tasks,
You explain RTOS just by it's name "real time OS".
You didn't explain what is "real time" mean?
Ok, let suppouse you are making a robot with two hands - one is throwing a glass beer bottle up and second arm is catching this bottle in the fly.
If you will control hands in MS Windows, then all bottles will be broken no beer will be left. But if you install QNX then all of them will be safe. That is why Microsoft is a big danger for the World!
Now you see what is "real time" - it is time in real world.
