What is an intertask communication in RTOS?

Intertask communication in a Real-Time Operating System (RTOS) refers to the mechanisms that allow different tasks or threads to exchange data and synchronize their activities. This can involve various methods such as message queues, semaphores, and shared memory. Effective intertask communication is crucial for ensuring that tasks operate cohesively, especially in time-sensitive applications, where the timing and order of operations can significantly impact system behavior. By facilitating communication, an RTOS helps in managing resource sharing and coordination among concurrent tasks.
