Hi, I was asked the question in the title some time ago. I had some real-time embedded system experience but with RTOS. A watch-dog can avoid a task not called in a real-time system. But in a RTOS, what is the right answer for it? I knew task priority, a timer triggered event all can influence a task execution. But they didn't look like the correct answer. What is the right answer do you thi...
