What is the working of rtos?

A Real-Time Operating System (RTOS) manages hardware resources and scheduling of tasks to ensure timely execution of events. It operates by prioritizing tasks based on their urgency, allowing high-priority tasks to preempt lower-priority ones. An RTOS typically employs mechanisms like task scheduling, inter-task communication, and resource management to maintain deterministic behavior, ensuring that critical tasks meet their deadlines consistently. This is crucial in applications where timing is critical, such as embedded systems in automotive or medical devices.
