Your question is RTOS vs Bare Metal Trade-offs. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What are the advantages and disadvantages of using a Real-Time Operating System (RTOS)?
Discuss the trade-offs in an embedded system, including deterministic timing, scheduling, interrupt handling, resource consumption, portability, development complexity, reliability, and security. Contrast an RTOS with bare-metal firmware and a general-purpose operating system, and explain when an RTOS is the appropriate choice.
