Answer 2

RTOS is not a commonly used operating system:

• A real-time operating system (RTOS) is an operating system (OS) for real-time applications that processes data and events that have critically defined time constraints.
• A RTOS is distinct from a time-sharing operating system, such as Unix, which manages the sharing of system resources with a scheduler, data buffers, or fixed task prioritization in a multitasking or multiprogramming environment.
• Processing time requirements need to be fully understood and bound rather than just kept as a minimum. All processing must occur within the defined constraints.
• Real-time operating systems are event-driven and preemptive, meaning the OS is capable of monitoring the relevant priority of competing tasks, and make changes to the task priority.
• Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts.
