What is RTOS?

Real-Time Operating System

A real-time operating system (RTOS) is a compact operating system that schedules tasks with deterministic, bounded timing, guaranteeing that time-critical operations run within their deadlines.

An RTOS lets firmware juggle many concurrent tasks predictably — essential for motor control, communications, and safety systems. Common choices include FreeRTOS and Zephyr.
