Looking up specific API functions and configuration options.

A standard operating system like Windows or macOS focuses on throughput and user experience. In contrast, a Real-Time Operating System (RTOS) focuses on determinism. In an RTOS, the timing of an operation is just as important as the result itself. FreeRTOS allows you to break your code into independent tasks, each with its own priority, ensuring that critical functions always get CPU time when they need it. Core Concepts of FreeRTOS
