A Real-Time Operating System (RTOS) is a specialized type of operating system designed to manage hardware resources and run applications that require precise timing and high reliability. Unlike general-purpose operating systems, an RTOS ensures that tasks are completed within strict time constraints, making it ideal for applications in fields like automotive, aerospace, and medical devices. RTOSs prioritize tasks based on their urgency, allowing critical processes to execute without delay. This capability is essential for systems that control robotics, industrial automation, or telecommunications, where even a slight delay can lead to failures or safety hazards. By providing predictable performance, RTOSs help developers create efficient and dependable systems.
