No, **RTOS** (Real-Time Operating System) is not a programming language. It is an **operating system** designed to manage hardware resources and run applications in real-time environments, where processing time is critical.
In an RTOS, tasks must be completed within a certain time frame, which makes it ideal for applications like robotics, automotive systems, industrial control, and other embedded systems where precise timing is crucial.
While programming languages like C or C++ are often used to develop software that runs on an RTOS, the RTOS itself is the system that controls how tasks are scheduled and executed.
