This is a list of real-time operating systems (RTOSs). This is an operating system in which the time taken to process an input stimulus is less than the time lapsed until the next input stimulus of the same type.
The article "Usage share of operating systems" provides a broader, and more general, comparison of operating systems that includes servers, mainframes and supercomputers. Because of the large number and variety of available Linux distributions , they are all grouped under a single entry; see comparison of Linux distributions for a detailed ...

The operating system is also a set of services which simplify development and execution of application programs.
A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An 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 ...
