What are real-time operating systems?

What are real-time operating systems ? Pay attention to a detailed study of RTOS. First of all, these are special types of operating system that differ from universal OS in their performance and speed in the worst situations. There are many concepts that reveal specifics:

- RTOS - a system that is able to provide the necessary service for a certain period of time;

- a real-time system that is distinguished by constant availability and the time of the processed information is invisible to users;

- “fast system”, where not the response time of the RTOS comes to the fore, but the sufficiency of time to work with the application.

The RTOSs differ from general-purpose systems in the deterministic nature of the work, which is due to the strict control of the time spent on processing tasks. The concept of “determination” describes a predetermined time interval for which one real-time program is executed.
