These systems are used in an environment where a large number of events (generally external) must be accepted and processed in a short time. Real time Operating Systems are very fast and quick respondent systems. RTOS are controlling traffic signal Nuclear reactors Control scientific experiments, medical imaging systems, industrial system, fuel injection system, home appliance are some application of Real Time operating system ![]() Resources can be used efficiently without wastage of time. ![]() So that they can communicate with each other. Real-time operating system synchronized the process. When a high priority process enters in system low priority process preempted to serve higher priority process. RTOS used Priority to execute the process. Interrupt Service Routine (ISR) serve the interrupt, raised by the system. RTOS is a time-sharing system based on clock interrupts. It is different from general purpose computer where time concept is not considered as much crucial as in Real-Time Operating System. ![]() The real-time operating system used for a real-time application means for those applications where data processing should be done in the fixed and small quantum of time.
