    An operating system (OS) is responsible for managing the hardware resources of a computer and hosting applications that run on the computer. An RTOS performs these tasks, but is also specially designed to run applications with very precise timing and a high degree of reliability. This can be especially important in measurement and automation systems where downtime is costly or a program delay could cause a safety hazard.

    Hello friends,

    In general, an operating system (OS) is responsible for managing the hardware resources of a computer and hosting applications that run on the computer. An RTOS performs these tasks, but is also specially designed to run applications with very precise timing and a high degree of reliability. This can be especially important in measurement and automation systems where downtime is costly or a program delay could cause a safety hazard.

    Best regards

    A real time operating system is a computing environment.A RTOS is responsible for managing the hardware resources of a computer.
    Real time operating system are often required in small embedded operating system that are packaged as part of microdevices.
    A real time OS has an advanced algorithm for scheduling.

    Hi
    Real-time system is a system in which the correctness of the output depends not only on the correctness of the calculation result, but also the time in which the result is counted.

    Real time OS are very fast and quick respondent systems. 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 processing requires quick transaction and characterized by supplying immediate response.

    In real time Operating System there is a little swapping of programs between primary and secondary memory. Most of the time, processes remain in primary memory in order to provide quick response, therefore, memory management in real time system is less demanding compared to other systems.
