  • This support can be included inside the Operating System.
    it improves the
    efficiency in the context changes, memory management and other
    parameters typical of the Operating System performance
    This way, the computational entities of the system not only can
    execute code in a sequential way, but can also be aware of their
    environment and take proactive actions without external interaction.
