A multi-user, multi-processing operating system cannot be implemented on hardware that does not support:

System calls are usually invoked by using:

Which of the following actions is/are typically not performed by the operating system when switching context from process $$A$$ to process $$B$$ ?

Consider the following C function definition

int Trial (int a, int b, int c)
{
       if ((a > = b) && (c < b)) return b;
       else if (a > = b) return Trial (a,c,b);
       else return Trial (b,a,c);
}

The function Trial:
