Assertion (A): Cascading termination occurs when an operating system automatically terminates all child processes if the parent process terminates.
Reason (R): In some systems, a child process cannot exist or run independently if its creator/parent process has ceased to exist.
Assertion (A) is True:
Cascading termination is a mechanism used by some operating systems where the termination of a parent process automatically triggers the termination of all its child processes.
Reason (R) is True:
In certain systems, child processes are not allowed to persist or run independently once their creator or parent process has ceased to exist.
Correct Explanation:
Reason (R) provides the exact rationale behind cascading termination—that child processes cannot exist independently of their parents—which explains why the operating system automatically terminates them when the parent dies.
