Which statement is not true about process O in the Unix operating system ?

  • A.Process O is called init process.
  • B.Process O is not created by fork system call.
  • C.After forking process 1, process O becomes swapper process.
  • D.Process O is a special process created when system boots.

Answer: A

The statement that is not true is that process 0 is called the init process. Process 0 is the first, special process that the kernel creates when the system boots, and it is not made by the fork system call. It forks process 1, which is the init process, and afterwards process 0 becomes the swapper (scheduler) process.

The other three statements are true: it is not created by fork, it becomes the swapper after forking process 1, and it is a special process created at boot.
