Answer 1

The return value for the fork system call in UNIX is Zero for the child process and a nonzero integer (process ID of the child) for the parent process.

Step-by-step explanation:

The return value for the fork system call in UNIX is Zero for the child process and a nonzero integer (process ID of the child) for the parent process.

The fork system call in UNIX is used to create a new process by duplicating the existing process. The new process is called the child process, and the existing process is called the parent process.
