In computing, particularly in the context of the Unix operating system and its workalikes, fork is an operation whereby a process creates a copy of itself. It is an interface which is required for compliance with the POSIX and Single UNIX Specification standards.
What is zombie process in OS?
On Unix and Unix-like computer operating systems, a zombie process or defunct process is a process that has completed execution (via the exit system call) but still has an entry in the process table: it is a process in the “Terminated state”.
Why is fork () used?
The purpose of fork() is to create a new process, which becomes the child process of the caller. After a new child process is created, both processes will execute the next instruction following the fork() system call.
What is safe state in OS?
A state of the system is called safe if the system can allocate all the resources requested by all the processes without entering into deadlock. If the system cannot fulfill the request of all processes then the state of the system is called unsafe.
