The different Process States
READY – The process is waiting to be assigned to a processor. RUNNING – Instructions are being executed. WAITING – The process is waiting for some event to occur(such as an I/O completion or reception of a signal). TERMINATED – The process has finished execution.
What are the reasons for process creation?
There are four principal events that cause a process to be created:
- System initialization.
- Execution of process creation system call by a running process.
- A user request to create a new process.
- Initiation of a batch job.
How does OS create a process?
Process creation is achieved through the fork() system call. The newly created process is called the child process and the process that initiated it (or the process when execution is started) is called the parent process. After the fork() system call, now we have two processes – parent and child processes.
