Process States

A total of nine states are acknowledged by the UNIX system. They are like as follow:

User running                                                   Executing in user mode

 

Kernel running                                                Executing in kernel mode

 

Ready to run, in memory                                Ready to run the instant the kernel schedules it.

 

Asleep in memory                                           Unable to execute until an event take place; process is within the main memory

 

Ready to run, swapped                                   Process is set to run, but the swapper should swap the process into the main memory before the kernel is able to schedule to execute.                      

 

Sleeping, swapped                                          The process is stay an event and has been swapped to secondary storage

 

Preempted                                                       Process is recurring from kernel to user mode, other than the kernel preempts it and does a process switch to schedule another process

 

Created                                                           Process is recently created and not yet ready to run

 

Zombie                                                            Process no longer be present, other than it leaves a record for its parent process to collect
