0 0 votes I think both suspend ready and suspend wait is correct as both signifies that the process is in the secondary memory and hence from this state only its best suited to swap it back into the main memory!

The transition can also be made for the BLOCKED process if there are READY processes available, and the OS determines that the READY process it would like to dispatch requires more main memory to maintain adequate performance. SUSPEND BLOCKED then SUSPEND READY A process in the SUSPEND BLOCKED state is moved to the SUSPEND READY state when the event for which it has been waiting occurs. Note that this requires the state information concerning suspended processes be accessible to the OS. SUSPEND READY then READY When there are no READY processes in main memory, the OS will need to bring one in to continue execution. In addition, it might be the case that a process in the READY SUSPEND state has higher priority than any of the processes in the READY state. In that case, the OS designer may dictate that it is more important to get at the higher priority process than to minimise swapping. SUSPENDED but READY Normally, the OS would be designed so that the preference would be to suspend a BLOCKED process rather than a READY one. 0 0 replyShare Please log in or register to add a comment.
