OS Processes
Suppose that a process is in “Blocked” state waiting for some I/O service. When the service is completed, it goes to the __________
Running state
Ready state
Suspended state
Terminated state
Ready state
Suppose that a process is in “Blocked” state waiting for some I/O service. When the service is completed, it goes to the ready state. Process never goes directly to the running state from the waiting state. Only processes which are in ready state go to the running state whenever CPU allocated by operating system.
