The process state transition diagram of an operating system is as given below:

 

Which of the following statement is correct?

A)Round-Robin scheduling algorithm is used in the given operating system.

B)This operating system can’t support program from multiple users.

C)FCFS or SJF policy can be used by the operating system.

D)CPU will have to remain idle for long if process is waiting for IO completion.

Comments

C is the answer..

as there is no transition from running to ready state so non preemtive policy should have been used i.e either fcfs or sjf ..

for the same reason of above option a is wrong .

for d) if some process goes in blocked state cpu will take any other process from ready state so it will never be idle
