In the process lifecycle, the queue where processes wait for CPU allocation is called the ____ queue.
Choose the correct answer:
A.
Ready
(Correct Answer)
B.
Waiting
C.
Job
D.
Device
Correct Answer:
Ready
Explanation
In an Operating System, the Ready Queue is a specific data structure where all processes that are loaded into the main memory and are prepared to execute reside. These processes are waiting for the scheduler to select them and allocate CPU time so they can transition into the "Running" state.
To better understand the process lifecycle, we can look at the transitions:
Job Queue: Contains all processes in the system.
Ready Queue: Contains processes residing in main memory that are ready and waiting to execute.
Waiting Queue: Contains processes that are blocked, waiting for an I/O event or another resource to become available.
In terms of the CPU lifecycle, the relationship can be summarized as:
StateReadySchedulerStateRunning
Processes in the Ready state have satisfied all necessary requirements (like memory allocation) to execute, lacking only the CPU time itself. Therefore, the queue containing these processes is definitively the Ready Queue.
