The correct answer to the question "The ready queue is generally stored as a ____." is Linked List.

Explanation

In operating system design, a ready queue is a data structure that holds all the processes that are in the ready state, waiting for CPU time to execute. Among the options provided, a linked list is the most efficient method for organizing this queue.

1. Array: While it is possible to implement a queue using an array, it has limitations such as fixed size, which can lead to wasted space or the need for resizing.
2. Stack: A stack operates on a Last-In, First-Out (LIFO) principle, which is not suitable for a ready queue that typically requires First-In, First-Out (FIFO) processing.
3. Linked List: A linked list can dynamically grow and shrink, allowing for efficient memory use. It enables easy insertion and deletion of processes in the queue without the need for shifting elements, making it ideal for managing variable-length processes in the ready state.
4. None of the above: This option is not applicable since a linked list is indeed a valid choice.

Thus, the best answer is a Linked List as it provides the necessary flexibility and efficiency for maintaining the ready queue in an operating system.
