Question

Quizplus · Accepted Answer

A set of processes is said to be deadlocked when each process in the set is waiting for a resource held by another process in the set, and hence, none of the processes can proceed further. In this scenario, the processes are blocked indefinitely, and the system becomes unresponsive. Therefore, option D, i.e., "deadlocked" is the best choice. Option A, i.e., "spinlocked" refers to a situation where a process continuously tries to acquire a lock on a resource, leading to a wastage of CPU cycles. Option B, i.e., "stagnant," and option C, i.e., "preempted," do not accurately describe the given scenario.
