Explanation
Deadlocks occur when tasks are unable to proceed due to a circular wait for resources. The principles of deadlock include mutual exclusion, hold and wait, no preemption, and circular wait. Deadlock prevention involves designing the system to avoid deadlocks, while deadlock avoidance involves using algorithms to detect and prevent deadlocks.
