Deadlocks pose significant challenges in modern operating systems, potentially leading to system-wide halts and decreased reliability. This review paper explores the various aspects of deadlocks, including their causes, detection methods, prevention strategies, and recovery techniques. First, the paper examines the fundamental conditions necessary for deadlock occurrence, namely mutual exclusion, hold and wait, no preemption, and circular wait. Understanding these conditions is crucial for devising effective deadlock management strategies. Next, it delves into deadlock detection methods, highlighting approaches such as resource allocation graphs and deadlock detection algorithms. These methods allow the operating system to periodically assess the system state and identify potential deadlocks before they escalate.The review further discusses deadlock prevention techniques, which aim to structurally eliminate one or more of the necessary deadlock conditions. Examples include enforcing a policy of no preemption or imposing constraints on resource allocation to prevent circular wait scenarios.
