![]() It occurs due to the uncontrolled priority and resource management.Ī resource can only be shared in mutually exclusive manner. The requested resource is continuously be used by the higher priority processes.ĭeadlock happens when Mutual exclusion, hold and wait, No preemption and circular wait occurs simultaneously. The requested resource is blocked by the other process. Starvation is a long waiting but not infinite. Starvation is a situation where the low priority process got blocked and the high priority processes proceed. Difference between Starvation and Deadlock Sr.ĭeadlock is a situation where no process got blocked and no process proceeds The computer becomes unresponsive since all the processes got blocked. None of the process is progressing and they are all waiting. In this scenario, a cycle is being formed among the three processes. P3 also demands for R1 which is being used by P1 therefore P3 also stops its execution. P2 also stops its execution because it can't continue without R3. P2 also demands for R3 which is being used by P3. P1 halts its execution since it can't complete without R2. R1 is assigned to P1, R2 is assigned to P2 and R3 is assigned to P3.Īfter some time, P1 demands for R1 which is being used by P2. There are three different resources R1, R2 and R3. Let us assume that there are three processes P1, P2 and P3. In this situation, none of the process gets executed since the resource it needs, is held by some other process which is also waiting for some other resource to be released. The process uses it and release on the completion.Ī Deadlock is a situation where each of the computer process waits for a resource which is being assigned to some another process.OS grant the resource if it is available otherwise let the process waits.The process requests for some resource.However, the resource is granted in a sequential order. 17(4), 6–15 (1983).Next → ← prev What is Deadlock in Operating System (OS)?Įvery process needs some resources to complete its execution.
