When a deadlock occurs, all of the processes involved are stuck and unable to make progress. And because of deadlock, no process gets executed. Deadlocks can occur in a variety of situations, such as when two processes are trying to acquire locks on shared resources in different orders. These processes are said to be in a "deadlocked" state. We will learn all about the necessary condition for deadlock further in this article.Ī deadlock is a situation in an operating system where two or more processes are unable to proceed because each is waiting for one of the others to release a resource. And the process releases the resources after completing its execution and the other process will take the resources after that but this is the ideal case that does not happen generally as all the processes compete for the resources and there is a high chance that the resource that one process required is currently in use by other process and that process is not gonna leave the resources until its execution is completed and the waiting will be infinite. As we all know in a system when a process run it requires numerous resources like file, storage, CPU, input, output devices, etc. In this section, we will define deadlock in os. We will learn all about the deadlock in os from scratch in this blog. In this blog we will learn about the deadlock in operating system, first, we will define deadlock, and we will have a proper section dedicated to the question what is deadlock in os? followed by some necessary condition for deadlock with proper explanation and various methods for handling deadlock.
