For example, in a multi-threaded application, a critical section of code may be protected by a lock that can only be held by one thread at a time. This means that once a process acquires a resource, other processes are denied access until it is released. The mutual exclusion condition states that some resources can only be accessed by one process at a time. Let's explore each of these conditions in detail: Mutual Exclusion Necessary Conditions for Deadlock in OSĭeadlocks occur due to the fulfillment of four necessary conditions for deadlock in operating system known as the Coffman conditions.

The result is a deadlock cycle, where the processes are stuck in a circular dependency, waiting indefinitely for the resources they need to continue.ĭeadlocks can have severe consequences, leading to system crashes, frozen applications, and unresponsive user interfaces. This occurs when a process requests a resource held by another process, which is waiting for a resource held by the first process. In a deadlock, each process is stuck in a waiting state, unable to proceed with its execution. Deadlocks can occur in various systems, including computer networks, distributed systems, and multi-threaded applications.
This situation creates a standstill where no progress can be made until the deadlock is resolved. Advantages and Disadvantages of Deadlockĭeadlock is a scenario in operating systems where two or more processes are unable to proceed because each process is waiting for a resource that is being held by another process.Difference Between Deadlock and Starvation.In this article, we will explain deadlock in operating systems, explore the causes and characteristics of deadlock in OS example, and discuss various strategies for handling deadlocks in OS and preventing deadlocks in operating systems. What is deadlock in operating system? Deadlock is a critical issue that can occur in operating systems when multiple processes cannot proceed because each process is waiting for a resource that is being held by another process.
