![]() So, it is said that no two processes can be executed simultaneously. Only one process can be scheduled at a point in time. Hold and waitĪs the name suggests, this deadlock condition in OS requires a process to wait for an occupied resource. Henceforth, no two processes can ask for the same resource. Mutually exclusive means that for every process, there is a designated resource that cannot be shared. ![]() This is because a deadlock is earmarked by four conditions that are to be fulfilled anyhow. It isn’t necessary that a deadlock will happen whenever more than one process, along with more than one resource, is involved. So, this was a deadlock example resulting in a potential deadlock in the operating system. Subsequently, neither Process 1 nor Process 2 gets executed because the resources needed by them are held up. Process 2 needs “Resource 2” and waits for “Resource 1”.Process 1 is assigned to “Resource 1” but ends up waiting for “Resource 2”.In the same vein, Resource 1 and Resource 2 are two resources. Let’s assume that Process 1 and Process 2 are two processes. Let’s understand what deadlock is in the operating system better with this example. A deadlock in OS makes it circle the drain since no process is executed. It happens when a resource is being held up or occupied at the moment because some other processes are running in the background. When more than one process taking place in a system is prevented from getting executed, it is called a deadlock. Later, if you wish to learn more about deadlocks, you can do so with our lucrative Full-Stack Developer Bootcamp online. In this blog, we will analyze in detail what deadlock is in OS, get a clear picture with a deadlock example in OS, methods of dealing with it, and much more. ![]() This competition gets culminated in what tech experts have termed the deadlock in OS. But when multiple processes start running simultaneously on a system, chances are that each of these processes has to compete for a resource. And as soon as the process ends, the in-use resource is duly released. The resource could be in the form of the system’s CPU or some plugged-in device such as the standard input or output device. It is well-known that every process that is taking place on a system needs the assistance of some resource to get executed.
