In a typical desktop based operating system, execution of deadlock detection techniques at each resource request is undesirable. The two-state process model is inadequate representation of process states. Long-term scheduler executes relatively infrequently as compared to the other two medium and short-term schedulers. In dynamic memory partitioning, though compaction is beneficial but its frequent running is not desirable.

- In the context of memory management, describe in fully the differences between dynamic loading and static loading.Modern Operating Systems must tackle the challenges of Synchronization and Deadlock. ’Process Synchronization’ is the task of coordinating the execution of processes in a way that no two processes can have access to the same shared data or resource. A process requesting a resource may have to wait, if the resource is not available at that time. Sometimes, a waiting process is never able to change state, because the resources it has requested are held by other waiting processes; this situation is called ’Deadlock'.1. Concurrency in operating systems means the ability to run multiple processes or threads at the same time. (a) Can we use interrupt-disabling to implement a mutual exclusion? Justify your answer with one sentence (b) generally, what is the drawback of interrupt disabling?

- Make a distinction between dynamic loading and static loading when working with memory management.Facts: Facts about Deadlock Deadlock is a situation that occurs in OS when any process enters a waiting state because another waiting process is holding the demanded resource. Deadlock is a common problem in multi-processing where several processes share a specific type of mutually exclusive resource known as a soft lock or software. Deadlock is a situation where a process or a set of processes is blocked, waiting for some other resource that is held by some other waiting process. It is an undesirable state of the system. The following are the four conditions that must hold simultaneously (Links to an external site.) for a deadlock to occur. Mutual Exclusion –A resource can be used by only one process at a time. If another process requests for that resource then the requesting process must be delayed until the resource has been released. Hold and wait –Some processes must be holding some resources in nonshareable mode and at the same time must be waiting to acquire some more…Questions on deadlock: 1. A deadlocked state occurs whenever: A) a process is waiting for I/O to a device that does not exist B) the system has no available free resources C) every process in a set is waiting for an event that can only be caused by another process in the set D) a process is unable to release its request for a resource after use 2. One necessary condition for deadlock is held in a non-sharable mode. , which states that at least one resource must be A) hold and wait B) mutual exclusion C) circular wait D) no preemption 3. One necessary condition for deadlock is one resource and waiting to acquire additional resources. A) hold and wait B) mutual exclusion C) circular wait D) no preemption which states that a process must be holding which states that a resource can be released 4. One necessary condition for deadlock is only voluntarily by the process holding the resource. A) hold and wait B) mutual exclusion C) circular wait D) no preemption 5. One necessary condition for…
