A resource, such as a CPU or tape transport, that is not rendered useless by being used. Magnetic disks or tapes can be used often indefinitely and are to be regarded as reusable resources.

What is drawback of Banker's algorithm?
Disadvantages of the Banker's Algorithm
It requires the number of processes to be fixed; no additional processes can start while it is executing. It requires that the number of resources remain fixed; no resource may go down for any reason without the possibility of deadlock occurring.
Which of the following is a condition that causes deadlock Mcq?
A process must be holding at least one resource and waiting to acquire additional resources that are currently being held by other processes. This condition for deadlock is refered to as : Mutual exclusion.
What will happen when a process terminates?
Explanation: When a process terminates, it removes from all queues. All allocated resources to that particular process are deallocated and all those resources are returned back to OS. 4.
Which of the following is not an operating system?
Android is not a operating system.
How does Banker's algorithm prevent deadlock?
The banker's algorithm is a resource allocation and deadlock avoidance algorithm that tests for safety by simulating the allocation for predetermined maximum possible amounts of all resources, then makes an “s-state” check to test for possible activities, before deciding whether allocation should be allowed to continue ...
Why do we use bankers algorithm?
Banker's Algorithm is used majorly in the banking system to avoid deadlock. It helps you to identify whether a loan will be given or not. This algorithm is used to test for safely simulating the allocation for determining the maximum amount available for all resources.
Which of following is not a condition of dead lock?
answer is b. without reentry the system will not be in deadlock. it will be just not be able to do usefull work.
Which one of the following can not be scheduled by the kernel?
(A) User level threads are not scheduled by the kernel. ... (B) When a user level thread is blocked, all other threads of its process are blocked.
What will happen if a non recursive mutex is locked more than once?
What happens if a non-recursive mutex is locked more than once. Deadlock. If a thread that had already locked a mutex, tries to lock the mutex again, it will enter into the waiting list of that mutex, which results in a deadlock.
What type of scheduling is round robin scheduling *?
Round Robin is a CPU scheduling algorithm where each process is assigned a fixed time slot in a cyclic way. It is simple, easy to implement, and starvation-free as all processes get fair share of CPU. One of the most commonly used technique in CPU scheduling as a core.
What type of scheduling is round robin scheduling?
Round Robin is the preemptive process scheduling algorithm. Each process is provided a fix time to execute, it is called a quantum. Once a process is executed for a given time period, it is preempted and other process executes for a given time period. Context switching is used to save states of preempted processes.
Which one of the following is not a popular desktop operating system?
Which of the following is not a popular desktop operating system? Exp: Mountain Lion is not a popular desktop operating system. 32.
