In the context of concurrency control, a given pair of operations in a schedule is called conflict schedule if(A) At least one of the operations is write operation(B) Both the operations are performed on the same data item(C) Both the operations are performed by different transactions(D) Both the operations are performed on different data itemsChoose the correct answer from the options given below:
Consider a computer system with multiple shared resource types, with one instance per resource type. Each instance can be owned by only one process at a time. Owning and freeing of resources are done by holding a global lock (L). The following scheme is used to own a resource instance:function OWNRESOURCES(Resource R)Acquire lock L / / a global lockif R is available thenAcquire RRelease lock Lelseif R is owned by another process P thenTerminate P, after releasing all resources owned by PAcquire RRestart PRelease lock Lend ifend ifend functionWhich of the following choice(s) about the above scheme is/are correct?

Choose two statements in context of monitor based synchronization scheme that use condition type variable x:I: Only wait () and signal () operations can be involved on X.II: If process p invokes X, wait() operation; then P is suspended until another process invokes X, signal().III: The X, signal() operation resumes exactly one suspended process and if no process is suspended, the it has no effect.
Consider the following pseudocode, where S is a semaphore intialized to 5 in line#2 an counter is a shared variable intialized to 0 in line#1. Assume that the increment operation in line#7 is not atomic.1. int counter = 0;2. Semaphore S = init(5);3. void parop(void)4. {5. wait (S);6. wait (S);7. counter++;8. signal (S);9. signal (S);10. }If five threads execute the function parop concurrently, which of the following program behavior (s) is/are possible?
