For a deadlock to arise, which of the following conditions must hold simultaneously ? a. Mutual exclusion b. No preemption c. Hold and wait d. All of the mentionedSuppose Alice has r and w rights over the file book. Alice wants to copy r rights to book to Bob. a.Assuming there is a copy right c, write a command to do this. b.Now assume the system supports a copy flag; for example, the right r with the copy flag would be written as rc. In this case, write a command to do the copy. c.In the previous part, what happens if the copy flag is not copied? Note:Follow the concept of access control matrix and do not use commands like chmod.
- What is the difference between a binary semaphore and a counting semaphore? Question 9 options: A binary semaphore is used for mutual exclusion, while a counting semaphore is used for synchronization. A binary semaphore can only take two values, while a counting semaphore can take any positive integer value. There is no difference between a binary semaphore and a counting semaphore. A binary semaphore is used for synchronization, while a counting semaphore is used for mutual exclusion.Software caching. Since the default implementation of contains() calls get(),the inner loop of FrequencyCounterif (!st.contains(word)) st.put(word, 1);else st.put(word, st.get(word) + 1);leads to two or three searches for the same key. To enable clear client code like thiswithout sacrificing efficiency, we can use a technique known as software caching, wherewe save the location of the most recently accessed key in an instance variable. ModifySequentialSearchST and BinarySearchST to take advantage of this idea.Which of the following is true on Deadlock detection a. Must know the maximum need of resources b. Can avoid the deadlock c. Does not need to know the maximum need of resources d. None of the above
