In a computer that supports multiprogramming, which three tasks would the memory management subsystem be mandated to perform? Explain how the following mechanisms can be used to support fault tolerance.   Virtual machines Checkpoints and Rollbacks (answer all)
Question- Provide technical reasoning for the following statements: 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.
Problem Solving: Assume the following processes are waiting to be loaded in main memory.                   Process            Size                        A                  5 MB                        B                    7 MB                       C                     8 MB                       D                     10 MB                       E                      15 MB Which of the following processes are going to be served by the main memory with 45 MB total space in a fixed partition divided into 5 slots? Currently the first slot is occupied by the operating system. Illustrate the memory allocation. What is the total free space? What is the total internal fragmentation? Still using the given process, a computer system has a 64 MB main memory which is divided into 7 fixed unequal partitions such as 10MB, 20MB, 5MB, 5MB, 8MB, 10MB, and 6MB, respectively. First partition is for OS. Illustrate the memory allocation. What is the total free space? Is there external…
Research how the separation of policy and mechanism is achieved in a virtual memory management system and why this is important in a virtual memory management system. Write up a 200 word summary of your research that outlines the responsibilities between the MMU, the page fault handler, and the external pager function and how they all cooperate together to achieve separation of policy and mechanism.
Suppose that DS=1000H, SS= 2000H, CS=3000H, ES=4000H, BP=FFH, BX=FFFFH and DI=5H.i. Which memory locations are addressed by: MOV DL, [BP]?ii. Which memory locations are addressed by: MOV EAX, [BX+DI]?
. Consider a system that has multiple processors where eachprocessor has its own cache, but main memory is shared among allprocessors.1. a) Which cache write policy would you use?2. b) The cache coherency problem. With regard to the systemjust described, what problems are caused if a processor has acopy of memory block A in its cache and a second processor,also having a copy of A in its cache, then updates mainmemory block A? Can you think of a way (perhaps morethan one) of preventing this situation, or lessening itseffects?

1.Which of the following causes file reads to slow down? a)Excessive long-term hard disk use b)Cache files on disk c)File fragmentation d)Experienced mechanical head 2.The primary reason why interruptions are often left enabled during interrupt handling is because: * a)Not all CPU architectures support it. b)Because interrupt disabling is sometimes not an atomic action. c)To enable the handling of interrupts from many devices by a single interrupt handler. d)Preemptive interrupt management is required for increased system responsiveness.
Questions 1. If you are to add a new 10MB process in the memory, where could it possibly be added and why? 2. What could be the size of the free block just before it was partitioned by X? Rationalize your answer. 3. Would you suggest the provisioning of virtual memory in this configuration? Why or why not? 4. Is it possible to add a new 7MB process using the first-fit placement algorithm without swapping out any process? Why or why not? 5. A new process is requesting a 3MB allocation. Illustrate the possible memory configuration using a horizontal segmented memory strip (like the diagram above), where a partition will be created for the new process under the following placement algorithms: best-fit and first-fit. Label your illustration clearly.
