Question
Laboratory Exercise Memory Management Objectives: At the end of the exercise, the students should be able to: • Examine some techniques in memory partitioning; and • Analyze the underlying concepts and implications of virtual memory. PartI Instructions: Read the description of the memory configuration and analyze the given diagram. Then, answer the following questions. Memory Configuration: A computer implements a dynamic partitioning technique for memory management. A number of allocation and swapping-out operations have been caried out while the computer is up and running. The disgram below shows the computer's current memory configuration/allocation. The addresses go from left to right. The gray areas represent blocks that are occupied by running processes, while the white areas indicate free memory blocks. The last process that was loaded into the memory is marked with a red X in the diagram, and its size is 2MB. On ly one process was swapped out afterthat. 4MB 1MB SMB 8MB 2MB 4MB 3MB X Questions 1. If you are to add a new 10MB process in the memory, where could it possibly be added sand 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. Isit possible to add a new 7 MB process using the first-fit place ment algorith m without swapping out any process? Why or why not? 5. A new process is requesting a 3MB a llocation. Illustrate the possible memory configuration using a horizontal segmented memory strip (like the disgram above), where a partition will be created forthe new process underthe follo wing placement algorithms: best-fit and first-fit. Label your illustration clearly.

Part II Instructions: 1. Explain the operation and management of the following virtual memory. Search for relevant studies and literatures that would support your answer. Properly cite your references. • Linux Virtual Memory Windows Virtual Memory 2. Then, answer the following items based on your research. a. Between the operation and management of Linux and Windows virtual memory, which do you think is less complex and why? b. Were you able to find similarities between Linux and Windows virtual memory? o If your answeris yes, explain each similarity. o If your answer is no, explain the possible reason why there is no similarity. c. What are the possible drawbacks of not implementing virtual memory? d. If you are to design a memory management system, wouldyou incorporate virtual memory into your design? Why or why not?
