A disk drive has 300 cylinders, numbered 0 to 299. The drive is currently serving a request at cylinder 51, and the previous request was at cylinder 56. The pending requests are received in the following order: 72, 56, 103, 111, 17, 189, 236, 198, and 88. Describe how the disk arm moves to satisfy all the pending requests for each of the following disk-scheduling algorithms. (Perhaps you create a diagram similar to the diagrams in Section 9.4 to support your explanation.) FCFS SSTF SCAN Calculate the total distance (in cylinders) that the disk arm moves for each of the above disk-scheduling algorithms. Compare the algorithms and explain which algorithm is the most efficient (the shortest distance) for this scenario. Write a minimum of 250 words. Part 2: Compare the algorithms and determine which is the fairest for the next process in the queue. Explain why this algorithm will always be the fairest disk-scheduling algorithm. Describe an example of circumstances where fairness would be an important goal. Describe a scenario where it would be important that the operating system be unfair. Write a minimum of 250 words.

To complete this assignment, consider the following scenario: Eight unique processes (which terminate in the following order: 21 KB, 77 KB, 199 KB, 380 KB, 489 K¬B, 212 KB, 139 KB, and 302 KB) must be placed into ten memory partitions organized in the following order: 150 KB, 275 KB, 425 KB, 300 KB, 80 KB, 117 KB, 500 K¬B, 35 KB, 313 KB, and 269 KB. Explain step by step how each of the dynamic storage allocation algorithms (first-fit, best-fit, and worst-fit) would place the given processes within the given memory partitions. Identify the memory partitions that remain after placing each process. Visually illustrate each algorithm with a chart or diagram. An example diagramPreview the document was created in Excel, but you may also choose to use a graphics editing software (PowerPoint, Paint, PhotoShop, etc.) or upload a photo of a hand-drawn sketch. Compare the algorithms and explain which model makes the most efficient use of memory and which model executes the quickest.

Using this module’s assigned readings: Examine three to five historical events which shed light on the intersection of racism and classism in 20th and 21st century American life. Please offer three to five specific examples. Examine how these events have shaped your development within the race and class spectrums.

Write a research paper about how dogs reduce stress in humans.

Explain the historical relationship between Judaism, Christianity, and Islam. What are their geographical connections? What are their historical timelines? Analyze the historical relationship between Judaism, Christianity, and Islam in order to make an argument about the similarities and differences between the three religions. Select one main example from the following list on which to focus your comparison: the nature of God, the nature of Jesus, Holy Books, or Salvation. Your analysis should span multiple paragraphs and utilize specific examples. Conclude by examining the current relationship between Judaism, Christianity, and Islam today. How has globalization influenced or affected the current relationship?

Articulate a concise problem statement around leadership, stress, and burnout. Include appropriate published or relevant primary sources to document the existence of a problem worthy of doctoral-level research. Follow these steps: Present the general issue grounded in the research literature that leads to the need for the study. Clearly describe and document the problem prompting the study. Include appropriate published or relevant primary sources to document the existence of a problem worthy of PhD doctoral-level research. Be sure to consider the following: What perspective is represented? For example, is the problem an individual-level problem, an organizational problem, an industry problem, or a social problem? Consider the theories relevant to predict, explain, and understand the problem. To identify and articulate a problem, consider the potential negative consequences to the field or stakeholders if the proposed research is never conducted. Then, create a purpose of the study by indicating the intent, goal, and rationale for researching the problem addressed in last week’s assignment. The purpose statement should begin with “The purpose of this (quantitative, qualitative, mixed) study is to…” Use the following list to create the purpose statement: Study method Study design Constructs/variables Target population Research setting Sampling frame Sampling method Sample size (Justified by scholarly sources and a power analysis for quantitative studies) Data collection method (including instrumentation) Data analysis method Software to be used for analysis A closing statement as to how the study results may inform educational theory

In James Weldon Johnson’s The Autobiography of an Ex-Coloured Man (1912) discuss and analyze those individuals and those aspects that contribute to the nameless protagonist assuming a white identity and passing for white. This ten page essay in proper MLA style must have an introduction, a body, and a conclusion with the proper aspects. This essay requires no less than eight non-fiction secondary sources and thus a Works Cited page is required.
