Scheduling Models

Description

Prior to beginning work on this assignment, read the following sections in your textbook: 9.1 to 9.6 and 9.9 in Chapter 9: Mass-Storage Structure. Finally, read the Operating System – Scheduling Algorithms tutorial (Links to an external site.).

Part 1:
To complete this assignment, consider the following scenario:

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.

Metabolic Syndrome

Choose a current contemporary health issue (approved by the professor) to investigate and become an expert. Students need to incorporate a detailed explanation of the topic, in addition to, examining current research being conducted in the field from primary articles. Further details on project requirements are outlined in Class Project Part II. The content of the project will be contracted with the professor. Students must declare his/her intention by completing the attached contract and submitting it by the assigned deadline. Some examples of how this may be accomplished are:

  • Submit a PowerPoint presentation.
  • Video a documentary on the health topic.
  • Develop a webpage on a health issue with the use of credible references.

Sample Presentation Topics

Environmental Ethics

Description

Environmental Ethics Position Paragraph

Your task is to write a paragraph (maximum length of one page double spaced) that analyzes one of the following environmental ethical issue. You choose which issue to write about; in this assignment, reflect deeply on a topic that matters to you. You must argue your position with ethical theory and also show how your position is stronger than the opposing position supported by another theory.

Option A:

Should animals be used in medical research? In your response, consider which kind of animals (if any) would be morally permissible to use in medical research and what consideration should be given regarding pain.

Option B:

Is a vegetarian diet more ethical than a non-vegetarian diet? In your answer, consider the issue of animal rights and the environmental impact of both meat and plant-based diets.

Option C:

Consider the use of Genetically Modified Organisms (GMOs). Is the use of GMOs in food production ethical? In your answer, consider both health and environmental concerns.

You must apply at least one ethical theory to support your position and explain how a different theory compares when applied to this issue.You must also show how your position supported by ethical theory is stronger than another position supported by another theory.

It is not enough to name a theory; you must explain the theory and demonstrate how your position reflects the logic and reasoning of that theory.

Remember that theory is the �why� behind your beliefs.
