Assessment topic: Analysis of an Operating System scenario, Computer Organisation and Architecture Report

Task Details: The report will require analysis of an operating system scenario and a report on the systems and logical issues involved, as well as options for resolving the problem and subsequent implications.

Assignment Details:

1. You are working in one company called Beautiful Process Ltd Pty. Your department is working on a new Operating System named Beaucess (Beautiful Process). Your design team needs to decide on a scheduling system for the processor that makes a minimum waiting and acceptable performance for all processes on average. They asked you as an engineer to do the below example tasks for the processor and get back to them with your suggestion.

Process / Job	Priority	Arrival Time	CPU Cycles Required / Service Time
A	3 (Silver)	0	4
B	2 (Gold)	0	8
C	1 (Diamond)	1	1
D	2 (Gold)	6	11
E	1 (Diamond)	6	3

1. Draw a timeline (Gantt-Chart) for each of the following scheduling algorithms

1. Feedback (FB) q=4
2. Highest Response Ratio Next (HRRN)
3. Round Robin (RR) (use time quantum of 4)
4. Shortest Remaining Time (SRT)
5. Shortest Process Next (SPN)

2. What is the Waiting Time and Turnaround Time of each process for each of the scheduling algorithms? (Details of the calculation is essential).

6. Feedback (FB) q=4
7. Highest Response Ratio Next (HRRN)
8. Round Robin (RR) (use time quantum of 4)
9. Shortest Remaining Time (SRT)
10. Shortest Process Next (SPN)

3. Write a report back to the head of the design department with your suggestion and reasons. (Your report should be 500 words and clearly structured)

2. Consider the directed resource graph shown below and answer the following questions:

1. Is this system deadlocked?
2. Which, if any, processes are blocked?
3. What is the resulting graph after reduction?

3. Using either internet resources or books, understand the concept of Concurrency and Mutual Exclusion. Define those terms (Concurrency and Mutual Exclusion) in your own words.

You must provide references and cite the sources that you consulted for this task. (Harvard referencing is the required method.)

4. Using either internet resources or books, understand the concept of Concurrency and Mutual Exclusion. Define those terms (Concurrency and Mutual Exclusion) in your own words.
