Fundamentals of Operating Systems and Java Programming

- Operating Systems and UML Use Cases

Purpose of the assessment (with ULO Mapping) Main objectives of this assignment is to enable student to analyse the two case studies, gather requirements for OS and the installations. After successful completion of this assignment, students should be able to:

a. Analyse and Discuss the significance of use cases of UML specification.
b. Install/upgrade OSs for the business, information, technology, and application domains.

Assignment 1 Specification

Business case studies:You are required to answer all two case studies.

Case study 1: UML Use cases

In a banking system, use cases define the interaction that takes place between customers and automated teller machines (ATM). Given figure shows an example use case diagram for an ATM subsystem. The Customeractor represents the classof all customers who will use the ATM subsystem. When you use the local ATM to withdraw cash, you are an instance of Customer using a particular instance of the use case Withdraw cash. The person standing on the line behind you is another instance of Customer, who will use the different instance of the use case Withdraw cash. Someone else may use the instance of use case Check balance orPrint mini-statement. You may successfully withdraw cash from the machine, but the person behind you may find that he or she does not have enough money deposited, and the use case instance will proceed a different course from yours, rejecting the request.

Note - The term scenariosis used to refer to the different possible courses that different instances of the same use case might take.

Q1. List at least three scenarios that are common to the given use cases.

Q2. List the possible scenarios for all the use cases (other than the ones given in Q1.)

Q3. Specify any other use cases possible for ATM system.

Case study 2:

Microsoft described Windows 10 as an 'operating system as a service' that would receive ongoing updates to its features and functionality, augmented with the ability for enterprise environments to receive non-critical updates at a slower pace, or use long-term support milestones that will only receive critical updates, such as security patches, over their five-year lifespan of mainstream support. Terry Myerson, executive vice president of Microsoft's Windows and Devices Group, argued that the goal of this model was to reduce fragmentation across the Windows platform, as Microsoft aimed to have Windows 10 installed on at least one billion devices in the two to three years following its release.

Write a report on Windows 10 and answer the following questions in your own words

- Give a brief history about Windows systems.

- What are the minimum system/hardware requirements for Windows 10?

- How to install/upgrade to the new Windows 10? And specify the configuration tasks performed following the installation.

- What security features can be highlighted in the system?

- Compared to other desktop operating systems, what are the advantages of Windows 10?

- What are the criticisms about Windows 10?

In your report, you must provide operation examples to demonstrate your understanding of Windows 10. Your report should be around three pages long and supplemented with diagrams and tables, if appropriate.

Write a report with the following contents:

- Introduction
- Case study 1 (UML use cases)
- Case study 2 (Operating Systems - Windows 10)
- Conclusion

I was good in preparing my assignments, but the principle issue which dependably stayed with me was the sequence. At that point fortunately, I found Expertsmind.com and now I just get most elevated results as well as I present my assignments before the due date. Thus, I want to prescribe Assignment Help to everyone. Thanks
