One feature that separates Linux from other operating systems is that the source code, along with any changes, remains public. Closed source operating systems, where developers refuse to share some or all of the code, may hinder third-party software developers who create programs and apps for the operating system.
Supporters of open source maintain that open source software enables developers to examine, correct and enhance code to create better programs. Communities of open source programmers can make changes immediately, which they claim results in higher-quality software. For example, proponents of open source software use Linus, which is known for its speed and stability. Of the 500 fastest supercomputers, 90 percent use variants of Linus. Companies and nonprofit organizations can distribute and sell their versions of Linus. This enables those without the expertise to modify open source software to benefit from the creative efforts of the Linux community.
Fear of viruses and other security concerns can lead some to question about whether open source software is worthwhile. Dishonest and antonymous developers can use open source software to create programs, that may be malware. Proponents of closed source software also argue that companies and developers should be able to control and profit from operating systems they create.
Are the security concerns about open source software legitimate? Why or why not? What might be some of the advantages and disadvantages of open source versus closed source operating systems? Does the open source model lead to higher-quality software? Why or why not?

Chip makers (Qualcomm and Intel, for instance) and Smart Phone manufacturers (Apple and Samsung, for instance) belong to two oligopoly markets. However, these markets are connected because smart phones cannot work without chips. In 2017 we have seen a complex battle over patents and how much license fees should be between Apple and Qualcomm, the largest players in each market. They were fighting with lawsuits in the US, UK and China. Apple ended the litigation with Qualcomm in 2019 and agreed to buy Qualcomm Snapdragon chips because Intel-Apple were not able to develop 5G chips, Samsung and Wawei already have it, and Apple found itself cornered without 5G chips. However, the discussion of licence fee models is still relevant. Read this Reuters' article from 2017 about the license fee model supported by Qualcomm, Nokia and Ericsson, and the license fee model that Apple, Google, Mercedes, and VW would like to have: https://www.reuters.com/article/legal-uk-eu-technology-patents/apple-faces-down-qualcomm-ericsson-over-eu-patent-fees-idUSKCN1C71EO
1. Show with an example how these two license fee models are different.
2. As a consumer of final products and not chips, what model favors you? Why?

First, let's compute your monthly (don't forget to modify your interest rate, for monthly compounding!!) debt of the student loan. Your payments will start on September 2022 and nish on September 2032. Please compute your monthly payment (using the assumptions or your real data [amount loaned, interest rate and duration]) and the total interest you will pay.
2. Compute the monthly payment of your house and the total interest you will pay on it. You have until 2025 to get the money for the down payment and you will start paying your mortgage on September 2025 and continue until September 2055. Compute the total interest you will pay.

For the last few years, many property developers have been experiencing sluggish sales in the high end property market due to various factors. Use the Attitude-Toward-Object Model to suggest how a property developer can change consumers’ attitudes in favor of their products by:
(a) add an attribute that previously was ignored or an improvement or innovation; or removing a product feature
(b) change perceived importance of an attribute
(c) develop new products
(Note: to answer this question, students are expected to research the Malaysian property market. Use your creativity and research from other countries’ trends to suggest adding new attribute, change perceived importance of attribute and new product development.)

Metrics This should be a review of several key metrics that the team will use to assess progress in achieving its vision for the proposed business model innovation (the “to be” business model). What metrics will be most impacted? What would success look like? What types of metric feedback would be sufficient for recognizing failure? What rough-range sales/market share projections might be possible under best case scenarios / average estimates / worst case scenarios? Use ranges, but be aim for plausible specificity. Ground your metrics and numbers in some supportable data/reality. You should be able to meaningfully explain if the risk is worth it for this size of a potential return.
