Research, Collaboration and Academic Integrity
There is a research component to this assignment: any direct references, figures, or quotes used must be cited, and a bibliography should be included as an appendix at the end of your report.计算机系统作业代写
We will not accept citations from any encyclopedic resource; e.g. Encyclopedia Britannica, Encarta, World Book, Wikipedia (or syndication thereof), and so on.
You may share and discuss any links and references you find relevant to completing this assignment on the discussion forums, so long as you include how you found the resource that you mention.
You are free to refer to textbooks, notes, work in study groups etc. to discover approaches to problems; however the assignment should be your own individual work.
Do not ever simply copy and paste what another writer has written.
This is stealing. What we need is your own words — your own understanding. If you try to represent someone else’s work as your own it will be dealt with severely. Instead, we want you to paraphrase what others have said — to put the concepts they have discussed into your own words.计算机系统作业代写
When preparing a report such as this it is almost impossible to prepare an accurate report without referring to some resources for assistance to complete the tasks. For this reason, we ask you to reference from where you get your information.
We require these references to be formally correct according to one of the standard styles used in research. For example, either the APA or Harvard styles would be acceptable. See the RMIT library reference guides (http://www.rmit.edu.au/ browse;ID=8rwjnkcmfoeez) for further details.
Let us say that I want to use the ideas in the following paragraph to explain bit depth as it relates to images:
Bit depth refers to the colour information stored in an image. The higher the bit depth of an image, the more colours it can store. The simplest image, a 1-bit image, can only show two colours, black and white. That is because the 1 bit can only store one of two values, 0 (white) and 1 (black). An 8-bit image can store 256 possible colours, while a 24-bit image can display about 16 million colours.计算机系统作业代写
The above paragraph was taken from http://etc.usf.edu/techease/win/images/what- is-bit-depth/.
The first step might be to paraphrase the information about — that is to put the information above into your own words, such as:
Bit depth signifies how many colours that can be represented in an image – the more bits per pixel the wider the range of colours (Techease, 2015)
This would then be cited in your reference list as:
Techease, 2015, “What is bit depth?”, Retrieved from http://etc.usf.edu/ techease/win/images/what-is-bit-depth/ at 7 pm on Saturday 8th March 2015.
You would reference this citation similarly in the bibliography.
Please note that we require you to have both a reference list and a bibliography. The difference between these two resources is that the bibliography lists all documents that you have read that have contributed to your submission whereas the reference list only lists those documents you have actually cited in the text of your report.计算机系统作业代写
Also, with the exception of very short quotes (less than a line) we require you to put the content in your own words — we are assessing you on your understanding of the course content, after all. If you quote directly from a source, please ensure that the quote is within “talking marks” such as the ones I have just used. Whether you quote directly from a source or paraphrase the source (as I have done above) you still need to cite the source and ensure the source is included in the reference list and bibliography.
Submissions
Before you submit anything, please read through the assignment specifications again carefully. Check that you have followed all instructions. Also check that you have attempted all parts of all questions.计算机系统作业代写
Prepare the answers to this assignment in an electronic format, and convert to a single Acrobat PDF (.pdf) file for submission. Paper submissions are NOT accepted; if some parts of the assignment have been completed by hand, scan these in and include this in your electronic submission.

Question 2 — Process Architecture (4 + 4 + 2 + 2 + 2 = 14 marks)
Mobile phones are being used as computers by more people and for more purposes in the modern world. A mobile phone has CPU, GPU, and other chipsets for telecommunication, GPS, memory, input/output wireless or wired. What’s more, a specific operating system has been designed for mobile devices. New products are launched every year. All the vendors claim that the performance of their products have been improved with benchmark.
(4 marks) Please select four models of mobile phone with different configuration specified as follows,
- Model A: Dual-core 32-bitCPU
- Model B: Dual-core 64-bitCPU
- Model C: Quad-core 64-bitCPU
- Model D: Octa-core 64-bitCPU
and (4 marks) Benchmark for each model need to be compared to answer the following question:
a.(2 marks) What does 32-bit and 64-bitMean?计算机系统作业代写
b.(2 marks) What difference does 32-bit and 64-bit make in regard to processor, RAM, andApps?
c.(2 marks) How does the number of cores improve the mobiles performance? Do you think the performance increaseslinearly?
Marks will be awarded based on how convincing the argument is and the use of relevant benchmark data.
Question 3 — Building a Recommended Platform Machine (36 marks) 计算机系统作业代写
System Categories Description
If you’re going to build a computer from scratch for a specific purpose, you’ll want to keep that purpose in mind when choosing your components; don’t just go to the store or an online shop and start buying.计算机系统作业代写
Different configurations suit different purposes. The cost implications of choosing between these uses are huge. A cheap work computer might cost only two or three hundred dollars. A server can reach tens of thousands of dollars.
This task will have your sourcing parts for two different computer systems. Spend no more than is required for your usage.
Here are some general system categories:
- Office computer (Basic System) — An office computer can be expected to do word processing, spreadsheet and database work, network access, e-mail and a little light development of spreadsheets, database, and计算机系统作业代写
- Gaming computer (A Gamer’s Rig) — Playing the latest video games places heavy demands on a computer, both in terms of graphics and processor performance. To ensure you have the best platform for your digital adventures you’ll need a machine that has a powerful graphics processing unit, fast internal storage, and a display that can keep up with everything that is going on in the game.
- Hometheatre PC (Video Editing Suite) — A desktop PC for playing HD movies, streaming HD videos, and doing lots of video You need a graphics card good enough at rendering what you need done. Your machine needs to support multithreaded codecs. A large hard drive will be needed.计算机系统作业代写
- Database server (Server System) — A computer is going to be performing complex tasks (such as using the PHP programming language, database storage, and database retrieval). It holds the database management system and the databases. Upon requests from the client machines, it searches the database for selected records and passes back the results. It needs multiple CPUs, as much RAM as possible, and massive
The parts should be chosen for being affordable, economic, without over spec based on the purpose described above. Network device (router, cable, firewall) and network access (internet and intranet) are not in the scope of this assignment and the assumption is you have them set up already.
Select two categories using the last digit (d) of your RMIT student number:
| d | Categories to select |
| 4 or 7 | Gaming computer and Database server |
| 8 or 6 | Gaming computer and Home theatre PC |
| 2 or 5 | Office computer and Home theatre PC |
| 3 or 9 | Office computer and Database server |
| 0 | Home theatre PC and Database server |
| 1 | Office computer and Gaming computer |
