Written 5: Safe Wombat Storage (25 Marks)

Alternative Partial Credit Problem: For part marks, you can instead solve the following multithreading problem: write psuedocode to find if a file with a specific name exists in a two-level directory. Your answer should use at least two threads and should use the level of complexity of multithreading described in the course. You may assume the specific data structures.

Full Mark Problem: After a considerable emotional and monetary investment, I have developed an IO device that allows users to input an image, remove all non-wombat aspects of the image, store it on the device for future access, then later retrieve it for the user.

For the custom OS that uses this device, there are two commands for IO: iowrite(device_id, device_register, input) and ioread(device_id, device_register, variable_to_read). This device has the unique id "Wmbt" that allows for the OS to communicate with it.

a 2 marks) Describe what type of device is this based on course terminology. (Suggested Length: 4-5 words.) For a hint, I am thinking of terminology like "sharable"

Written 4: Driving Forward (15 marks)

Modern cars have a custom Operating System that manages a car's systems. For example, a touch screen may manage what profile is active, with specific settings for mirrors or seat height based on the user's settings, while another system may manage analytics on the car, such as readings on the engine temperature and efficiency. In fact, devices may interface with other devices automatically, such as bluetooth connections to phones to broadcast music or even receive instructions to turn on the car's heater to help remove snow.

1 mark 4.a) What type of environment is this OS? Suggested Length: 1-2 words.

5 marks 4.b) A car company wants to add a customized cache to this Smart Car OS hardware that allows for faster read/write access of small data structures (less than 4 kilobytes). What data structure from either Unit 5 or 6 would you suggest to be stored in this cache? Why? Suggested Length 2-5 sentences.

4 marks 4.c) The marketing department wants to add more wireless adapters (e.g., bluetooth) and usb connection ports. What are the advantage/disadvantages of these additions? Suggested Length 3-5 sentences. Reminder: This is a class on a certain topic

5 marks 4.d) Suppose they want to add a local file system to record each profile's logs to their car (for insurance purposes of tracking speed and other information). What are the advantage/disadvantages of these additions especially in terms of unit 2 and 3 concepts? Suggested Length 3-5 sentences.

Written 3: Myriad of Memory Management Matters (25 marks)

Let's see if you remember Unit 5 material...

4 marks a) Define paging and virtual memory in a way that computing science students that didn't take this course could understand. Suggested Length: 2-4 sentences. Note that there is an emphasis on avoiding too complex descriptions or course terminology.

Written 2: Oh the Humane-AI-ty! (15 marks)

Your Mission: Pick exactly one prompt and respond to it: 

Prompt 1: Wearable devices, such as the much maligned [word meaning "made fun of"] Humane AI (https://www.wired.com/review/humane-ai-pin/) tool from last year, integrate with Machine Learning to handle tasks such identifying objects in a room from video or informing users about directions to specific landmarks given audio. If you were to design such a device's OS, how would you  consider synchronization,  multithreading,  paging,  virtual memory, and  IO management in its design? Suggested Length 1-2 paragraphs.

Prompt 2: Agree/Disagree: Operating systems, through synchronization, multithreading, paging, virtual memory, and IO management, have improved society's ability to deal with British Columbia's flooding and other natural disasters.

Grading Criteria for Either Prompt: Writing quality, demonstrating knowledge of OS (e.g., it is clear from terminology used that you understand these topics), and a demonstrated nuance (or good insight) in comparing/contrasting the systems. Your answer should cover at least three of the mentioned topics. You are welcome to perform research on the topic but it isn't necessary.

Written 1: Spreading RAM this Holiday Season (9 Marks).

A major driver of modern society is supply chain management. For example, factories produce RAM from raw materials that is then distributed to different stores, companies, and needy students. List each unit in the course, give a 1 sentence description (or title) of the unit, and explain how each unit can improve or relate to computer part supply chain management in 1-2 sentences.

Marking Criteria: Correctness and linking to each of the main units. Note that you should talk about how the unit helps solve the problems whether in terms of actual solutions or hypothetically (e.g., if we apply method X to problem Y it can help with Z).
