b) Modern operating systems support multithreading, and many modern applications are multithreaded (i) There are several differences between processes and threads. Describe THREE (3) of them. (3 marks) (ii) Consider implementing a spreadsheet application similar to Microsoft Excel or LibreOffice Calc. Would you implement it to be a single-threaded, a multi-threaded, or a multi-process application? Support your choice with THREE (3) good reasons or benefits of your choice. (3 marks) (iii) Parallelism and concurrency are related but are also different. Elaborate these TWO (2) terms. (2 marks) (iv) There are a few ways to establish the relationship between user threads and the kernel threads. Which model is most commonly implemented, and what is the main feature of this model? Name ONE (1) operating system that implements this model. (2 marks)
