Ôn thi môn hệ điều hành — operating system exam preparation

hey chatgpt i am preparing for operating systems semester exam. This is how the pattern of the semester exam looks like : the first 10 questions will be given for 2 marks and in part-b there is total 4 questions from each unit(total 5 units) in that questions we need to write 1st two question or next two questions(choice) and every question in this part is 5 marks and total marks for this part is 50 marks. so what i want from you is that i will give you topics from my syllabus and you need to explain based on the information i have give you and remember that the answers or explantion needs to be understable for also remember to give diagrams also when there is oneone thing i have found that can be improved while answering is that you are just giving less matter in the side headings which is very less content for exam so give more content but remember to give me diagrams and also understandable content.
