Hi teacher, can u help me answer all the question? If your answer is true I will upvote you Q1 critical section is 1. the data area which is shared by multi processes II. the code area in a process which access data shared with other processes III. a software solution to process synchronization problem IV. is the area of which only one process can enter to read shared data to ensure a proper process synchronization implementation. Select one: O AI and II only OB. I,II,III and IV OC. I, II and IV only OD. I and IV only Q2 Which of the statement(s) below is/are TRUE about the Test and Set (TS) mechanism: 1. It is used to control critical section access II. It is implemented in the instruction set level. III. it can lead towards starvation problem IV. a strength of it is that it involves polling mechanism Select one: O A IV only OB. I,II, III and IV OC I and II only OD. None O E. III and Ill only Q3 Which of the following statement(s) is(are) TRUE about file access control? 1. The access control matrix use less space in general than access control list II. Capability list use less space than access control list in general III. In the case of when file deletion is frequent, access control list is generally easier to maintain than capability list In the case of when users deletion is frequent, access control matrix is generally easier to maintain than capability list IV. Select one: AI and IV only OB. II and III only OC None of the above are TRUE. OD. I.II and III only OE L.I.III and IV only Q4 Which statement(s) about Test-and-set solution for Critical Section Problem below is(are TRUE? 1. It is deadlock-free II. It is starvation free III. It ensure processes enter CS in FIFO order IV. More than one process can enter CS at the same time without causing race condition problem. Select one: O A IV only OB. I only OC. II and I OD. I and
