Please answer all the questions with details (questions 4, 5 and 6)

A program consists of 3 concurrent processes P0, P1 and P2 along with 3 binary semaphores. The semaphores S0,S1 and S2 are initialised as 1,0 and 0 , respectively. What is the minimum number of times P0 will print ' 0 '? Question 5[6+6=12%] There are three Processes P1, P2 and P3 sharing mailbox A. Process P1 sends a message to mailbox A, while P2 and P3 execute a receive () command from mailbox A. a) State three methods that could be used for deciding which process receives the message first. b) What is the issue with a mailbox being owned by a process as opposed to the operating system? Question 6[23=6%] To which physical address (in binary format) does the logical address 0011011010101010 correspond, under the following hypothetical memory management schemes? Justify your answers. a) A paging system with a page table containing 512 entries and in which the frame number happens to be two times larger than the page number. b) A segmentation system with a maximum segment size of 2,048 bytes, using a segment table in which bases happen to be regularly placed at real addresses equal to 22+4,096+ segment number
