5. Consider the following snapshot of a system: Allocation Max Available ABCDABC DABCD PO 3 0 1 1 4 1 1 1 1 0 20 P10 10 0 0 212 P2 1 11 0 4210 P3 1 1 0 1 1 1 1 1 P40 000 2120 Answer the following questions using the banker's algorithm: a) What is the content of the matrix Need? Show your work. b) Is the system in a safe state? Remember that you must find a safe sequence in order to answer this question. Show your work. c) If a request from process P4 arrives for 0,0,2,0), can the request be granted immediately? Show your work. Note that you must apply the whole Banker's algorithm here.
