In a computer system five processes are attempting to proceed with three resource types. The total units of system resources are: (8,9,7). The maximum demands for every process are: P1(3,1,1), P2(3,3,2), P3(5,3,2), P4(5,1,2), P5(8,4,3). The current allocation is: P1 (0,1,1), P2 (2,1,1), P3 (3,1,2), P4 (1,1,1), and P5 (2,3,2). Is this state a safe state? Explain

Question 4: Write down all of the slip planes and slip directions for simple cubic (SC). How many slip systems are there? Question 5: The Burgers vector b indicates the direction and magnitude of dislocation slip in crystal structures. Said simply, the Burgers vector closes the loop when traversing an equal number of steps around a dislocation. Using a figure like shown here, graphically draw the Burgers vector around a dislocation defect in a simple cubic crystal. Question 6: Permanent...
