1. Consider a system with ten resources and four processes competing for them Let process P1 have a maximum need of seven resources, process P2 have a maximum need of five resources, process P3 have a maximum need of eight resources and process P4 have a maximum need of six resources Let [al, a2, a3, a4] represent the allocation vector with respect to the resources currently allocated to the processes P1 through P4, in that order. The system is deemed to be in a safe state with respect to an allocation vector if there is a possibility of allocating the remaining resources in such a way as to satisfy the maximum needs of all the processes Examine each of the following allocation vectors and determine if it is safe or not. Identify the one that is NOT safe? b) [3,2,0,3] d) [2,3,2,0]
