Question
Consider a system with a total of 150 units of memory, allocated to three processes as shown:
Process
1
2
3
Max
70
60
60
Hold
45
40
15
Apply the banker's algorithm to determine whether it would be safe to grant each of the following
requests. If yes, indicate a sequence of terminations that could be guaranteed possible. If no, show
the reduction of the resulting allocation table.
1. A fourth process arrives, with a maximum memory need of 60 and an initial need of 25 units.
2. A fourth process arrives, with a maximum memory need of 60 and an initial need of 35 units.
