Consider the following snapshot of a system:
Allocation Max Available
---------- ------- ---------
A B C D A B C D A B C D
P0 0 0 1 2 0 0 1 2 1 5 2 0
P1 1 0 0 0 1 7 5 0
P2 1 3 5 4 2 3 5 6
P3 0 6 3 2 0 6 5 2
P4 0 0 1 4 0 6 5 6
Answer the following questions using the banker's algorithm.
- What is the content of the matrix Need?
- Is the system in a safe state?
- If a request from process P1 arrives for (0,4,2,0), can the request be granted immediately?
