Assuming that a system distinguishes between four types of resources (A, B, C, and D), the following is an example of how those resources could be distributed. Identify whether the system is in safe state? If yes, what will be the sequence?
Note: This example shows the system at an instant before a new request for resources arrives.
Available system resources:
A B C D
3 3 4 3
Processes (currently allocated resources):
A B C D
P1 1 1 2 1
P2 1 0 3 3
P3 1 1 2 0
P4 3 0 4 2
Processes (maximum resources):
A B C D
P1 5 2 5 6
P2 3 1 3 3
P3 1 2 6 2
P4 5 6 5 6
