Question

A system with 5 processes P0 through P4 and three resource types A, B, C has A with 10 instances, B with 5 instances, and C with 7 instances. At time t0, the following snapshot has been taken:

Process:
P0
P1
P2
P3
P4
Allocation (process-wise: P0 through P4 from top to bottom):
A B C
0 1 0
2 0 0
3 0 2
2 1 1
0 0 2
Max (process-wise: P0 through P4 from top to bottom):
A B C
7 5 3
3 2 2
9 0 2
2 2 2
4 3 3
Available:
A B C
3 3 2
The sequence leads the system to:

a) An unsafe state
b) A safe state
c) A protected state
d) a deadlock

Answer 1

The system is in a safe state.

Step-by-step explanation:

The given information represents the current state of a system with 5 processes (P0 through P4) and three resource types (A, B, C) along with their allocation and maximum values. To determine if the system is in a safe or unsafe state, we need to check if there is a possibility of the system entering a deadlock.

Based on the provided information, the system is in a safe state. This can be confirmed by using the banker's algorithm which ensures the prevention of deadlocks. The algorithm ensures that a process can only request resources if it will eventually be able to release them, thus preventing a deadlock.
