Question

Computer Science

Consider five threads: TO, T1, T2, T3, T4; and three resource types:
A, B, C. Here, A has 12 instances, B has 8 instances, and C has 9
instances. The current state of the system is presented on Table 1,
where 'Allocation' represents the number of instances for each
resource type currently allocated to each thread, and 'Max'
represents the maximum demand of each thread. Answer the
following questions based on Banker's Algorithm:
a. Is the system in a safe state now?
b. If the system is in a safe state, what is the corresponding
safe sequence? It would suffice to present one safe
sequence in your answer. Note: You must show the steps
how you found the safe sequence.
