The Banker's Algorithm is used for deadlock avoidance in operating systems. It is particularly employed in resource allocation scenarios where multiple processes require access to shared resources. The algorithm ensures that resources are allocated in a way that guarantees the system remains in a safe state, meaning that there is a sequence of processes that can be executed without leading to a deadlock.
The Banker's Algorithm works by simulating the allocation of resources and checking whether the system can still fulfill all processes' maximum resource needs without falling into an unsafe state. It does this by keeping track of:
1. Available resources: The amount of each resource currently available.
2. Maximum demand: The maximum resources each process may need.
3. Allocation: The current resources allocated to each process.
4. Need: The remaining resource needs of each process.
By analyzing these factors, the Banker's Algorithm determines if it's safe to allocate a requested set of resources to a process. If the allocation will not lead to a deadlock, the resources are granted; otherwise, the request is denied or postponed until conditions are safe.
