The Banker’s Algorithmis used to avoid deadlocks in a computer system. It is a resource allocation and deadlock avoidance algorithm that was first described by Edsger Dijkstra. The algorithm is used to determine whether a system is in a safe state, where it can allocate resources to processes without causing a deadlock.

The algorithm is used to determine whether a system is in a safe state, where it can allocate resources to processes without causing a deadlock.
The Banker’s Algorithm is used in operating systems to ensure that the system avoids deadlock and manages resources efficiently in a multi-process or multi-threaded environment. It achieves this by simulating the way a bank allocates resources to customers while ensuring solvency.
In practical terms, the algorithm keeps track of the total resources available, the resources currently allocated to processes, and the resources that will be requested by processes in the future. By maintaining these records, it can determine if granting a resource request would potentially lead to a deadlock (where processes are stuck waiting indefinitely for resources that other processes hold) or if it’s safe to allocate resources without causing such a deadlock.
The algorithm operates in several phases:
Overall, the Banker’s Algorithm plays a crucial role in ensuring the stability and efficiency of resource allocation in operating systems, thereby enhancing system reliability and preventing resource contention issues that could lead to system failures or deadlock scenarios.
In a multi-process operating system, the resource allocation algorithm is known as the Banker’s Algorithm. It is utilized to manage resource allocation. It’s used to make sure that a group of programs on a single computer can share the resources they have (like CPU time, memory, I/O devices, etc.). fairly and effectively.
The Investor’s Calculation works by reproducing a ledger for each interaction, where the assets distributed to the cycle are treated as stores into the record. The process’s “funds,” or resources, are checked by the algorithm to see if they are sufficient to allocate the requested resources. In the event that it does, the allocation is carried out, and the process’s account is updated in line with this. The allocation is stopped until sufficient resources are available.
The algorithm ensures that no process can acquire more resources than it has been allocated and that no process can exceed its resources. This ensures that processes can run safely and effectively while also preventing deadlocks.
