📄 Passage
Read the below passage and answer the questions.
The Banker's Algorithm is a critical deadlock avoidance method in operating systems, designed to facilitate resource allocation without causing deadlock. It operates by maintaining information about the maximum resources. Each process may require, the current allocated resources and the available resources in the system. The algorithm checks each resource request to determine, if granting it would leave the system in a safe state, meaning that there is always a sequence in which all processes can complete their execution without getting stuck due to resource unavailability. Each process must specify its maximum demand for each resource type before it starts execution. When a process requests additional resources, the algorithm checks if granting the request will keep the system in a safe state. If so, the resources are allocated otherwise the process must wait until its request can be safely fulfilled.
What is the significance of the Banker's algorithm in terms of resource management ?
1.It enures that all processes can finish their execution without deadlock.✓ Correct
2.It eliminates the need for processes to request resources.
3.It accelerates the execution of critical sections in processes.
4.It minimizes the number of context switches between processes.
Solution
The correct answer is It ensures that all processes can finish their execution without deadlock.
Key Points
The Banker's Algorithm is a deadlock avoidance method used in operating systems to ensure that resource allocation is done in such a way that the system remains in a safe state.
It maintains information about the maximum resources each process may require, the current allocated resources, and the available resources in the system.
The algorithm checks each resource request to determine if granting it would leave the system in a safe state, meaning that there is always a sequence in which all processes can complete their execution without getting stuck due to resource unavailability.
By ensuring a safe state, the algorithm prevents deadlock, which is a situation where processes are unable to proceed because each is waiting for resources held by others.
Additional Information
Option 2: It eliminates the need for processes to request resources. This is incorrect because the Banker's Algorithm does not eliminate the need for resource requests; instead, it manages these requests to avoid deadlock.
Option 3: It accelerates the execution of critical sections in processes. This is incorrect because the primary goal of the Banker's Algorithm is to avoid deadlock, not to accelerate execution of critical sections.
Option 4: It minimizes the number of context switches between processes. This is incorrect because the algorithm focuses on resource allocation and deadlock avoidance, not on minimizing context switches.
