Q2. What is Bankers algorithm
Ans. 
Banker's algorithm is a resource allocation and deadlock avoidance algorithm used in operating systems.
• Used to avoid deadlock in a system by ensuring that resources are allocated safely

• Works by keeping track of available resources and the maximum resources each process can request

• Allocates resources only if the system remains in a safe state

• Example: A system has 3 types of resources A, B, and C. Process P1 can request ...read more
