The banker's algorithm is useful in a system with multiple instances of each resource type is a "true" statement.
What is banker's algorithm?
The banker's algorithm is an assignment and deadlock avoidance algorithm which tests for security by simulating allocation for predefined maximum possible amounts among all resources, then performs a "s-state" check to test for possible activities before deciding as to if allocation should continue.
Some key features regarding banker's algorithm are-
- Banker's algorithm is so titled because it is employed in banking systems to determine whether or not a loan can be granted to a person.
- Assume there are n account holders in a bank, and the total amount of their money is S.
- When an individual applies for a loan, the bank first deducts their loan amount from total amount of money in the bank, and if the leftover amount is larger than S, just the loan is approved.
- It is done because the bank could easily remove money from all of the account holders.
- To put it another way, the bank never would arrange its funds in a way that it may no longer meet the demands of all of its clients.
- The bank would always strive to be in a secure situation.
