An operating system makes use of Banker’s algorithm to allocate 12 printers. Printers will be allocated'to a process requesting them only if - there are enough available printers to allow it to run to completion.
User 1 using 7 printers and will need at most a total of 10 printers.
User 2 is using 1 printer and will need at most 4 printers.
User 3 is using 2 printers and will need at most 4 printers.
Each user is currently requesting 1 more printer, Which of the following is true?
  • a)
    The operating system will grant a printer to User 1 only.
  • b)
    The operating system will grant a printer to User 2 only.
  • c)
    The operating system will grant a printer to User 3 only.
  • d)
    The operating system will not grant any more printers until some are relinquished.
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
An operating system makes use of Banker’s algorithm to allocate ...
Total printers = 12
Printers allocated to user 1, user 2 and user 3 are 7, 1 and 2 respectively

So, only safest sequence is V3 first then either or V3. So, operating system will grant printer to user 3 only.

An operating system makes use of Banker’s algorithm to allocate ...
The Banker's algorithm is a resource allocation and deadlock avoidance algorithm that is commonly used in operating systems. It is used to determine whether a particular system state is safe or not by simulating the allocation of resources to processes and checking for any potential deadlock situations.

In an operating system that makes use of the Banker's algorithm, the system keeps track of the available resources and the maximum resources that each process may need. When a process requests resources, the system checks if granting those resources would result in a safe state. If it does, the resources are allocated to the process, otherwise, the process is made to wait until the resources become available.

The Banker's algorithm helps prevent deadlock situations by ensuring that resources are allocated in a way that guarantees the system will not reach a state where no process can progress. It uses a mathematical model known as the safe state to determine whether a system state is safe or not.

Overall, an operating system that makes use of the Banker's algorithm can effectively manage resource allocation and prevent deadlock situations, thus improving the overall stability and reliability of the system.
