Step 1:Access the Simulator
Access the simulator using the link below: https://10chirag10.github.io/bankers-algorithm-simulator/
Step 2:Enter Information
Enter the following Information:
- Number of Processes: 3
- Number of Resource Types: 3
- Click Generate Table
Step 3:Input Values
Enter the following data:
Step 4:Run the Algorithm
Run the algorithm and observe:
- Whether the system is in a safe state
- The safe sequence (if one exists)
Step 5:Experiment
Experiment:
- Change allocation values
- Try different resource requests
- Observe how the system responds when conditions change
Question 5Reponse Guide
The operating system may deny a request to prevent the system from entering an unsafe state. Even if resources are available at the moment, granting the request could lead to a situation where processes cannot complete, resulting in a potential deadlock.
Question 2Response Guide
In this simulation, the system did not produce a safe sequence. Only process P1 could run first, but after it completed, the remaining processes could not proceed. Because of this, no full safe sequence exists.
Question 4Response Guide
Yes, the system becomes unsafe when no processes can proceed because their needs are greater than the available resources. In this activity, after P1 completed, both P0 and P2 required more resources than were available, making the system unsafe.
Question 1 Response Guide
A safe state means the system can allocate resources to all processes in a specific order so that every process can finish without causing a deadlock. This order is called a safe sequence.
Question 3Response Guide
When the allocation for one process increases, the number of available resources decreases. This can make it harder for other processes to meet their needs, which increases the chances of the system becoming unsafe.
