Question 1

What does the Safety Algorithm check for?

If all processes can start
If the system is in a safe state
If resources are enough

💡 Hint: Think about the final state of process execution.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

In a system with 5 total resources and three processes: Process A requires [1, 2], Process B requires [2, 0], and Process C requires [3, 2]. If current allocations are [1, 0], [1, 1], and [1, 0] respectively, show if this state is safe.

💡 Hint: Work through each process and check if they can finish given the resources.

Challenge 2 Hard

Create and analyze a system with four processes needing various resources. Determine safe and unsafe states based on your configuration.

💡 Hint: Use a diagram or table to simplify resource tracking.
