Topic connected to the question: Deadlock Avoidance

Suppose that there are 12 resources available to three processes. At time 0, the following data is collected. The table indicates the process, the maximum number of resources needed by the process, and the number of resources currently owned by each process.

Is the system in a safe state? Why?

**Process Resource Allocation Table**

This table presents information on three processes (P₀, P₁, P₂) regarding their resource needs and holdings:

- **Process**: Identifiers for each process (P₀, P₁, P₂).
- **Maximum Needs**: The total units of resources each process may need to complete its operation.
  - P₀: 10 units
  - P₁: 3 units
  - P₂: 7 units

- **Currently Holding**: The units of resources currently allocated to each process.
  - P₀: 4 units
  - P₁: 2 units
  - P₂: 4 units

This table helps in understanding how resources are distributed among different processes, which is crucial for resource management and preventing deadlock in operating systems.
