Which one of the following is the deadlock avoidance algorithm?Group of answer choiceselevator algorithmround robin algorithmbanker's algorithmkarn's algorithm

Step 1: Break Down the Problem

To answer the question, we need to identify which algorithm from the provided options is specifically designed for deadlock avoidance in operating systems.

Step 2: Relevant Concepts

Deadlock avoidance algorithms are designed to prevent deadlock conditions by ensuring that a system never enters an unsafe state. One of the most well-known deadlock avoidance algorithms is the Banker's Algorithm.

Step 3: Analysis and Detail

• Elevator Algorithm: This is a scheduling algorithm used for disk scheduling and does not deal with deadlock avoidance.
• Round Robin Algorithm: This is a time-sharing scheduling algorithm that allocates time slices to processes and does not address deadlocks.
• Banker's Algorithm: This algorithm checks every request and simulates allocation to ensure that the system remains in a safe state, thus avoiding deadlock.
• Karn's Algorithm: This is primarily related to network protocols and does not pertain to deadlock management.

Step 4: Verify and Summarize

From the analysis, only the Banker's Algorithm is related to deadlock avoidance. The other algorithms listed do not serve this purpose.

Final Answer

The deadlock avoidance algorithm from the given options is the Banker's Algorithm.
