Question

For which deadlock management strategy, the Ostrich algorithm is used?

• A. Deadlock prevention
• B. Deadlock avoidance
• C. Deadlock ignorance
• D. Deadlock detection

Hint:

UNIX and many practical operating systems often adopt the Ostrich approach because deadlocks are rare and the overhead of handling them continuously may not be justified.

Answer 1

The Correct Option is C

Concept: The Ostrich Algorithm follows the philosophy: \[ \text{``Ignore the problem if the cost of solving it exceeds the damage caused by it.''} \] This strategy assumes deadlocks occur very rarely and therefore ignores them.

Step 1: Understand the Ostrich Algorithm.
Instead of preventing, avoiding, or detecting deadlocks, the operating system simply ignores them.

Step 2: Reason behind the approach.
In many systems, deadlocks occur extremely infrequently. Implementing sophisticated deadlock handling mechanisms may introduce unnecessary overhead.

Step 3: Identify the corresponding strategy.
Since the algorithm ignores deadlocks, \[ \boxed{\text{Deadlock Ignorance}} \] is the correct answer.
