14.9. Deadlock and Its Avoidance

Try these first

1. 1.

   Define deadlock in the context of multithreading.

   Hint

   Think about threads and resource allocation.

2. 2.

   What is lock ordering?

   Hint

   Consider how a queue or sequence might help prevent issues.

3. 3.

   What is deadlock?

   • A thread releasing a lock
   • Two threads waiting for each other
   • An efficient use of resources

   Hint

   Think about the implication of resources being held by waiting threads.

4. 4.

   Is using a timeout for lock acquisition beneficial in preventing deadlocks?

   • True
   • False

   Hint

   Consider what happens when a thread waits too long.

5. 5.

   You are developing a multithreaded application that processes banking transactions. Describe how you would implement lock ordering to prevent deadlock when two threads access accounts concurrently.

   Hint

   Consider the order of account identifiers.

6. 6.

   Analyze a scenario where threads might frequently encounter deadlock. Propose a comprehensive strategy using both timeouts and try-lock mechanisms to ensure continuous operation.

   Hint

   Think about balancing resource access and thread activity.
