- Q2. Multithreading and how to remove deadlock
- Ans.
Multithreading allows multiple threads to run concurrently. Deadlock can be removed by avoiding circular wait, preempting resources, and using timeouts.
Avoid circular wait by ensuring threads acquire resources in the same order
Preempt resources by releasing them if a thread cannot acquire all necessary resources
Use timeouts to prevent threads from waiting indefinitely for resources
