What are deadlocks in semaphores?
Deadlocks in semaphores occur when two or more processes are unable to proceed because each is waiting for the other to release a semaphore.
Can you give me an example of a deadlock situation?
Sure! Imagine two processes, A and B. Process A holds Semaphore 1 and waits for Semaphore 2, while Process B holds Semaphore 2 and waits for Semaphore 1. This creates a deadlock.
How can deadlocks be prevented in semaphore usage?
Deadlocks can be prevented by ensuring that all semaphores are acquired in a consistent order or by using timeout mechanisms.
What are some common strategies to resolve deadlocks?
Common strategies include process termination, resource preemption, and using a wait-die or wound-wait scheme.
