What are some examples of deadlock and livelock in computer systems?

Deadlock occurs when two or more processes are unable to proceed because each is waiting for the other to release resources. For example, if Process A holds Resource 1 and waits for Resource 2, while Process B holds Resource 2 and waits for Resource 1, a deadlock occurs.

Can you give me a livelock example?

Sure! A livelock happens when processes continuously change states in response to each other without making progress. For instance, if two processes are trying to access a shared resource and keep yielding to each other, they may keep changing their states but never actually proceed.

How can we prevent deadlocks?

Deadlocks can be prevented by ensuring that at least one of the necessary conditions for deadlock cannot hold. This can be achieved through resource allocation strategies like avoiding circular wait or using a timeout mechanism.

What tools can help detect deadlocks?

Tools like deadlock detection algorithms, resource allocation graphs, and monitoring systems can help identify deadlocks in a system.
