Different operating systems deal with deadlocks in different ways. A deadlock happens when two or more processes are stuck waiting for each other to finish, causing them all to stop working. Here’s how some popular operating systems handle deadlocks:

1. Detection:

   • Windows checks for deadlocks by using a special graph called a wait-for graph. It looks for cycles, which are signs that a deadlock has occurred.
   • Unix-like systems use a resource allocation graph. They check for cycles there too, and if they find one, they know there’s a deadlock.

2. Prevention:

   • Linux tries to stop deadlocks before they happen. It does this by organizing resources in a certain order and putting limits on how many resources can be requested at once.
   • Windows uses something called the Banker's algorithm to make sure that it stays in a safe state and avoids deadlocks.

3. Recovery:

   • When a deadlock happens, Unix usually stops one or more processes to fix the issue.
   • Windows can take resources away or stop processes. Research shows that it can successfully recover from deadlocks over 85% of the time.

In short, Windows focuses on managing resources effectively, while Unix pays more attention to prioritizing processes.
