Deadlock Recovery

 deadlock recovery techniques like wound-wait and wait-die are used to handle situations where processes are waiting for resources, and a deadlock might occur. Let's break them down:

Wound-Wait:

Think of it like being a bit impatient. If a process needs a resource held by another process, it checks the age or "wound" of the other process.

If the other process is "younger" (started later), then the current process waits.

If the other process is "older" (started earlier), the current process can "wound" it, meaning it can force the older process to release its resources, preventing a deadlock.

Wait-Die:

This approach is more patient. If a process needs a resource held by another process, it checks the age or "age difference" between them.

If the other process is "younger," the current process waits.

If the other process is "older," the current process can "die," meaning it gives up and gets restarted, allowing the older process to continue and preventing a deadlock.

In both cases, the idea is to avoid deadlocks by carefully managing how processes interact.
