Necessary conditions for deadlock, Operating System

Assignment Help:

Here are the conditions necessary for a deadlock to occur; note that all of them are necessary, and none is suf?cient:

1. ?nite resources: the resources are held in a mutually-exclusive way, and they can be exhausted, causing waiting.

2. hold-and-wait: each thread holds one resource while waiting for another.

3. no preemption: threads only release resources voluntarily. No other thread (or the OS) can force the thread to release its resources.

4. circular wait: we have a circular chain of waiting threads.
