Question
Which of the following condition is required for a deadlock to be possible?Group of answer choicesall of thesemutual exclusionno resource can be forcibly removed from a process holding ita process may hold allocated resources while awaiting assignment of other resources
Solution
All of these conditions are required for a deadlock to be possible.
-
Mutual Exclusion: This condition states that at least one resource must be held in a non-sharable mode. In other words, if one process is using a resource, no other process should be able to use it simultaneously.
-
No resource can be forcibly removed from a process holding it: This condition implies that resources cannot be preempted from a process. They must be released voluntarily by the process holding them.
-
A process may hold allocated resources while awaiting assignment of other resources: This condition means that a process can request additional resources while still holding on to the ones it already has.
So, the answer is "all of these".
