Question
The circular wait condition can be prevented by ____________a.Defining a linear ordering of resource typesb.Using pipesc.Using threadd.All of the mentioned
Solution
The circular wait condition can be prevented by defining a linear ordering of resource types. This is a strategy to avoid deadlock in a concurrent computing environment.
Here's a step-by-step explanation:
-
Define a global ordering of all resource types. For example, if we have three types of resources R1, R2, and R3, we can order them as R1<R2<R3.
-
Ensure that each process requests resources in an increasing order of enumeration. In other words, a process can request for a resource Rj only if it has not requested any resource Ri such that i>j.
-
Ensure that a process releases its resources in a decreasing order of enumeration.
By following this strategy, we can prevent the circular wait condition and thus avoid deadlock.
The other options mentioned - using pipes and using thread - are not directly related to preventing the circular wait condition.
