Question

Quizplus · Accepted Answer

In a system resource-allocation graph, a process requests for a resource by creating a directed edge from the process to the resource, which is called a request edge. When the resource is granted to the process, the edge becomes an assignment edge, indicating that the resource has been allocated to the process. Therefore, option C is the correct choice. Option A is incorrect because a directed edge from a process to a resource is called a request edge, not an assignment edge. Option B is incorrect because a directed edge from a resource to a process does not exist in a system resource-allocation graph. Option D is incorrect because at least one of the other options is correct.
