Question

In a system resource-allocation graph, ____.A) a directed edge from a process to a resource is called an assignment edge

B) a directed edge from a resource to a process is called a request edge
C) a directed edge from a process to a resource is called a request edge
D) None of the above

Answer 1

In a system resource-allocation graph, a directed edge from a resource to a process is called a request edge.

Step-by-step explanation:

In a system resource-allocation graph, the correct option is B) a directed edge from a resource to a process is called a request edge.

This graph is used to represent the allocation of resources to different processes in a system. In this graph, processes are represented by nodes, and resources are represented by edges.

When a process requests a resource, a directed edge from the process node to the resource node is added, indicating that the process is requesting that resource. On the other hand, when a resource is assigned to a process, a directed edge from the resource node to the process node is added, indicating that the resource has been assigned to that process.

Answer 2

In a system resource-allocation graph, B) a directed edge from a resource to a process is called a request edge

What happens in a system resource-allocation graph?

In a system resource-allocation graph, a directed edge represents an allocation or request for a resource. A directed edge from a process to a resource indicates that the process has been allocated the resource. This type of edge is called an assignment edge.

A directed edge from a resource to a process indicates that the process has requested the resource. This type of edge is called a request edge.

Therefore, the statement "a directed edge from a resource to a process is called a request edge" is correct.
