In a functional dependency, any attribute on the right side of the arrow is said to be a dependent attribute. Therefore, the correct answer is (d).

A functional dependency is a relationship between two sets of attributes in a relation (or table) such that the values of one set of attributes (called the determinant) uniquely determine the values of the other set of attributes (called the dependent attributes). This relationship is represented by an arrow from the determinant to the dependent attributes.For example, consider a relation that stores information about employees, with attributes such as employee ID, name, department, and salary. If we know the employee ID, we can uniquely determine the name, department, and salary of the employee. Therefore, we can say that there is a functional dependency between the employee ID and the name, department, and salary attributes.

In order to accommodate 325 subnets, you need to borrow 9 bits from the 150.25.0.0 network. This will give you a total of 512 subnets.

To figure out how many bits need to be borrowed, you use the formula [tex]2^n[/tex], where n is the number of bits you need to borrow. In this case, n = 9, since [tex]2^9 = 512[/tex]. To accommodate 325 subnets, 9 bits need to be borrowed from the host portion of the IP address to subnet the given 150.25.0.0 network.

The formula used for determining the number of bits needed to accommodate the given number of subnets is:

bits = log2(subnets)rounded up to the nearest integer.

The calculation will be: bits = log2(325)bits = 8.3567 rounded up to the nearest integer = 9

In a LAN topology, the Spanning Tree Protocol (STP) is used to prevent loops and ensure a loop-free path for data traffic.

In STP, the switch with the lowest bridge priority value is elected as the root bridge, which serves as the reference point for all other switches in the network.

To make it least likely for a switch to be selected as the root, it should have the highest bridge priority value. By default, all switches have a bridge priority value of 32768, and the lower the value, the higher the priority.

Therefore, assigning a higher bridge priority value to a switch will make it less likely to be selected as the root.

There can be various reasons why capacity alone does not dictate the bottleneck. One of the most probable reasons for this is that capacity is only one factor among several that can impact the bottleneck.

In manufacturing, capacity refers to the maximum amount of output that a system or machine can produce within a given timeframe. The bottleneck, on the other hand, refers to the slowest part of the manufacturing process that restricts the flow of production.

What is the Bottleneck?

The bottleneck is the slowest part of the manufacturing process that restricts the flow of production. The bottleneck affects the overall capacity of the manufacturing process, which is why it is important to identify and resolve bottlenecks as soon as possible. However, capacity alone does not dictate the bottleneck because there are other factors that can impact the bottleneck as well.

For example, the bottleneck could be caused by a shortage of raw materials or labor, equipment breakdown, or even poor communication between team members. Additionally, certain steps in the manufacturing process may require more time or effort than others, which could cause the bottleneck to shift from one area to another.

In conclusion, capacity is an important factor to consider when identifying and resolving bottlenecks in manufacturing. However, it is not the only factor that impacts the bottleneck, and other factors such as raw materials, labor, equipment, and communication must also be taken into account.

Here's an example of how to print all the elements stored in a linked list in Java, assuming that the node class has a "getElement()" method that returns the value stored in the node:

public void printList() {

   Node current = first; // Start at the beginning of the list

   while (current != null) { // Traverse the list until the end

       System.out.println(current.getElement()); // Print the element at the current node

       current = current.getNext(); // Move to the next node in the list

   }

}

This method starts at the beginning of the list by setting the current variable to the first node in the list. It then enters a loop that continues until current is null, which signifies the end of the list. Within the loop, it prints the value stored in the current node by calling the getElement() method. It then moves to the next node in the list by setting current to the next node's reference, which is obtained using the getNext() method.

Overall, this method prints all the elements stored in the linked list by traversing the list from the beginning to the end, printing the value at each node along the way.
