The most commonly used LAN for fiber transmission links is the 850 nm multimode fiber.

This type of fiber is designed to carry multiple signals over the same link, allowing for faster data transmission and greater bandwidth. It can be used for short-distance transmission over up to a few kilometers. It is a relatively low-cost solution and requires less power than single-mode fiber. The 850 nm multimode fiber uses a relatively wide light source, which is able to spread the signal over a greater distance with less attenuation. This makes it a great choice for short-distance applications.

Additionally, it is more immune to noise than single-mode fiber and is less susceptible to changes in temperature. It is an ideal choice for fiber-optic networks that are used in LANs, such as those used for Ethernet, data centers, and storage area networks.

Yes, that is correct. Encapsulation is the process of breaking a message or data into smaller packets or frames, adding control information such as source and destination addresses, error detection codes, and other necessary information, and transmitting the message through a transmission medium such as a wired or wireless network.

This process helps to ensure that the data is transmitted efficiently and reliably over the network.

Encapsulation is an essential process used in computer networking to transmit data over a network. When data is sent over a network, it is divided into small packets, which are then encapsulated with the necessary control information such as source and destination addresses, error detection codes, and other necessary information.

Each packet is given a sequence number so that the receiving device can reassemble the packets in the correct order. This process is essential for ensuring that the data is transmitted reliably and accurately over the network. Once the packets reach their destination, they are de-encapsulated to extract the original message or data.

The correct option for an empty singly linked chain is "the reference to the first node is null." Therefore the correct option is option B.

A singly linked list, also known as a one-way linked list, is a type of linked list. It is a group of nodes that are linked to one another in a linear order. Each node has a data component and a pointer component pointing to the next node in the sequence.

When we speak of an empty singly linked chain, it is a chain that has no nodes. Therefore, the reference to the first node is null because there are no nodes to reference. So, "the reference to the first node is null" is the correct answer among the given options for an empty singly linked chain. Therefore the correct option is option B.

To define a function named SortVector that takes a vector of integers as a parameter and sorts it in descending order (highest to lowest), you can use the bubble sort algorithm.

Here's a step-by-step explanation and code in C++:

1. Define the SortVector function:

```cpp
void SortVector(vector& myVec) {
   int n = myVec.size();
   for (int i = 0; i < n-1; i++) {
       for (int j = 0; j < n-i-1; j++) {
           if (myVec[j] < myVec[j+1]) {
               swap(myVec[j], myVec[j+1]);
           }
       }
   }
}
```

2. Write the main program:

```cpp
#include
#include
using namespace std;

void SortVector(vector& myVec);

int main() {
   int n, num;
   cin >> n;

   vector myVec;
   for (int i = 0; i < n; i++) {
       cin >> num;
       myVec.push_back(num);
   }

   SortVector(myVec);

   for (int i = 0; i < n; i++) {
       cout << myVec[i] << ",";
   }

   return 0;
}
```

With this code, if the input is: 5​ 10​ 4​ 39​ 12​ 2​,

the output is : 39,12,10,4,2, as the function SortVector modifies the vector by sorting the elements in descending order (highest to lowest) using the bubble sort algorithm.

To print the contents of the array 'inventory', you can call the function 'printarray' like this: printarray(inventory);

This function will loop through the array 'inventory' and print each item on a separate line. It will display the contents of the array in the same order they were entered.

To break it down further, the function 'printarray' takes an array as its argument. It then begins a loop and uses the array's length as the limit of the loop. For each iteration, the function prints out the item at the current index of the array. This process is repeated until the end of the array is reached.

In conclusion, calling the function 'printarray' with the argument 'inventory' will print out the contents of the array 'inventory'.

   prize_money = 37500 * num_medals

   # Calculate the total award money received

   total_award_money = prize_money + total_sponsorship

def calculate_average_award_money(total_award_money, num_medals):

   average_award_money = total_award_money / num_medals

   return average_award_money

# Get user inputs

num_medals = int(input("Enter Gold Medals Won: "))

total_sponsorship = int(input("How many dollars were you sponsored in total?: "))

# Calculate total award money

total_award_money = calculate_award_money(num_medals, total_sponsorship)

# Calculate average award money

average_award_money = calculate_average_award_money(total_award_money, num_medals)

# Output the results

print("Your prize money is:", total_award_money)

print("Your average award money per gold medal was:", average_award_money)

The first function, calculate_award_money, takes two parameters: num_medals (the number of gold medals won) and total_sponsorship (the total amount of sponsorship received). It calculates the total amount of award money received by multiplying the number of gold medals by the prize money for each medal ($37,500) and adding the total sponsorship. It then returns this value.

Therefore, the second function, calculate_average_award_money, takes two parameters: total_award_money (the total amount of award money received) and num_medals (the number of gold medals won). It calculates the average award money per gold medal by dividing the total award money by the number of gold medals. It then returns this value.
