If we assume there are n inodes in the UNIX file system, then the maximum amount of physical storage accessible by the system would be: n * 263,343.75 MB Note that the actual maximum storage capacity would also depend on other factors such as the amount of free space on the disk, file system overhead, and the size of the metadata (including the inodes themselves).

To calculate the maximum amount of physical storage accessible by this UNIX file system, we need to consider the number of blocks that can be addressed by the inode.

Each inode has 12 direct block pointers, which can address 12 blocks directly. Each block is 16K, so the total amount of data that can be addressed by the direct pointers is:

12 blocks * 16K/block = 192K

In addition to the direct pointers, each inode has a singly indirect pointer, which can address an additional 16K blocks, or 256 direct blocks. The doubly indirect pointer can address an additional 256 * 256 blocks, or 65,536 direct blocks. Finally, the triply indirect pointer can address an additional 256 * 256 * 256 blocks, or 16,777,216 direct blocks.

So the total number of blocks that can be addressed by each inode is:

12 (direct) + 256 (singly indirect) + 65,536 (doubly indirect) + 16,777,216 (triply indirect) = 16,843,020 blocks

Each block is 16K, so the total amount of data that can be addressed by each inode is:

16,843,020 blocks * 16K/block = 269,488,320K or 263,343.75 MB

Therefore, the maximum amount of physical storage accessible by this UNIX file system would depend on the number of inodes in the file system.

The Java access specifier that can be used on a class member so it can be accessed by a different class in a different package is the "public" access specifier. When a member of a class is declared as public, it can be accessed from anywhere, including other packages.

This allows classes from different packages to interact with each other and share information. On the other hand, the default access specifier (also known as package-private) limits access to members within the same package. This means that if a member is not explicitly declared with an access specifier, it will have package-private access by default. In addition, there are two other access specifiers in Java: "private" and "protected". The private access specifier limits access to only within the same class, while the protected access specifier allows access within the same package and in subclasses. Therefore, to allow a class member to be accessed by a different class in a different package, the public access specifier should be used.

1600 bytes of data were originally sent by the source before the data in the specified fragment.

When a source sends a large IP packet that exceeds the Maximum Transmission Unit (MTU) size of a network, the packet gets fragmented into smaller pieces or fragments. Each fragment carries a portion of the original data and has an offset value that indicates its position in relation to the original packet. In this case, if the offset value of a fragment is 200, it means that 200 bytes of data have been sent before the data in this specific fragment.

Since each fragment typically carries 8 bytes of overhead (IP header), the total amount of data originally sent by the source before this fragment would be 200 bytes + (8 bytes * 200 fragments) = 1600 bytes. Therefore, the original data size sent by the source before this fragment is 1600 bytes.

In order to write a static method named "extremes" that takes a List of Integer as a parameter and moves the smallest element of the list to the front and the largest element to the end, you can use the following code:

```
public static void extremes(List elements) {
   // Initialize the index of the minimum and maximum elements
   int minIndex = 0;
   int maxIndex = 0;
   // Iterate through the elements of the list to find the minimum and maximum elements
   for (int i = 1; i < elements.size(); i++) {
       if (elements.get(i) < elements.get(minIndex)) {
           minIndex = i;
       }
       if (elements.get(i) > elements.get(maxIndex)) {
           maxIndex = i;
       }
   }
   // Swap the minimum element with the first element
   Integer temp = elements.get(0);
   elements.set(0, elements.get(minIndex));
   elements.set(minIndex, temp);
   // If the maximum element is not already at the end, swap it with the last element
   if (maxIndex != elements.size() - 1) {
       temp = elements.get(elements.size() - 1);
       elements.set(elements.size() - 1, elements.get(maxIndex));
       elements.set(maxIndex, temp);

```
This method first initializes two variables "minIndex" and "maxIndex" to 0, representing the indices of the minimum and maximum element in the list. It then iterates through the elements of the list using a for loop and updates these indices if it finds a new minimum or maximum element. After the loop, it swaps the minimum element with the first element of the list and the maximum element with the last element of the list (if the maximum element is not already at the end).

So, on average, there are 4 customers waiting in the queue by single-server queue model.

To calculate the average number of customers waiting in a single-server queue model, we can use the following formula:

Lq = (λ * Wq)

where Lq is the average number of customers waiting in the queue, λ is the arrival rate, and Wq is the average time a customer spends waiting in the queue.

We are given that the average interarrival time is 4 minutes, so the arrival rate can be calculated as:

λ = 1/4 = 0.25 customers per minute

We can also calculate the average time a customer spends waiting in the queue using Little's Law:

Wq = Lq / λ

Since we don't know Lq yet, we can use the formula for the expected waiting time in the queue:

Wq = (C * S^2) / (2 * (1 - ρ))

where C is the average number of customers in the system, S is the average service time, and ρ is the server utilization.

Assuming that the server can handle one customer every 8 minutes (since the average time a customer spends waiting is 8 minutes), the service time is 8 minutes. Also, since there is only one server, the server utilization is:

ρ = λ * S = 0.25 * 8 = 2

Since ρ is greater than 1, this system is unstable and the expected waiting time is infinite. However, for the purposes of this question, we will assume that the server utilization is less than 1 (i.e., the system is stable).

Plugging in the values, we get:

Wq = (C * S^2) / (2 * (1 - ρ))

Wq = (C * 8^2) / (2 * (1 - 0.25 * 8))

Wq = (64C) / 6

We also know that:

Wq = Lq / λ

Substituting in the values, we get:

(Lq / 0.25) = (64C) / 6

Lq = (64C * 0.25) / 6

Lq = (16C) / 3

Now, we can solve for C using Little's Law:

C = λ * W

C = λ * (Wq + S)

C = λ * (Lq / λ + S)

C = Lq / λ + S

Substituting in the values, we get:

C = (16C / 3) / 0.25 + 8

C = (16C / 12) + 8

C = (4C / 3) + 8

C - (4C / 3) = 8

C / 3 = 8

C = 24

Therefore, the average number of customers waiting in the queue is:

Lq = (λ * Wq)

Lq = (0.25 * (16C / 3))

Lq = 4

So, according to the single-server queue model, the average number of customers waiting in the queue is 2 customers.

To find the average number of customers waiting in a single-server queue, we will use the Little's Law formula. Little's Law states that:
L = λW
Where:
L = average number of customers waiting in the queue
λ = average arrival rate of customers (customers per minute)
W = average time a customer spends in the queue (minutes)
We are given that the average waiting time (W) is 8 minutes, and the average interarrival time is 4 minutes. To find the average arrival rate (λ), we take the reciprocal of the interarrival time:
λ = 1 / 4 minutes = 0.25 customers per minute
Now we can plug these values into Little's Law:
L = (0.25 customers per minute) × (8 minutes)
L = 2 customers
So, according to the single-server queue model, the average number of customers waiting in the queue is 2 customers.

True, most companies prefer to use the symmetric-key encryption method over the asymmetric-key encryption method in conducting e-business. This preference is due to several factors, including efficiency and performance.

Symmetric-key encryption method involves the use of a single secret key for both encryption and decryption of data. This method offers faster encryption and decryption speeds compared to asymmetric-key encryption, making it more suitable for processing large amounts of data, which is common in e-business operations. Asymmetric-key encryption, on the other hand, utilizes two separate keys: one for encryption and the other for decryption. While this method provides enhanced security, as the decryption key remains private and only known to the recipient, it is computationally more intensive and slower in comparison to symmetric-key encryption.
