IP addresses belong to networks, not to the devices attached to these networks.

IP addresses are used to uniquely identify and locate devices within a network. They serve as the addressing scheme for communication between devices over the internet or a local network. IP addresses are assigned to networks, and devices connected to the network are then assigned IP addresses from that network's range.

Devices, such as computers, servers, and smartphones, are assigned IP addresses based on the network they are connected to. The IP address allows devices to send and receive data across the network. Multiple devices within a network can have different IP addresses, but these addresses are associated with the network to which the devices are connected.

Wireshark tool is being used to detect a potential DDoS attack.

If a denial-of-service (DDoS) attack is happening on the network, it is likely that there will be an abnormal increase in traffic to the targeted IP address (in this case, 128.28.1.1).

Using Wireshark, packets captured using the tcp.flags.syn filter can provide information on whether the traffic is originating from multiple sources, which can indicate a DDoS attack.

The SYN flag is set during the initial connection request between two devices.

By analyzing the traffic, including the source IP addresses and the frequency of connection requests, it is possible to identify a DDoS attack and take necessary actions to mitigate it.

The Bellman-Ford algorithm is used to find the shortest path from a single source vertex to all other vertices in a weighted graph. It does this by relaxing the edges in the graph repeatedly, gradually improving the estimates of the shortest path until it reaches the optimal solution.

(a) In the Bellman-Ford algorithm, the relax function is called for each edge in the graph a total of |V|-1 times, where |V| is the number of vertices in the graph. Therefore, if the graph has n vertices, then the relax function would be called n-1 times.

(b) The Bellman-Ford algorithm would return true if there are no negative weight cycles in the graph, meaning that there is a shortest path from the source vertex to all other vertices. It would return false if there is a negative weight cycle, which means that there is no shortest path, as one can keep going around the negative cycle and decreasing the distance infinitely.

(c) If we reverse edge (2,4) and make the weight negative, this would create a negative weight cycle in the graph. In this case, the Bellman-Ford algorithm would still be called n-1 times, but it would return false instead of true, as there is no shortest path due to the negative weight cycle.

The fragment offset field contains information that allows the receiving end to put all the parts of a fragmented packet back together in the correct order.

When a packet is too large to be transmitted through a network, it is divided into smaller fragments. Each of these fragments contains a portion of the original data and is transmitted separately.

The fragment offset field, found within the Internet Protocol (IP) header, is essential for the reassembly of these fragments at the receiving end. It provides information on the position of each fragment within the original packet, ensuring that the receiving device can accurately reconstruct the original packet by placing the fragments in the correct sequence.

As the fragments arrive at their destination, the receiving device uses the fragment offset field to determine the correct order of the fragments. It also takes into account other relevant header fields, such as the "More Fragments" flag, which indicates whether additional fragments are still being transmitted. Once all the fragments have arrived, the receiving device can then reassemble the original packet based on the provided information.

In summary, the fragment offset field plays a vital role in the transmission and reassembly of large packets within a network. It ensures that the receiving end can accurately reconstruct the original packet, enabling efficient and reliable communication between devices.

To modify the solution to exercise 9, we need to add a new column that calculates the average balance due for each vendor in the Invoices table. This column should also have a cumulative average by balance due. We will also need to modify the SELECT statement to use a named window for the last two aggregate window functions.

To add the new column, we can use the AVG() function and a window function to calculate the average balance due for each vendor. We can then use the SUM() function and another window function to calculate the cumulative average by balance due. Here is the modified solution:

SELECT VendorID, BalanceDue,
      AVG(BalanceDue) OVER (PARTITION BY VendorID ORDER BY InvoiceDate ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS AvgBalanceDue,
      SUM(BalanceDue) OVER (PARTITION BY VendorID ORDER BY InvoiceDate ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) / COUNT(*) OVER (PARTITION BY VendorID ORDER BY InvoiceDate ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS CumulativeAvgBalanceDue
FROM Invoices;

In this modified solution, the first window function calculates the average balance due for each vendor using the AVG() function. The second window function calculates the cumulative average by balance due using the SUM() function and the COUNT() function. We use the PARTITION BY clause to group the data by VendorID, and the ORDER BY clause to order the data by InvoiceDate.

By adding a new column that calculates the average balance due for each vendor in the Invoices table, and modifying the SELECT statement to use named windows for the last two aggregate window functions, we have created a more comprehensive solution to exercise 9.

The ALU receives the function code as input and performs the corresponding operation on the operands, based on the instruction being executed.

The company that owns every single IP address with 9 as the first octet is IBM (International Business Machines Corporation). IBM is a multinational technology and consulting company, known for its contributions to the development of modern computing technology.

IP addresses are divided into four octets, each ranging from 0 to 255, and are used to uniquely identify devices on the internet. The allocation of IP addresses is managed by the Internet Assigned Numbers Authority (IANA) and its regional registries. When the internet was in its early stages, some large corporations, like IBM, were granted a whole Class A IP address block, which is characterized by having the same number in the first octet.

In IBM's case, that number is 9. As a result, all IP addresses that begin with the number 9 are owned by IBM. This allocation system has evolved over time, and IP addresses are now managed under the Classless Inter-Domain Routing (CIDR) system to improve efficiency and address the growing demand for IP addresses.

The printed as a result of executing the code segment is 4 16.

So, the correct answer is A.

The code segment is a for loop that starts with k=0 and runs as long as k<20, incrementing k by 2 each time.

Within the loop, there is an if statement that checks if k%3 is equal to 1. If it is, then k is printed followed by a space.

To determine what is printed as a result of executing the code segment, we can follow the steps of the loop.

The first time through the loop, k is 0. Since 0%3 is not equal to 1, nothing is printed. The second time through the loop, k is 2.

Again, since 2%3 is not equal to 1, nothing is printed.

This pattern continues until k reaches 4.

When k=4, 4%3 is equal to 1, so "4" is printed followed by a space.

The loop then continues, incrementing k to 6, 8, 10, 12, 14, 16, 18, but none of these values satisfy the if statement's condition, so nothing else is printed.

Therefore, the answer is option (a): "4 16" is printed as a result of executing the code segment.
