To defend against MAC Flooding Attack by implementing Port Security using scaly, you can write a Python script as follows: The implementation of port security has the following steps: Step 1: Store all the MAC addresses that are seen by the switch ports.
Step 2: Whenever a new MAC address is detected on the port, check whether the MAC address exists in the known list of MAC addresses. Step 3: If the MAC address already exists in the known MAC address list, then drop the packet received from the new MAC address and generate an alert. If the MAC address does not exist in the known MAC address list, then add the new MAC address to the known MAC address list.
In this Python script, scapy library is used to capture packets and extract their source MAC addresses. The script stores these MAC addresses in a dictionary with switch ports as the keys. Whenever a new MAC address is detected on a port, the script checks if the MAC address already exists in the known MAC address list. If it does, then it drops the packet and generates an alert. If not, then it adds the new MAC address to the known MAC address list and allows the packet to pass through. Here's the script:```pythonfrom scapy.all import *import osimport sysimport timefrom datetime import datetime# Dictionary to store MAC addresses and corresponding portsmac_dict = {}# Dictionary to store last time a MAC address was seenmac_lastseen = {}# Number of packets to capture per portn_packets = 100def get_mac(pkt): if pkt.haslayer(Ether): return pkt[Ether].src else: return Nonedef pkt_callback(pkt): mac = get_mac(pkt) if mac is None: return port = pkt.sniffed_on if mac in mac_dict: if mac_lastseen[mac] < time.time() - 300: print("MAC address", mac, "has reappeared on port", port) else: print("MAC flooding detected for MAC address", mac, "on port", port) return if len(mac_dict[port]) < n_packets: mac_dict[port].add(mac) mac_lastseen[mac] = time.time() else: print("Port security violation detected for port", port, "- maximum number of MAC addresses exceeded") returnif __name__ == "__main__": if len(sys.argv) != 2: print("Usage: python port_security.py ") sys.exit(1) interface = sys.argv[1] print("Starting port security on interface", interface) for port in range(1, 25): mac_dict[port] = set() mac_lastseen[port] = 0 sniff(prn=pkt_callback, iface=interface)```

What action(s) from the CRUD method should be used to describe the required data usage in the case of the function name is "Take delivery of a new goods" for the entity types: GOODS and DELIVERY?
The CREATE and UPDATE actions from the CRUD method should be used to describe the required data usage in the case of the function name "Take delivery of new goods" for the entity types GOODS and DELIVERY.
This is because CREATE is the action used for generating and inserting data into the database, whereas UPDATE is used for changing the existing data. A CRUD (Create, Read, Update, and Delete) is an acronym for database operations to enable the storage and management of data.
It is a standard and widely recognized method of performing database operations. The CREATE action involves adding a new item to the database, which is what happens when a new delivery of goods arrives. This operation stores new data in the database to allow the records to be retrieved when required. Similarly, the UPDATE operation allows the records in the database to be updated if new information becomes available or data errors occur. Therefore, the CREATE and UPDATE actions from the CRUD method should be used to describe the required data usage in the case of the function name "Take delivery of new goods" for the entity types GOODS and DELIVERY.

Resize the Hash Table
Determine the positions of the following keys in a hash table of size N = 5 and insert them into the hash table. Resolve collisions by linear probing. Resize the table when the load factor is ≥ 0.5. Draw the hash table.
Keys: 43, 47, 87, 35, 85
When resizing, note that N will change (Hint: the first few prime numbers are 2,3,5,7,11,13,17,19,23).
What is the new N ?
Draw the new hash table, and insert the keys into the hash table. Resolve collisions by linear probing.
Given the keys: 43, 47, 87, 35, and 85, and the size of the hash table N = 5.Hash Function used for calculating the position of the key in the hash table is given by, h(k) = k mod N. Using this formula, we can find out the position of the given keys.
Position of 43 = 43 mod 5 = 3 Position of 47 = 47 mod 5 = 2 Position of 87 = 87 mod 5 = 2 (Collision with 47)Position of 35 = 35 mod 5 = 0Position of 85 = 85 mod 5 = 0 (Collision with 35)We will resolve the collisions by using linear probing. Therefore, we will move in the forward direction from the current position until the first empty position is found.
The new positions of the keys will be:43 → 3, 47 → 2, 87 → 4, 35 → 0, 85 → 1Load Factor = Number of keys / Size of Hash Table= 5 / 5 = 1.0Since the load factor is greater than or equal to 0.5, we will resize the hash table to the next prime number. The next prime number after 5 is 7. Hence, the new size of the hash table will be 7.Draw the new hash table and insert the keys:Position of 43 = 43 mod 7 = 1Position of 47 = 47 mod 7 = 5Position of 87 = 87 mod 7 = 2Position of 35 = 35 mod 7 = 0Position of 85 = 85 mod 7 = 1 (Collision with 43)The new positions after linear probing are:43 → 1, 47 → 5, 87 → 2, 35 → 0, 85 → 3The new hash table after resizing is as follows:Therefore, the new value of N is 7.

You want to modify the design of an IC to permit scan testing. How many additional pins need to be added to the IC?
To enable scan testing in an integrated circuit (IC), additional pins known as scan pins or scan chains are required. The number of additional pins needed depends on the size and complexity of the IC design.
In general, each scan chain requires two additional pins: one for the scan input (SI) and one for the scan output (SO). The SI pin is used to shift in test patterns into the flip-flops in the scan chain, while the SO pin is used to shift out the observed values during testing.
The number of scan chains required in the IC depends on the number of flip-flops or registers that need to be tested simultaneously. Each scan chain typically consists of a series of flip-flops connected in a chain-like fashion.
Therefore, the total number of additional pins needed for scan testing can be calculated by multiplying the number of scan chains by 2 (SI and SO pins).
The specific number of scan chains and, consequently, the additional pins required will vary depending on the design and testing requirements of the IC.

If you had to choose Subjective Relativism ethical theory presented in this unit and use it for all your personal ethical decision making, provide an example situation where you would implement it. How would you respond to the arguments raised against the theory you have chosen?
Subjective relativism ethical theory is the idea that morality is determined by individual beliefs or cultural practices and that there is no objective moral truth. This means that people are free to decide for themselves what is right and wrong based on their own personal beliefs and values. For instance, if someone were to choose Subjective Relativism ethical theory for all their personal ethical decision making, a situation in which they might implement it is as follows: If a vegetarian believes that killing animals is morally wrong and decides not to eat meat, this would be an example of subjective relativism.
For that person, the action of killing animals is wrong because of their personal beliefs and values, which are shaped by their experiences and cultural background. Therefore, they would make a personal ethical decision to avoid eating meat, even if it is considered morally acceptable by others or the norm in their culture.However, the theory of subjective relativism has been criticized by many philosophers. Some argue that it leads to moral relativism, which implies that there is no objective moral truth and that anything goes. Others argue that it can lead to moral nihilism, which is the idea that there are no moral values or standards at all. Additionally, some argue that it does not provide a basis for resolving moral conflicts or dilemmas as it is subjective.
To respond to these arguments raised against subjective relativism ethical theory, it can be argued that moral relativism and moral nihilism are not necessarily the logical conclusions of subjective relativism. Instead, subjective relativism acknowledges that morality is subjective and varies from person to person or culture to culture, but it does not necessarily imply that there are no objective moral standards. Additionally, it can be argued that subjective relativism does provide a basis for resolving moral conflicts as it acknowledges that people have different moral values and beliefs and that these should be respected and taken into account in decision making.

Why is it important to use only the training set to identify the features to be dropped? Explain how stable machine learning libraries such as scikit-learn facilitate this.
When dealing with data sets, it is crucial to split the dataset into training and test sets. This is important for machine learning models because the performance of the model on unseen data is usually the objective.To make sure that the model learns from the data in the best possible way, it is critical to use only the training data to identify the features to be dropped. This is because the test set is used to evaluate the model's ability to generalize, and using the test set for feature selection would introduce data leakage.
This means that the model will have access to information from the test set, and it may be overfitted or biased toward the test data.The scikit-learn library provides several tools that make feature selection and model training a straightforward process. The library implements a variety of feature selection techniques, such as Recursive Feature Elimination (RFE), SelectKBest, and SelectPercentile, that can be used to reduce the dimensionality of the data. These methods work by ranking the features based on some criteria, such as mutual information or correlation, and then selecting the top-ranked features.Another feature of scikit-learn that aids in the stability of machine learning models is cross-validation.
Cross-validation allows the model's performance to be evaluated using multiple train-test splits of the data, reducing the risk of overfitting to a particular training set. It also aids in the selection of the best model hyperparameters by comparing the model's performance across different parameter combinations.In conclusion, the use of only the training set for feature selection is critical to ensure that the machine learning model learns to generalize and does not overfit the data. The scikit-learn library provides tools such as feature selection techniques and cross-validation to aid in the stability of machine learning models.

b[1]++; } void q3 (int *a, int *b) {
int temp *a; a = b;

Given the code, we need to explain what is happening in the code and what are the outcomes. Let us see what is happening in the code:CODE: #include //Prototypesvoid ql (int a, int b);void q2 (int a[], int b[ ]);void q3 (int *a, int *b);int main() { //20051XYZT .
First, we need to initialize the values of X, Y, Z, and T. We will replace these values with their respective values. After that, we create two arrays of integers a and b, which will have 2 values each. Let's say X=2, Y=4, Z=6, and T=8. The a array will contain 2,4 and the b array will contain 6,8. Now, we will call the ql function with arguments a[0], b[1]. The values of a[0] and b[1] are 2 and 8, respectively. The function will execute and the value of a will be updated based on the conditions. Since the value of a[0] is even (2), the value of a will be b, i.e., 8. Now, the value of b will be changed to the previous value of a, which is 2.
So now, a will be 8 and b will be 2. Next, we call the function q2 with arguments a and b. The function q2 will also execute and update the values of a and b accordingly. In the end, it will update the value of b[1] by incrementing it by 1. The updated values of a and b will be 10 and 3, respectively. After that, we call the function q3 with arguments &b[0] and &a[1]. The function will swap the values of the pointers a and b. So, a will now point to the address of b[0] and b will point to the address of a[1]. This means that a will point to the address of 2 and b will point to the address of 4. Next, we call the function q2 with arguments b and a.

Convert the (0.10000110.00111011100000000000000) which is in IEEE 32-bit floating-point format to the equivalent decimal value? Show your steps. ..notionnaintaneidavo Gamannali kako saman.
Conversion of the (0.10000110.00111011100000000000000) is 19.71875.
Given:
0.10000110. 00111011100000000000000
The IEEE 32 bit floating point representation consists 32-bits which can be separated into 3 sections the sign bit (1st bit) , the exponent section (next 8 bits) and the fractional section (remaining 23 bits).
Sign bit Exponent Fraction
0 10000110 00111011100000000000000
Now to convert the given floating point representation into decimal we need to first convert the fractional part into decimal. The fractional part is converted into a decimal by adding all 2-ns (where n represents the position of the bit in the fractional part.
For example in the above representation 3rd, 4th, 5th, 7th, 8th, and 9th bits are one so the decimal representation of the given fractional part becomes.
fraction = 2-3 + 2-4 + 2-5 + 2-7 + 2-8 + 2-9 = 0.232421875
Now we will convert the exponent part into decimal for that we need to add all 2n (where n is the position of the bit in the exponent part but here the position is reversed to that of the fractional part like the first bit is started from the rightmost bit).
exp = 21 + 22 + 27 = 131
Now the formula to convert the given floating point representation into decimal representation is:
(-1)sign bit x (1 + fraction) x 2exp - 127
Here, the sign bit is the first bit from the left of the floating point number, the fraction is the decimal representation of the fractional part, and the exp is the decimal representation of the exponent part.
Applying the formula we get:
= (-1)0 x (1 + 0.232421875) x 2131-127 = 1.232421875 x 24
= 1.232421875 x 16
= 19.71875

Imagine a small sports equipment supply store approached you to write their sales software, but the two partners could not agree on what exactly the software should do.
Discuss 2 examples of where a project is classified as a risky project.
Explain 2 methods you would use to gather requirements for this project. Provide a rationale to support your response.
The software engineering models introduced in this week's reading that can be used to support the response include Waterfall, Spiral, and Agile. These models are all appropriate for various scenarios, but it is essential to consider the client's needs, project scope, timeline, and budget before deciding which one to use.
In the case of a small sports equipment supply store that approached me to write their sales software, but the two partners could not agree on what the software should do, I would suggest the use of the Agile model. Since the two partners of the sports equipment supply store do not agree on what the software should do, the Agile model allows for changing the scope of the project as development progresses.
The agile model requires that the development team work closely with the stakeholders to prioritize the project's features, ensuring that the most critical ones are delivered first and that everyone involved is on the same page about what the software should accomplish. On the other hand, in projects with vague requirements, there is a risk of misunderstandings and rework, which may increase the cost and extend the timeline for completing the project.

Supply Chain strategy often optimizes supply chain networks for "average" performance. Explain why this is or is not the right approach? Edit View Insert Format Tools Table 12pt Paragraph BIU AQV T²V : When locating facilities in a network, the transportation economies about the potential facility location should be considered. What does this mean with respect to where the facility is located and how the network is configured? Edit View Insert Format Tools Table 12pt Paragraph ✓ B I U AV 2V T²V ⠀
Supply Chain strategy is essential in every organization that involves the planning and management of all activities involved in sourcing, procurement, conversion, and logistics. In doing so, the goal is to optimize supply chain networks for average performance.
It is the right approach to optimize supply chain networks for "average" performance because it helps the company attain its objectives and improve its performance. It makes the planning and management of activities in sourcing, procurement, conversion, and logistics more efficient by making use of resources at an optimal level. Also, this approach allows the company to maintain the right balance between supply and demand by producing enough products to meet the customers' demands. By doing so, the company reduces costs, increases efficiency, and enhances customer satisfaction. However, sometimes, optimizing supply chain networks for "average" performance may not be the right approach. This is because customers' preferences are not average. Also, different customers have different needs. Thus, optimizing the supply chain for an average performance level may result in dissatisfied customers who may opt to seek services from the competitors. Thus, it is essential to ensure that the optimization strategy considers the customers' needs and preferences, and a balance is achieved. In conclusion, optimizing the supply chain for average performance is the right approach in most cases. However, this approach should consider the customers' needs and preferences to achieve a balance between supply and demand. Therefore, when locating facilities in a network, transportation economies about the potential facility location should be considered. This means that the facility should be located in an area that is easily accessible to transportation. Additionally, the network should be configured in such a way that the facility is linked to other facilities in the supply chain network to allow for efficient transportation.

a star graph algorithm on qt for the enemy to follow the player in the shortest path
To implement the A* (A-star) graph algorithm in Qt for an enemy to follow the player in the shortest path, you can follow these steps:
Create a graph representation of the game environment, with nodes representing positions and edges representing possible connections between positions.
Assign a heuristic value to each node that estimates the distance between that node and the player's position. This heuristic value helps guide the algorithm towards the player by favoring nodes that are closer to the player.
Implement the A* algorithm to find the shortest path from the enemy's current position to the player's position. The algorithm explores nodes based on their estimated cost, which combines the actual cost to reach a node and the heuristic value.
Use Qt's graphics capabilities to visualize the enemy's movement along the determined shortest path. You can update the enemy's position at each step and redraw the scene accordingly.
Continuously update the enemy's path and position based on the player's movements or changes in the game environment.
By implementing the A* algorithm in Qt, the enemy will intelligently navigate through the game environment, following the shortest path to reach the player's position, taking into account both the actual cost of movement and the heuristic estimate of distance to the player.
