Email attachments from trusted senders and in common formats such as PDF, JPG, and DOCX are generally safe to open.
Email attachments that come from trusted senders, such as friends, colleagues, or known businesses, are less likely to contain malicious code. Common file formats like PDF, JPG, and DOCX are also considered safe since they are not executable and cannot run code on your computer. However, it's still important to exercise caution and ensure that the sender is legitimate before opening any attachments, especially those in less common file formats such as EXE, ZIP, or RAR, which are often used to distribute malware. Additionally, keep your antivirus software up to date and run regular scans to detect and remove any malicious code that may have slipped through.

in this part, we will use malloc() to reduce the memory consumption of our encyclopedia program. copy in your code from the previous part. modify the definition of the encyclopedia so that it contains a pointer to an article, not an array of articles. this pointer will point at a block of memory allocated using malloc(). you will do that allocation in main(). after the user enters how many articles they want to add, call malloc() to allocate the memory for all of those articles. store the pointer to that memory in your encyclopedia. your code might compile and run without a call to malloc(), but it wouldn't be correct, in the same way that accessing out-of-bounds indices of an array is incorrect. some possible effects include segmentation faults, or accidentally modifying some other data the program is using. make any other code updates needed to support this change. as good practice, don't forget to call free() when you're done with the memory - but not before checking the memory consumption! run the program and compare the memory consumption to that of the program from the previous section. it should be much smaller, and it should vary based on the number of articles entered. demo this program to the ta.
In this part, we will modify the encyclopedia program to reduce memory consumption by using malloc(). Instead of defining the encyclopedia as an array of articles, we will change it to a pointer to an article. The memory allocation for the articles will be done in the main() function after the user inputs the desired number of articles.
Here's an outline of the changes to the code:
1. Modify the definition of the encyclopedia to have a pointer to an article, not an array of articles.
2. In the main() function, after the user enters the number of articles they want to add, call malloc() to allocate memory for all of those articles.
3. Store the pointer to that memory in the encyclopedia.
4. Update the rest of the code to support this change.
5. Call free() to release the memory when it's no longer needed, but not before checking the memory consumption.
By using malloc(), the memory consumption of the program will be much smaller, and it will vary based on the number of articles entered. Demonstrating this program to the TA will showcase the improved memory efficiency compared to the previous version.

d. SYN flood attack "
An attack that takes advantage of the procedures for initiating a session is known as d. SYN flood attack.
A SYN flood attack takes advantage of the three-way handshake process that is used to initiate a session between a client and server. During this process, the attacker floods the target server with numerous SYN requests, but never completes the handshake process by sending an ACK response. This causes the server to allocate resources to each request, eventually overwhelming its capacity to handle additional requests and effectively denying service to legitimate clients.
In conclusion, a SYN flood attack is a type of session initiation attack that exploits the fundamental protocols of network communication to disrupt service availability.

the output is:
200 forks

}
};
main.cpp :
#include "InventoryNode.h"
int main() {
int count;
int numItems;
string item;
InventoryNode *headNode = new InventoryNode();
InventoryNode *currNode;
// Obtain number of items

// Get each item and number of each
for (int i = 0; i < count; i++) {

}
// Print linked list
currNode = headNode->GetNext();
while (currNode != NULL) {
currNode->PrintNodeData();
currNode = currNode->GetNext();
}
return 0;
To define an InsertAtFront() member function in the InventoryNode class that inserts items at the front of a linked list (after the dummy head node), we can do the following:
void InsertAtFront(InventoryNode *head, InventoryNode *newNode) { newNode->nextNodeRef = head->nextNodeRef;
head->nextNodeRef = newNode;
]
This function takes two parameters: head is a pointer to the dummy head node, and newNode is a pointer to the new node that we want to insert at the front of the linked list. The function first sets the nextNodeRef pointer of newNode to the current nextNodeRef pointer of the dummy head node (which will be the current first node in the linked list). Then, it sets the nextNodeRef pointer of the dummy head node to point to newNode, effectively inserting newNode at the front of the linked list.

To make the code print "greater than -15" if the value of user_num is greater than -15, we need to use a conditional expression. The conditional expression will check whether the value of user_num is greater than -15 or not. Here's the code that will achieve this:
user_num = int(input()) # Program will be tested with values: -13, -14, -15, -16.
if user_num > -15: # Your code goes here
print('greater than -15')
else:
print('-15 or less')
Explanation: In the code above, we have used the if-else statement to check whether the value of user_num is greater than -15 or not. If the value of user_num is greater than -15, then the code inside the if statement will be executed, which is to print "greater than -15". If the value of user_num is less than or equal to -15, then the code inside the else statement will be executed, which is to print "-15 or less".We have used the greater than operator (>) to check whether the value of user_num is greater than -15. If the condition is true, then the code inside the if statement will be executed, otherwise, the code inside the else statement will be executed.Overall, the code above is a simple example of how to use conditional statements in Python to control the flow of the program based on certain conditions.

2. File-System Management: The operating system provides a file-system structure to organize and manage data on secondary storage devices. This includes creating, modifying, and deleting files and directories, managing file permissions, and ensuring data integrity. The file-system management ensures that files are stored in a way that makes it easy for users and applications to access and manipulate data.
3. Disk Scheduling: When multiple read and write requests are made to secondary storage, the operating system needs to determine the order in which these requests are processed. Disk scheduling algorithms, such as First-Come, First-Served (FCFS), Shortest Seek Time First (SSTF), or the Elevator algorithm, are used to optimize the response time and minimize the overall movement of the read/write head. This reduces the latency and improves the performance of the storage subsystem.
In summary, the operating system plays a crucial role in managing secondary-storage devices by handling space allocation, maintaining file-system structures, and optimizing disk access through scheduling algorithms. These activities ensure efficient utilization and access to data stored on secondary storage devices.
