VGA display connections typically have 15 pins. The pins are arranged in a specific configuration to ensure that the correct signals are transmitted between the devices.

VGA (Video Graphics Array) is a video display standard that has been widely used for many years. It uses a 15-pin connector to transmit analog video signals between a computer or other video source and a monitor or display device. The VGA connector is typically blue in color and has three rows of five pins each. The pins are arranged in a specific configuration to ensure that the correct signals are transmitted between the devices.

VGA connections are capable of transmitting video signals at resolutions up to 2048x1536 pixels and at refresh rates of up to 85 Hz. However, VGA is an analog signal and is therefore susceptible to interference and degradation over long cable runs. It has largely been replaced by digital display connections such as DVI and HDMI, which offer better image quality and compatibility with modern devices. Nonetheless, VGA remains a popular standard for many legacy systems and displays.

The output of the given Python code fragment is:

24

8

-4

6

The code fragment uses a `for` loop to iterate over the elements of the list `[12, 4, -2, 3]`. In each iteration, the current element `i` is multiplied by 2 using the expression `2 * i`. The result is then printed using the `print()` function.

In the first iteration, `i` is equal to 12, so `2 * 12` results in 24, which is printed. In the second iteration, `i` is 4, so `2 * 4` equals 8, which is printed. In the third iteration, `i` is -2, so `2 * -2` gives -4, which is printed. Finally, in the fourth iteration, `i` is 3, so `2 * 3` results in 6, which is printed.

Answer:

FIN packet

Explanation:

To let the other computer know that it has finished sending data, a FIN (Finish) packet is used. FIN packet is specifically designed to signal the intention to close the TCP connection and indicates that the computer has finished sending data.

In the TCP (Transmission Control Protocol) communication protocol, data is sent in segments between two computers. When one computer wants to terminate the connection and indicate the completion of data transmission, it sends a FIN packet to the other computer. The FIN packet serves as a request to close the TCP connection.

Upon receiving the FIN packet, the receiving computer acknowledges the request by sending an ACK (Acknowledgment) packet back to the sender. This process is known as the TCP connection termination handshake. The receiving computer can also send its own FIN packet to indicate the completion of data transmission from its side.

Once both computers have exchanged FIN and ACK packets, the TCP connection is closed, and both computers are informed that data transmission has been completed.

The question should be:

TCP ACK scans are a valuable tool for probing firewall rules because they allow the scanner to determine whether a particular port is open or closed. Unlike TCP SYN scans, which try to establish a full three-way handshake with the target machine, TCP ACK scans simply send an ACK packet to the target machine.

If the firewall is configured to block incoming ACK packets, the scanner will receive a TCP RST response, indicating that the port is closed. If the firewall allows incoming ACK packets, the scanner will receive no response, indicating that the port is open. TCP ACK scans are default useful for identifying ports that are filtered by a firewall, as they can bypass certain types of filtering that might block SYN scans or XMAS tree scans.

The process being discussed here is called genetic inheritance, which is observed in the offspring produced by crossing two parent organisms. In this case, the parent organisms are two pink snapdragons, and the offspring produced are only pink snapdragons.

Snapdragons exhibit incomplete dominance, a type of inheritance where neither allele is completely dominant over the other. In snapdragons, the red and white alleles are involved in determining flower color. When a red (R) allele and a white (W) allele are present, they produce a pink (RW) snapdragon. When you cross two pink snapdragons (RW x RW), the possible offspring genotypes are RR, RW, and WW. The phenotypes corresponding to these genotypes are red (RR), pink (RW), and white (WW) snapdragons. However, in your question, the cross produces only pink snapdragons, which means both parent snapdragons have the genotype RW, and the offspring inherit one R and one W allele from the parents, resulting in the genotype RW for all offspring. In the case of crossing two pink snapdragons, only pink snapdragons are produced because both parent snapdragons have the genotype RW, which exhibits incomplete dominance. As a result, all offspring inherit one R and one W allele, leading to the pink phenotype in all snapdragon offspring.

The recursive method announce(n) takes an integer n and recursively divides it by 2 until n becomes less than or equal to 1. The output is 2 5 10 20, as stated.

The result of the call `announce(20)` is `2 5 10 20`. The method takes in an integer n and first checks if n is greater than 1. If true, then `announce(n / 2)` is called.

This means the method is called recursively with n / 2 as the new argument. When the recursion is finished, `System.out.println(n)` prints n. What this means is that the recursion starts with 20 as n and it continues until the base case (n ≤ 1) is reached.

The recursive calls work in the following way: Since 20 is greater than 1, the method is called again with `announce(10)`Half of 20 is 10. We then call the method with 10 as the argument.

Next, since 10 is greater than 1, the method is called again with `announce(5)`Half of 10 is 5. We then call the method with 5 as the argument.Next, since 5 is greater than 1, the method is called again with `announce(2)`Half of 5 is 2.

We then call the method with 2 as the argument. Next, since 2 is greater than 1, the method is called again with `announce(1)`Half of 2 is 1. We then call the method with 1 as the argument.Since 1 is not greater than 1, the recursion stops.

Since `announce(1)` is called last, it prints 1 first, followed by 2, 5, 10, and 20, which were all called before it. Therefore, the answer is:Option d. 20 10 5 2 1.

To implement a recursive function in C++ that determines if a number is prime, you can use the provided skeletal code as a starting point. Here's the completed code with the recursive logic:

```cpp

#include <iostream>

using namespace std;

int IsPrime(int testVal, int divVal) {

   // Base case 1: 0 and 1 are not prime, testVal is not prime

   if (testVal == 0 || testVal == 1)

       return 0;

   // Base case 2: testVal only divisible by 1, testVal is prime

   if (divVal == 1)

       return 1;

   // Recursive Case

   // Check if testVal can be evenly divided by divVal

   if (testVal % divVal == 0)

       return 0;

   // If not, recursive call to IsPrime with testVal and (divVal - 1)

   return IsPrime(testVal, divVal - 1);

}

int main() {

   int primeCheckVal = 0; // Value checked for prime

   // Check primes for values 1 to 10

   for (primeCheckVal = 1; primeCheckVal <= 10; ++primeCheckVal) {

       if (IsPrime(primeCheckVal, primeCheckVal - 1) == 1) {

           cout << primeCheckVal << " is prime." << endl;

       }

       else {

           cout << primeCheckVal << " is not prime." << endl;

       }

   }

   return 0;

}

```

The `IsPrime` function takes two arguments: `testVal` (the number to be checked for primality) and `divVal` (the divisor used for checking divisibility). It implements the recursive logic as follows:

- Base Case 1: If `testVal` is 0 or 1, it is not prime, so return 0.

- Base Case 2: If `divVal` reaches 1 (only divisible by 1), it is prime, so return 1.

- Recursive Case: If `testVal` is divisible by `divVal`, return 0. Otherwise, make a recursive call to `IsPrime` with `testVal` and `(divVal - 1)`. The `main` function checks prime numbers for values 1 to 10 using a loop and calls `IsPrime` for each value. The result is then printed accordingly.
