The result of the addition of 76 and 3A in hexadecimal notation is B0.
Therefore, the answer is C) B0.

To perform the addition of two hexadecimal numbers, we first write down the numbers and align them by their place value. Then, we add the numbers column by column, starting from the rightmost column. If the sum of two digits is greater than or equal to 16, we carry over the value of 1 to the next column. In this case, 6 plus A is equal to 10, which is represented as A in hexadecimal. The carry-over value of 1 is added to 7 to get 8, and then we add the two remaining digits of 0 and 3 to get B0. The sum comes out to be B0.

One strategy for managing debilitative communication apprehension is to engage in systematic desensitization.

This technique involves gradually exposing oneself to feared situations or stimuli in a safe and controlled environment, while learning to manage feelings of anxiety or discomfort. For example, someone who experiences anxiety when speaking in public might begin by practicing their speech in front of a trusted friend or family member, then gradually work their way up to larger groups or more challenging speaking situations. Along the way, they can use relaxation techniques, such as deep breathing or visualization, to manage their anxiety. By gradually exposing oneself to feared situations and learning to manage feelings of anxiety, systematic desensitization can help individuals to overcome debilitative communication apprehension and improve their confidence and communication skills.

The time complexity for the given code can be determined as follows:

The first while loop has a time complexity of log n. The second while loop has a time complexity of log n. And the third while loop has a time complexity of n/2. The explanation for the third while loop's time complexity is given below:

Explanation:

While calculating the time complexity of the third while loop (k < n), we need to consider how many times this loop will run. The loop will run from k = 1 to k = n/2. So, the time complexity of the third while loop will be n/2. This is because the value of k will range from 1 to n/2. The loop will run n/2 times. Therefore, the time complexity of the third loop will be n/2.

To summarize, the time complexity of the first while loop is log n, the time complexity of the second while loop is log n, and the time complexity of the third while loop is n/2.

Mutual authentication can prevent the Man-in-the-middle attack.

Mutual authentication is a security mechanism where both parties involved in a communication exchange authenticate each other's identities before sharing any sensitive information. This process helps to prevent unauthorized access and eavesdropping, and it can be particularly useful in wireless communication scenarios where the wireless medium can be susceptible to attacks.

One type of attack that mutual authentication can prevent is a man-in-the-middle (MITM) attack. In an MITM attack, an attacker intercepts and alters communication between two parties, making it appear as though each is communicating with the other while actually controlling the communication. Mutual authentication can prevent an MITM attack by ensuring that both parties verify each other's identities before sharing any sensitive information.

Therefore, the correct answer to the question is C, Man-in-the-middle. Mutual authentication does not directly prevent wireless IP spoofing, wireless sniffing, or wireless poisoning attacks, although it can provide an additional layer of security against them.

In concurrent programming, a semaphore is a synchronization primitive used to control access to a shared resource.

It can be initialized with a value that represents the maximum number of concurrent threads allowed to access the resource. When a thread wants to access the resource, it must acquire the semaphore, which decrements its value. If the value becomes zero, indicating that the maximum number of threads is already accessing the resource, the thread will be blocked until another thread releases the semaphore, increasing its value. This mechanism ensures that the resource is accessed in a controlled manner, preventing race conditions and allowing for efficient coordination among multiple threads.

The DHCP settings in a Windows computer's network interface are labeled as "Obtain an IP address automatically" and "Automatic addressing".

These labels refer to the process of automatically acquiring an IP address from a DHCP server.

When a Windows computer is set to "Obtain an IP address automatically", it sends a request to the network for an IP address.

The DHCP server then responds with an available IP address, along with other network settings such as the default gateway and DNS server information. The computer then configures its network interface with the assigned IP address and settings.

Similarly, the label "Automatic addressing" refers to the process of obtaining network settings such as the IP address, subnet mask, and default gateway automatically from a DHCP server.

The "$" symbol represents the end of a line, which ensures that the string ends with "y".

"g" matches the literal character "g" at the beginning of the string.

The 4-bit two's complement representation of the operation (7 - 5) is "0010."

To understand this representation, we need to consider the two's complement representation of the numbers involved. In a 4-bit system, the range of two's complement numbers is -8 to +7.

To find the two's complement of a positive number, we can simply represent the magnitude in binary form. For example, the binary representation of 7 is "0111" and the binary representation of 5 is "0101."

To subtract one number from another, we take the two's complement of the subtrahend (5) and add it to the minuend (7). The two's complement of 5 is obtained by inverting the bits and adding 1, resulting in "1011." Adding 7 and -5 (represented as 1011) gives us 12, which in a 4-bit system is "1100." However, since the range is limited to -8 to +7, we take the lower 4 bits, giving us "0010" as the final result.
