When casting o to s in string d = (string)o, the contents of o are not changed. Casting simply creates a new variable of a different type, but it does not alter the original variable or its contents.The line d = (string)o is performing an explicit type cast, where o is being cast from its original type to a string. The cast is based on the assumption that the object o is of a type that can be successfully converted to a string. The resulting value is then assigned to the variable d.The contents of o itself are not modified during the cast. The cast only creates a new instance of a string object with the converted value from o and assigns it to d. The original value and state of o remain unchanged.

To find the probability that the sample proportion will be within ±0.04 of the population proportion experiencing click fraud, we need to calculate the margin of error.

The margin of error is given by the formula:
Margin of Error = z * sqrt((p * (1-p)) / n)

Where:
- z is the z-score corresponding to the desired level of confidence (typically 1.96 for a 95% confidence level)
- p is the estimated population proportion experiencing click fraud (0.40 in this case)
- n is the sample size (360 in this case)

Calculating the margin of error:
Margin of Error = 1.96 * sqrt((0.40 * (1-0.40)) / 360)
Margin of Error ≈ 0.0359

The probability that the sample proportion will be within ±0.04 of the population proportion experiencing click fraud can be calculated as the sum of the probabilities within the range p ± margin of error.

P(p - 0.04 ≤ sample proportion ≤ p + 0.04) = P(p - 0.04 ≤ sample proportion) - P(p + 0.04 < sample proportion)
Using the standard normal distribution, we can calculate these probabilities.
P(p - 0.04 ≤ sample proportion) = P(z ≤ (sample proportion - p) / sqrt((p * (1-p)) / n))
P(p + 0.04 < sample proportion) = P(z ≤ (sample proportion - p) / sqrt((p * (1-p)) / n))
We use the z-score formula to convert the sample proportion into a standard normal distribution.

Explanation:

(target - 10 ≤ score) AND (score ≤ target + 10).

A logical assertion that can only be TRUE or FALSE is known as a Boolean expression. As long as both sides of the expression have the same fundamental data type, boolean expressions can compare data of any kind.

Oracle OLAP evaluates this expression by comparing each value of the variable actual to the fixed value 20,000.

Unless parentheses indicate a different evaluation order, operators with equal priorities are evaluated from left to right. When the truth value has been determined, the evaluation is stopped.

Answer:

A: Radio waves.

Explanation:

Computers use short-wave radio in order to communicate with devices in it's immediate vicinity.

Using a set, the program stores exclude words and counts their occurrences from user input, displaying the occurrence count of each exclude word.

An example in C++ that demonstrates the usage of a set to store a list of exclude words, reads lines from the user input, and counts the occurrences of each exclude word that the user types:

```cpp

#include <iostream>

#include <string>

#include <set>

#include <map>

int main() {

   std::set<std::string> excludeWords = { "apple", "banana", "orange" };

   std::map<std::string, int> wordCount;

   std::string line;

   std::cout << "Enter lines of text (press 'q' to quit):\n";

   while (std::getline(std::cin, line) && line != "q") {

       std::string word;

       std::istringstream iss(line);

       while (iss >> word) {

           if (excludeWords.count(word)) {

               wordCount[word]++;

           }

       }

   }

   std::cout << "\nOccurrence count of exclude words:\n";

   for (const auto& pair : wordCount) {

       std::cout << pair.first << ": " << pair.second << std::endl;

   }

   return 0;

}

```

In this example, we define a set called `excludeWords` that stores the list of exclude words. We also define a map called `wordCount` to store the count of each exclude word that the user types.

The program prompts the user to enter lines of text until they enter 'q' to quit. It then reads each line and splits it into individual words. For each word, it checks if it exists in the `excludeWords` set. If it does, it increments the count in the `wordCount` map.

Finally, the program displays the occurrence count of each exclude word that the user typed.

Note: Don't forget to include the necessary header files (`<iostream>`, `<string>`, `<set>`, `<map>`, `<sstream>`) and use the `std` namespace or specify the namespace for each standard library object used.

Answer:

Data that adds up to 100%

Explanation:

i) Protocol without Acks:

In a protocol without acknowledgments, the amount of "data in flight" refers to the maximum amount of data that can be transmitted over the network without waiting for acknowledgments. It is determined by the bandwidth-delay product, which is calculated by multiplying the bandwidth (10 Mbps) by the round-trip time (RTT) or latency (10 minutes).

To convert the latency from minutes to seconds, we multiply by 60:

Latency = 10 minutes * 60 seconds/minute = 600 seconds

Data in Flight = Bandwidth * Latency

Data in Flight = 10 Mbps * 600 seconds = 6,000 megabits or 750 megabytes

ii) Protocol with Acks:

In a protocol with acknowledgments, the amount of "data in flight" is typically limited by the receiver's advertised window size. This represents the maximum amount of unacknowledged data that the receiver is willing to accept.

The usefulness of the data-in-flight is to ensure efficient utilization of the available bandwidth. By maintaining a certain amount of data in flight, the sender can keep the link fully utilized without waiting for acknowledgments. This helps to achieve higher throughput and minimize the impact of latency. However, it is important to strike a balance between the amount of data in flight and the available network resources to avoid congestion and ensure reliable delivery of data.

Since "zebra" comes after "orange" alphabetically, the search continues amongst the second half of the list.

The centermost item on this narrowed down list proves to be "tent", from there, it is deduced that "zebra" must go after "tent" alphanumerically.

Likewise, the process is repeated for the reminder of the sequence.

Little's Law states that the average number of customers in a stable system is equal to the average arrival rate multiplied by the average time each customer spends in the system.

While it is true that the amount of data requests a computer server receives may fluctuate throughout the day, Little's Law still applies as long as the system is stable. However, the parameters of the system, such as the arrival rate and the service time, may vary over time, and this may affect the performance of the system.

Determining that a person is who he or she claims to be on a computer is called authentication.

Authentication is a crucial aspect of cybersecurity, as it helps maintain the confidentiality, integrity, and availability of information and systems. There are various methods used to authenticate users, such as passwords, tokens, and biometrics.

Passwords are the most common authentication method, requiring the user to enter a secret string of characters known only to them. Tokens, on the other hand, are physical devices that generate unique codes or utilize a digital certificate to confirm the user's identity. Biometrics, such as fingerprint or facial recognition, rely on unique physical characteristics of the user to verify their identity.

Two-factor authentication (2FA) is an enhanced security measure that requires the user to provide two separate forms of identification, such as a password and a one-time code sent to their mobile device. This added layer of security helps protect against unauthorized access, even if one of the authentication methods has been compromised. In conclusion, authentication is essential for safeguarding information and ensuring that only authorized individuals can access sensitive data or systems.
