Answer:

A. The most secure email message authenticity and confidentiality is provided by signing the message using the sender’s public key and encrypting the message using the receiver’s private key

Explanation:

Public key cryptography helps to send public key in an open and an insecure channel as having a friend's public key helps to encrypt messages to them.

The private key helps to decrypt messages encrypted to you by the other person.

The most secure email message authenticity and confidentiality is provided by signing the message using the sender’s public key and encrypting the message using the receiver’s private key

Explanation:

See attached images for the program and sample output

This answer includes a Python program to help Linda calculate the required markup for her business. It ensures she achieves her desired 10% net profit after all expenses and a 15% sale discount.

To calculate the markup percentage Linda needs in her cosmetic and clothing business, we have to account for all her expenses (merchandise cost, store rent, employees' salary, electricity cost) and her desired profit margin. Here is a Python program to help Linda determine the required markup-

def calculate_markup(total_merchandise_cost, salary, yearly_rent, electricity_cost):

  total_expenses = total_merchandise_cost + salary + yearly_rent + electricity_cost

  desired_profit = 0.10 × total_merchandise_cost  # 10% of merchandise cost

  sales_needed = total_expenses + desired_profit

  # When the item has to be sold at a 15% discount

  selling_price_after_discount = sales_needed / (1 - 0.15)  # reverse engineering the discount

  # Markup percentage calculation

  markup = (selling_price_after_discount - total_merchandise_cost) / total_merchandise_cost * 100

  return markup

# Example usage

merchandise_cost = float(input('Enter the total cost of the merchandise: '))

salary = float(input("Enter the salary of the employees (including her own salary): "))

yearly_rent = float(input("Enter the yearly rent: "))

electricity_cost = float(input("Enter the estimated electricity cost: "))

markup_percentage = calculate_markup(merchandise_cost, salary, yearly_rent, electricity_cost)

print(f'The merchandise should be marked up by approximately {markup_percentage:.2f}% to achieve the desired profit.')

This program calculates the total expenses, adds the desired profit, adjusts for the 15% discount and then calculates the necessary markup.

A vital mission program is necessary for an organization's life. If a critical task program disrupted, industrial control should be severely affected.  The essential support device is often referred to as critical task equipment.

Safety system for nuclear reactors-

The nuclear power plant is used to control the system, and it also contains and continues reactions.  It's also usually used only for energy production, and also used experiments and clinical isotope manufacture.  

If another system of nuclear power fails, this could result in a continuous nuclear reaction in a range of aspects like irradiated leaks. These same persons across the area may experience serious radioactivity symptoms.

The main task in their personal life-  

They realize, that without power, they turn down your entire life when you've never encountered a dark off with more than 30 minutes. Essentially, people wouldn't have been allowed to do what you'll do, entirely frozen.

Answer:

A. Social network analysis (SNA).

Explanation:

This is explained to be a process of quantitative and qualitative analysis of a social network. It measures and maps the flow of relationships and relationship changes between knowledge possessing entities. Simple and complex entities include websites, computers, animals, humans, groups, organizations and nations.

The SNA structure is made up of node entities, such as humans, and ties, such as relationships. The advent of modern thought and computing facilitated a gradual evolution of the social networking concept in the form of highly complex, graphical based networks with many types of nodes and ties. These networks are the key to procedures and initiatives involving problem solving, administration and operations.

Explanation:

A software warranty is a written promise or guarantee from a software manufacturer or company to repair or replace a product of it has a fault within a particular period of time. Such faults must arise from the manufacturer's errors.

During the warranty period given, the software developer must fix all the defects and bugs within the software so long as it occurred due to a development fault and there is evidence of system failure.

Some software programs and applications really do require a warranty with a longer duration. Such softwares include those used in big businesses and corporations like banks, medical softwares, nuclear softwares and aviation softwares. The warranties are like a testament of reliability of the software in such critical and delicate sectors.

An open source software for a video game may not require a warranty or the warranty period might not be long compared to business softwares.

Answer:

a) Time to live field

b) Destination

c) Yes, they have two ip addresses.

d) 128 bits

e) 32 hexadecimal digits

Explanation:

a) the time to live field (TTL) indicates how long a packet can survive in a network and whether the packet should be discarded. The TTL is filled to limit the number of packets passing through N routers.

b) When a large datagram is fragmented into multiple smaller datagrams, they are reassembled at the destination into a single large datagram before beung passed to the next layer.

c) Yes, each router has a unique IP address that can be used to identify it. Each router has two IP addresses, each assigned to the wide area network interface and the local area network interface.

d) IPv6 addresses are represented by eight our characters hexadecimal numbers. Each hexadecimal number have 16 bits making a total of 128 bits (8 × 16)  

e) IPv6 address has 32 hexadecimal digits with 4 bits/hex digit

The TCP/IP concepts of packet forwarding, fragmentation, and reassembly along with IPv4 and IPv6 addressing schemes are explained.

TTL (Time To Live) field in the IPv4 datagram header can be used to ensure that a packet is forwarded through no more than N routers. When a large datagram is fragmented into multiple smaller datagrams, these smaller datagrams are reassembled into a single larger datagram at the destination host. Routers do have IP addresses, typically one per interface, so the number varies. IPv6 addresses consist of 128 bits; represented using hexadecimal digits (each 4 bits), hence we need 32 hexadecimal digits to represent an IPv6 address.

Explanation:

That's the code and it is done with the program in c++ according to instructions given in the question using binary search. It can guess the correct number in 10 or fewer attempts and also shows the number of attempts it took to guess the number.

​ #include <iostream> using namespace std; int guess() { string input; int l = 1, h = 1000; int mid = (l + h) / 2, count = 0; while (1) { //count the number of attemts to guess the number ++count; //cout << count << "\n"; cout << "\n"; cout << "Is " << mid << " correct? (y/n): "; cin >> input; //if input is y print the guessed no. and return if (input == "y") { cout << mid << " guessed in " << count << " attempts!\n"; return 1; } //if input is n ask the user if it's higher or lower than current guess if (input == "n") { cout << "Is the number greater than or less than the number ? (h/l): "; cin >> input; } //if input is higher assign mid incremented by 1 to low //else decrement mid by 1 and assign to high if (input == "h") l = mid + 1; else h = mid - 1; //calculate mid again according to input by user again mid = (l + h) / 2; } } int main() { cout << "****WELCOME TO THE GUESS THE NUMBER GAME!****\n"; cout << "Guess any number between 1 to 1000.\n"; cout << "This game depends on user giving correct answers and not changing their number middle of game.\n"; guess(); } ​

The provided C++ program reads two strings, calls the `split` function using the given header, and prints the resulting vector with elements separated by commas.

Below is an updated C++ program that adheres to the given header and meets the specified requirements. It reads two strings, calls the `split` function, and prints the resulting vector:

#include <iostream>

#include <vector>

#include <string>

// Function to split a string by a delimiter

std::vector<std::string> split(std::string target, std::string delimiter) {

   std::vector<std::string> substrings;

   size_t start = 0;

   size_t end = target.find(delimiter);

   while (end != std::string::npos) {

       substrings.push_back(target.substr(start, end - start));

       start = end + delimiter.length();

       end = target.find(delimiter, start);

   }

   substrings.push_back(target.substr(start));

   return substrings;

}

int main() {

   std::string inputString, delimiter;

   std::cout << "Enter string to split: ";

   std::getline(std::cin, inputString);

   std::cout << "Enter delimiter string: ";

   std::getline(std::cin, delimiter);

   // Call the split function

   std::vector<std::string> result = split(inputString, delimiter);

   // Print the resulting vector

   std::cout << "The substrings are: ";

   for (size_t i = 0; i < result.size(); ++i) {

       std::cout << "\"" << result[i] << "\"";

       if (i < result.size() - 1) {

           std::cout << ", ";

       }

   }

   return 0;

}

This program uses the `split` function to tokenize the input string based on the given delimiter, and it prints the resulting vector as required.

Answer:

The require number of acres is between 220714.991 acres and 4414287.982 acres

Explanation:

Given

Power = 4,000MW

Yield = 10,000lb - 20,000 lb/year

Electricity Efficiency = 35%

Required

Number of acres needed

To calculate the required number of acres, the following steps will be followed.

1. Calculate total energy

2. Calculate the intensity of energy

3. Calculate number of acres.

Calculating the total energy

Energy = Power * Time

From the question;

Power = 4,000MW

The crop yield is measured on a yearly basis. So, time = 1 year.

Convert time to seconds.

First, we convert to days

1 year = 365 days;

Then to hours

= 365 * 24

Then to minutes

= 365 * 24 * 60

Then to seconds

= 365 * 24 * 60 * 60

So,

1 year = 365 * 24 * 60 * 60

1 year = 31,536,000s.

Energy = 4,000 MW * 31,536,000

Emergy = 1.26144E11 MJ

Calculating the intensity of energy.

Energy Intensity = Required Energy * Efficiency

Efficiency = 35%

Calculating Required Energy

When Yield = 10,000 lb

First, we convert this to kilogram

1 lb = 0.453592 kg

10,000 lb = 10,000 * 0.453592

10,000 lb = 4535.92 kg

From energy characterisation factors and method table.

1 kg requires 18 MJ of energy.

4535.92 will require:

4535.92 * 18MJ

= 81646.56 MJ of energy.

Hence, Required Energy = 81646.56 MJ

So, Energy Intensity = 81646.56 MJ * 35%

Energy Intensity = 28576.296 MJ.

Hence, when yield = 10,000 lb; the energy intensity is 28576.296 MJ

When Yield = 20,000 lb

Energy Intensity = Required Energy * Efficiency

If the energy intensity is 28576.296 MJ when yield = 10,000 MJ

Energy Intensity = 2 * 28576.296 MJ

Yield = 2 * 10,000 lb

Hence, Energy Intensity = 2 *28576.296 MJ

Energy Intensity = 57152.592 MJ

Now, the number of acres can be calculated.

Number of acres = Total Energy ÷ Intensity.

Total Energy = 1.26144E11 MJ

When Yield = 10,000 lb, Intensity = 28576.296 MJ

Number of acres = 1.26144E11 ÷ 28576.296

Number of acres = 4414287.982 acres

When Yield = 20,000 lb, Intensity = 57152.592 MJ

Number of acres = 1.26144E11 ÷ 57152.592

Number of acres = 220714.991 acres

Hence, the require number of acres is between 220714.991 acres and 4414287.982 acres

Explanation:

#include <iostream>

#include <fstream>

using namespace std;

int main()

{

int size = 10;

string inputFileName, outputFileName;

cout << "Please enter input file name, including full path: ";

cin >> inputFileName;

cout << "Please enter output file name, including full path: ";

cin >> outputFileName;

ifstream inFile(inputFileName.c_str());

ofstream outFile(outputFileName.c_str());

// checking whether input and output files are good to open

if(!inFile.is_open())

{

cout << "Cannot open " << inputFileName << endl;

exit(EXIT_FAILURE);

}

if(!outFile.is_open())

{

cout << "Cannot open " << outputFileName << endl;

exit(EXIT_FAILURE);

}

// declare an array of string to store 1024 words

string words[size];

// read the file for exactly 1024 words

// assuming each line of input file contains only 1 word

int count = 0;

string word;

while(getline(inFile, word))

{

if(count == size)

break;

words[count++] = word;

}

inFile.close();

// now we need to print the words array in reverse order both to the console and to the output file, simultaneously

cout << "WORDS:\n------\n";

for(int i = size - 1; i >= 0; i--)

{

if(words[i] != "")

{

cout << words[i] << endl;

outFile << words[i] << endl;

}

}

outFile.close();

system("pause");

return 0;

}

Final answer:

The question is about creating a program for file reading and writing, including array manipulation and outputting content in reverse. The program must handle input/output operations, file size variations, and ensure resource management by closing files properly.

Explanation:

The student's question pertains to writing a program that can read and write files, and specifically handle reading words into an array and then outputting them in reverse order to a file and the screen. The steps to achieve this involve prompting the user for file paths, checking the success of opening files, handling files of various sizes, and managing resources correctly by closing files. A 'pause' before the program ends is also required, likely to allow the user to see the output before the program closes.

To begin, here's a simplified pseudo-code outline:

Note: When implementing the read operation, the program should consider the file size which may be larger than the array and handle it appropriately, perhaps by reading in chunks if necessary.

1.) asking clarifying questions, without interrupting

2.) keeping eye contact

Answer:

Because reusing the old passwords possess security threats.

Explanation:

A password can be defined as a string of characters or words or phrases that are used to authenticate the identity of the user. It is also known as passcode and should be kept confidential. A password is used to access constricted systems, applications, etc.

A password or passcode is usually composed of alphabets, numbers, symbols, characters, alphanumeric, or a combination of these.

In the given case, Judy was not able to change her passcode to the previous one because reusing old passwords is prohibited in any sites or systems. A system denies the user to reuse the old passwords for various reasons but most importantly due to security reasons. Though it is said that old passwords can be used after 100 times but seldom someone changes a password that much. All systems care for the security of their users thus they deny reusing old passcodes.

Answer:

Option D 0 <= index < phrase.length() - key.length()

Explanation:

The index has to be between the range of 0 <= index < phrase length - key length to prevent index out of bound error. This is because the substring method will have to extract part of the string with a certain length from the original string starting from the index-position. If the key length is longer than the string area between phrase[index] and  phase.length(), an index out of bound runtime error will be thrown.

Answer:

a.

No, it will not affect the speedup obtained from pipe lining.

b.

Yes,it will affect.

Speedup time can be calculated as; 850 / 250 = 3.4

Final answer:

The question is about adding functionality to a computer program to display monthly and yearly earnings for Marian Basting's sewing jobs. This involves data handling, control structures, and algorithms to manage and total earnings in the generated report.

Explanation:

The question pertains to modifying a computer program for Marian Basting, who takes in sewing jobs and tracks them in two sorted files. The program should not only merge the files to produce a date-ordered report of all Marian's jobs for the year but should also be modified to display total earnings at the end of each month and the yearly total earnings. To achieve this, the program would require additional functionality to sum the price of jobs, categorized by month and then aggregated for the year-end total. This could involve processing each entry, keeping a running total, and then displaying the totals when a new month starts or the report ends.

For clarity, here's a hypothetical implementation outline: Load the entries from both files, sort them by date, iterate through the sorted list while maintaining a subtotal for each month's earnings. After processing all entries for a month, display the subtotal. Upon reaching year-end, display the final total. This implementation requires knowledge of programming concepts such as data handling, control structures, and algorithms for sorting and totaling.

This response examines the role of smartphones, laptops, and GPS devices in daily life, considering how they affect communication, work, travel, and convenience.

Explanation:

Understanding how electronic devices shape our daily lives can provide insight into their pervasive influence and the reliance we've developed on technology. For this exercise, we'll examine three common devices: a smartphone, a laptop, and a GPS device.

Smartphones have become nearly indispensable in modern life. They serve as communication hubs, personal assistants, and portable entertainment systems. The smartphone keeps us connected through calls, texts, emails, and social media. It also helps manage our schedules, set alarms, and capture memories through its camera. Life without smartphones would mean a return to separate devices for each of these functions and a significant loss in convenience and efficiency.

Laptops offer portable computing power that enables us to work, learn, and play from virtually anywhere. They are essential for students and professionals alike, as they support software for creating documents, managing data, and facilitating online meetings. The absence of laptops would drastically change the landscape of mobile work and education, likely requiring a heavier reliance on desktop computers and physical media.

A GPS device provides accurate navigation and location tracking, which is especially useful for travel and logistics. The utility of GPS extends beyond simple navigation to include applications in science, military, and emergency services. Without GPS technology, we would need to rely on physical maps and alternative methods for location tracking, potentially complicating travel and critical operations.
