Suppose a program must execute 1012 instructions to solve a particular problem. Suppose further that a single processor system can solve the problem in 106 seconds. So, on average, the single processor system executes 106 instructions per second. Now suppose that the program has been parallelized for execution on a distributed-memory system. Suppose also that if the parallel program uses p processors, each processor will execute 1012/p instructions and each processor must send 109(p-1) messages. Finally, suppose that there is no additional overhead in executing the parallel program. That is, the program will complete after each processor has executed all of its instructions and sent all of its messages, and there won’t be any delays due to things such as waiting for messages.
a. Suppose it takes 10-9 seconds to send a message. How long will it take the program to run with 100 processors, if each processor is as fast as the single processor on which the serial program was run?
b. Suppose it takes 10-3 seconds to send a message. How long will it take the program to run with 100 processors?

Answers

Answer 1
a. If the program is run with 100 processors and each processor is as fast as the single processor on which the serial program was run, it will take 1012/100 + 109(99) × 10-9 seconds for the program to run. This works out to be about 10.011 seconds.

b. If it takes 10-3 seconds to send a message, it will take 1012/100 + 109(99) × 10-3 seconds for the program to run. This works out to be about 9.991 seconds.

You are working with a database table that contains data about music. The table includes columns for track_id, track_name, composer, and milliseconds (duration of the music track). You are only interested in data about the classical musician Johann Sebastian Bach. You want to know the duration of each Bach track in seconds. You decide to divide milliseconds by 1000 to get the duration in seconds, and use the AS command to store the result in a new column called secs. Add a statement to your SQL query that calculates the duration in seconds for each track and stores it in a new column as secs. NOTE: The three dots (...) indicate where to add the statement.
SELECT
track_id,
track_name,
composer,

FROM
track
WHERE
composer = "Johann Sebastian Bach"

Answers

To calculate duration in seconds for each Bach track in a database table, the SQL query selects the track_id, track_name, composer, and divides the milliseconds column by 1000 to create a new column called "secs".

To calculate the duration in seconds for each track by dividing the milliseconds by 1000 and store it in a new column called "secs", the following statement should be added to the SQL query:

SELECT track_id, track_name, composer, milliseconds/1000 AS secs

FROM track

WHERE composer = "Johann Sebastian Bach"

This will return a result set with the track_id, track_name, composer, and duration in seconds as secs, only for tracks composed by Johann Sebastian Bach.

The given SQL query selects the track_id, track_name, and composer from the track table where the composer is "Johann Sebastian Bach". To get the duration in seconds for each track, the milliseconds column is divided by 1000 and the result is stored in a new column called "secs" using the AS command. The resulting query calculates the duration in seconds for each Bach track and includes it in the output.

3)Scissors or a knife

4Duct tape or hot glue

5)Measuring tape

6)!Pet food and water bowls

Steps:

1Choose two large plastic containers with lids. One will be used for food, and the other for water. Make sure they are deep enough to hold enough food and water for your pet.

2Using a measuring tape, mark the center of the bottom of each container.

3)Using scissors or a knife, cut a hole in the center of the bottom of each container. The hole should be large enough to fit the PVC pipe or cardboard tube, but small enough so that it can support the weight of the filled container.

4)Cut the PVC pipe or cardboard tube to the appropriate length so that it reaches the bottom of the container and sticks out above the top of the lid.

5)Insert the PVC pipe or cardboard tube through the hole in the bottom of the container and up through the hole in the lid.

6)Secure the PVC pipe or cardboard tube in place using duct tape or hot glue. Make sure it is firmly attached and stable.

7)Fill the food container with pet food and the water container with water.

8Place the containers on a flat surface and put the food and water bowls under the PVC pipe or cardboard tube.

9The food and water will flow down into the bowls by gravity as they are consumed by your pet.

10)That's it! You now have a simple gravity-fed pet feeder. Keep in mind that this design may not work for all types of pets or may need modifications for your specific pet's needs. Be sure to test the feeder and make sure your pet is able to use it safely and effectively.

The Java application to implement a dictionary is in the explanation part.

What is programming?

The process of carrying out a specific computation through the design and construction of an executable computer program is known as computer programming.

Here is an example implementation of a dictionary application in Java that uses a switch statement:

import java.util.HashMap;

import javax.swing.*;

public class DictionaryApp extends JFrame {

   private static final long serialVersionUID = 1L;

   private HashMap<String, String> dictionary;

   public DictionaryApp() {

       dictionary = new HashMap<String, String>();

       dictionary.put("algorithm", "a set of rules to be followed in calculations or other problem-solving operations");

       dictionary.put("data structure", "a particular way of organizing and storing data in a computer");

       dictionary.put("iteration", "the repetition of a process or set of instructions");

       dictionary.put("variable", "a value that can change or be assigned a new value");

       dictionary.put("function", "a self-contained block of code that performs a specific task");

       

       // Create GUI components

       JLabel wordLabel = new JLabel("Enter a word:");

       JTextField wordField = new JTextField(20);

       JTextArea definitionArea = new JTextArea(10, 20);

       JButton searchButton = new JButton("Search");

       // Create panel and add components

       JPanel panel = new JPanel();

       panel.add(wordLabel);

       panel.add(wordField);

       panel.add(searchButton);

       panel.add(new JScrollPane(definitionArea));

       // Add panel to frame

       this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

       this.add(panel);

       this.pack();

       this.setVisible(true);

       // Add event listener to search button

       searchButton.addActionListener((e) -> {

           String word = wordField.getText().toLowerCase();

           String definition = dictionary.get(word);

           switch (word) {

               case "":

                   definitionArea.setText("Please enter a word.");

                   break;

               case "exit":

                   System.exit(0);

                   break;

               default:

                   if (definition == null) {

                       definitionArea.setText("Word not found.");

                   } else {

                       definitionArea.setText(definition);

           }

       });

   }

   public static void main(String[] args) {

       new DictionaryApp();

   }

Summary
In this lab, you complete a prewritten C++ program that calculates an employee’s end-of-year bonus and prints the employee’s name, yearly salary, performance rating, and bonus. In this program, bonuses are calculated based on employees’ annual salary and their performance rating.

Instructions
Variables have been declared for you, and the input statements and output statements have been written. Read them over carefully before you proceed to the next step.
Design the logic, and write the rest of the program using a switch statement.
Execute the program by clicking the Run button at the bottom of the screen entering the following as input:
Employee’s name: Jeanne Hanson
Employee’s salary: 70000.00
Employee’s performance rating: 2
Confirm that your output matches the following:
Employee Name: Jeanne Hanson
Employee Salary: $70000
Employee Rating: 2
Employee Bonus: $10500



This is what I have:

cout << "Employee Bonus: $" << bonus << endl;


return 0;
}


what am I doing wrong?

Answers

Answer:

You need to write the code that calculates the bonus based on the employee's performance rating and salary. This calculation should be done inside the switch statement and the bonus variable should be updated with the correct value. You can use the numPerformanceRate and numSalary variables to determine the bonus, and the BONUS_1, BONUS_2, BONUS_3, and BONUS_4 constants to calculate the bonus.

Explanation:

switch (numPerformanceRate) {

 case RATING_1:

   bonus = numSalary * BONUS_1;

   break;

 case RATING_2:

   bonus = numSalary * BONUS_2;

   break;

 case RATING_3:

   bonus = numSalary * BONUS_3;

   break;

 case RATING_4:

   bonus = numSalary * BONUS_4;

Answers

To complete the Course class in NetBeans, we need to add data members for ID, Name, and Code, and implement setters and getters for each.

Additionally, we must provide a default constructor and an overloaded constructor that accepts three parameters to update the member variables.

Next, we need to create a driver class with a main method to instantiate the Course class and call its methods to change the ID, name, and code. In the main method, we can create a new instance of the Course class, set its data members using the setters, and retrieve their values using the getters.

Once the code is implemented, we can test and run it to verify that the class behaves as expected. This includes checking that the data members are correctly initialized, that the setters and getters work correctly, and that the overloaded constructor properly updates the member variables. By following these steps, we can ensure that our Course class is functional and ready for use in larger programs.

investigation on how to feed pets​

Answers

Feeding pets is an important aspect of pet care and requires careful consideration and planning to ensure that pets receive a balanced and nutritious diet. Here are some tips on how to feed pets:

Determine the appropriate diet: The type of diet that is appropriate for a pet will depend on several factors, including the pet's age, breed, activity level, and any health conditions. Pet owners should consult with a veterinarian to determine the appropriate diet for their pet.

Measure food portions: It is important to measure food portions to ensure that pets receive the correct amount of food. Overfeeding can lead to obesity and related health problems, while underfeeding can result in malnutrition. Pet owners should use measuring cups or a kitchen scale to ensure accurate portions.

Offer a balanced diet: A balanced diet for pets should include a combination of protein, carbohydrates, fats, vitamins, and minerals. Pet owners should ensure that their pet's food provides all the necessary nutrients for their health and well-being.

Offer fresh water: Pets should always have access to fresh water, which is essential for their health. Pet owners should clean and refill water bowls daily and make sure that the water is clean and free of contaminants.

Consider feeding frequency: The frequency of feeding will depend on the pet's age, breed, and activity level. Puppies and kittens typically need to eat more frequently than adult pets, while senior pets may need to eat less frequently. Pet owners should consult with a veterinarian to determine the appropriate feeding frequency for their pet.

Provide a safe and comfortable feeding area: Pets should have a designated feeding area that is safe, clean, and comfortable. The feeding area should be free of distractions and disruptions, and pets should be allowed to eat in peace.

Avoid table scraps: While it may be tempting to share human food with pets, this can lead to digestive problems and nutritional imbalances. Pet owners should avoid feeding their pets table scraps and stick to a balanced and nutritious diet that is appropriate for their pet.

In conclusion, feeding pets requires careful consideration and planning to ensure that pets receive a balanced and nutritious diet. By following these tips, pet owners can help their pets stay healthy and happy.

a) Find the speed up of the parallel program over the serial one.
b) The parallel program runs for a while in a serial mode and then in a parallel node. Find out the time the program spends in the serial mode of execution.

Answers

Answer:

a. Speed up = 3.125

b. Time spent in serial mode = 6800 seconds

Explanation:

a) The speed up of the parallel program can be found by dividing the time it takes to run on the serial system by the time it takes to run on the parallel system.

Speed up = Time to run on serial system / Time to run on parallel system

Speed up = 10000 seconds / 3200 seconds

Speed up = 3.125

b) To find the time the program spends in the serial mode of execution, we can subtract the time it takes to run on the parallel system from the total time it takes to run on the serial system.

Time spent in serial mode = Total time to run on serial system - Time to run on parallel system

Time spent in serial mode = 10000 seconds - 3200 seconds

Time spent in serial mode = 6800 seconds

Answers

The relation Order_Item_Detail requires normalization because it contains redundant data and violates the first normal form (1NF). For example, the Item_ID, Item_Name, Item_Unit_Price, and Item_Description repeat for multiple Order_ID's, which can lead to data inconsistency and anomalies when the data is updated or deleted.

How to convey the information

ii). The relation Order_Item_Detail is in the first normal form (1NF), as it meets the requirement of having a single value in each cell of the relation.

iii). The three update anomalies from the relation are:

Insert Anomaly: If we want to insert a new order for an item that does not already exist in the relation, we will have to insert the same item information multiple times.

Update Anomaly: If we want to update the item information, such as the price of an item, we would have to update the same information in multiple rows, leading to potential inconsistencies in the data.

Delete Anomaly: If we want to delete an order, we may end up deleting the item information as well, which may not be what we intended.

iv). To normalize the relation to 3NF, we need to follow the following steps:

Step 1: Create a new relation called Item_Detail with the following attributes:

Item_ID

Item_Name

Item_Unit_Price

Item_Description

Step 2: Create a new relation called Order_Detail with the following attributes:

Order_ID

Order_Date

Item_ID (Foreign Key referencing the Item_ID in Item_Detail)

Step 3: Remove the Item_Name, Item_Unit_Price, and Item_Description attributes from the Order_Item_Detail relation, and replace it with the foreign key, Item_ID, referencing the primary key in the Item_Detail relation.

The resulting relation Order_Detail will have the following structure:

Order_Detail

Order_ID Order_Date Item_ID

11 16-Nov-2022 101

11 16-Nov-2022 102

11 16-Nov-2022 103

18 29-Nov-2022 101

18 29-Nov-2022 108

The resulting relation Item_Detail will have the following structure:

Item_Detail

Item_ID Item_Name Item_Unit_Price Item_Description

101 Beef 1Kg 1,000 Beef Protein

102 Chicken 1Kg 1,250 Chicken Protein

103 Pork 1Kg 1,800 Pig Protein

108 Veal 1Kg 2,500 Deer Protein

v). After normalizing the relation to 3NF, we end up with two relations, Order_Detail and Item_Detail. The cardinality of the Order_Detail relation is 5 (number of rows), and the degree is 3 (number of columns).

______ refers to attacks where a mass email is sent to multiple computers, requesting personal information be sent to a specific location.

Answers

The term that refers to attacks where a mass email is sent to multiple computers, requesting personal information be sent to a specific location is "phishing."

Phishing is a type of cyberattack where an attacker sends a fraudulent email to many recipients in an attempt to trick them into providing sensitive information such as login credentials, credit card numbers, or other personal information. The email is designed to look like it comes from a legitimate source, such as a bank or an e-commerce site, and typically contains a link that takes the victimised by a phoney website that imitates the genuine one.

The victim is prompted to provide personal data once they arrive at the bogus website. The information is then collected by the attacker and can be used for various types of fraudulent activities, such as identity theft, financial fraud, and other forms of cybercrime.

Phishing attacks can be difficult to detect because the email and website may look very convincing. It is important to be cautious when clicking links in emails and to verify the authenticity of any website that asks for personal information.

Answers

The correct answer is (A), His hands and arms. Carpal tunnel syndrome is a condition caused by increased pressure on the median nerve in the wrist. Symptoms include pain, weakness, or tingling in the hands and arms.

Louis is experiencing symptoms of carpal tunnel syndrome, so he would be having pain, weakness, or tingling in his hands and arms.

Carpal tunnel syndrome is a condition caused by compression of the median nerve, which runs from the forearm into the hand. Symptoms typically include numbness, tingling, weakness, or pain in the thumb, index, middle, and ring fingers. These symptoms are due to the median nerve being compressed as it passes through the carpal tunnel, a narrow passageway in the wrist. The location of the symptoms in the hands and arms, specifically the fingers, is the hallmark of carpal tunnel syndrome.

A radio tower casts an 8-foot-long shadow at the same time that a vertical yardstick casts a shadow one half inch long. If the triangles formed by the objects and their shadows are similar, how tall is the radio tower?.

Answers

If the triangles formed by the objects and their shadows are similar, the height of the radio tower is 576 feet.

What is the height?

Height is a measure of vertical distance, either vertical extent.

Given that, the radio tower casts a shadow 8 feet long. At the same time that a vertical yardstick casts a shadow half an inch long

To find: the height of the radio tower

Let "x" be the height of the radio tower

Length of the shadow of the tower = 8 feet

Length of the shadow of stick = 1/2 inch

Length of the shadow of the stick = 0.0416 feet

Length of vertical yard stick = 3 feet (since 1 yard = 3 feet )

Height of the tower/length of the shadow power =  length of yardstick/ length of shadow stick.

x/8 = 3/ 0.0416

x = 8 x 72.11

x = 576

Therefore, the height of the radio tower is 576 feet approximately.

High-quality video and photographs may be captured with a digital camera, which is necessary for making a documentary.

While physical documents and photographs can be digitally preserved with scanners, videos are not routinely recorded using them.

A media player is a piece of software that can play audio and video files, although it's not frequently used to edit videos.

Although it is uncommon for a documentary to be produced with a projector, it is frequently utilized to show it to an audience.
