The difference between a dot matrix printer and a line printer

Answer:

Definition and Properties. Code optimization is any method of code modification to improve code quality and efficiency. A program may be optimized so that it becomes a smaller size, consumes less memory, executes more rapidly, or performs fewer input/output operations.

Answer:

The program in Python is as follows:

nums = []

isum = 0

num = int(input("Num: "))

while num >= 0:

   isum+=num

   nums.append(num)

   num = int(input("Num: "))

print("Sum: ",isum)

print("Average: ",isum/len(nums))

print("Minimum: ",min(nums))

print("Maximum: ",max(nums))

Explanation:

My solution uses list to answer the question

This initializes an empty list, num

nums = []

This initializes the sum of the input to 0

isum = 0

This prompts the user for input

num = int(input("Num: "))

The loop is repeated until the user enters a negative number

while num >= 0:

This calculates the sum of the list

   isum+=num

This appends the input to the list

   nums.append(num)

This prompts the user for another input

   num = int(input("Num: "))

This prints the sum of the list

print("Sum: ",isum)

This prints the average of the list

print("Average: ",isum/len(nums))

This prints the minimum of the list

print("Minimum: ",min(nums))

This prints the maximum of the list

print("Maximum: ",max(nums))

File transfer protocol is the process whereby you transfer a file from your computer to the Internet.​

Answer:

A post is the process whereby you transfer a file from your computer to the Internet.​

Explanation:

Usually, when you post something from the internet, you would get a file from your device, and then post it by the way of your choice. For example, let's say I'm asking a question on Brainly, and I want to post a picture of a graph of a linear function. I would have to get the saved photo from my computer, upload it to the Brainly, and click "ASK YOUR QUESTION". So, a post is the process whereby you transfer a file from your computer to the Internet.​ Hope this helps!

Various companies crowdsource programs in order to have image libraries available to do certain tasks, one of those could be to see the landmark over time from different photos.

Answer: “Frame rate (expressed in frames per second or FPS) is the frequency (rate) at which consecutive images called frames appear on a display. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the frame frequency, and be expressed in hertz” this is what I searched up and maybe you can see what’s similar

Answer:

a. True

Explanation:

SimpleScalar refers to a computer architectural simulating software application or program which was designed and developed by Todd Austin at the University of Wisconsin, Madison, United States of America. It is an open source simulator written with "C" programming language and it's used typically for modelling virtual computer systems having a central processing unit (CPU), memory system parameters (hierarchy), and cache.

The main purpose of SimpleScalar is to avail developers or manufacturers the ability to compare two computers based on their capacities (specifications) without physically building the two computers i.e using a simulation to show or illustrate that computer B is better than computer A, without necessarily having to physically build either of the two computers.

Hence, it is an architectural simulator which makes it possible to study how different central processing units (CPUs), memory hierarchy or system parameters and cache affect the performance and energy efficiency of a computer system.

The shape is unknown

You must define a shape first before calculating area

The area is 0.0

You must define a shape first before calculating perimeter

The perimeter is 0.0

Enter the radius of the circle

>> 12

The area is 452.448

Enter the radius of the circle

>> 12

The perimeter is 452.448

The properties of the shape are

Shape : circle

Perimeter : 75.408

Area : 452.448

The difference is 377.03999999999996

Explanation:

The following code is written in Java. It creates the three classes mentioned and a Tester class that contains the main method. The Computer class contains the memory variable since both laptops and Desktops need memory. The screen size variable is placed separately in the Laptop and Desktop class since desktops may or may not have a monitor so this variable cannot be placed in the Computer class. The batteryLife variable is only in the Laptop class because Desktops do not have batteries. Finally, the monitor variable is only placed in the Desktop class since Laptop's come with built-in monitors. The tester class seen in the picture below tests the creation of both of these objects and it executes without any error.

class Computer {

   int memory;

   public int getMemory() {

       return memory;

   }

   public void setMemory(int memory) {

       this.memory = memory;

   }

}

class Laptop extends Computer {

   int screenSize;

   double batteryLife;

   public int getScreenSize() {

       return screenSize;

   }

   public void setScreenSize(int screenSize) {

       this.screenSize = screenSize;

   }

   public double getBatteryLife() {

       return batteryLife;

   }

   public void setBatteryLife(double batteryLife) {

       this.batteryLife = batteryLife;

   }

}

class Desktop extends Computer {

   boolean monitor;

   int screenSize;

   public boolean isMonitor() {

       return monitor;

   }

   public void setMonitor(boolean monitor) {

       this.monitor = monitor;

   }

   public int getScreenSize() {

       return screenSize;

   }

   public void setScreenSize(int screenSize) {

       this.screenSize = screenSize;

   }

}

class Tester {

   public static void main(String[] args) {

       Laptop computer1 = new Laptop();

       Desktop computer2 = new Desktop();

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

double *sum_n_avg(double n1, double n2, double n3);

int main () {

   double n1, n2, n3;

   cout<<"Enter 3 inputs: ";

   cin>>n1>>n2>>n3;

   double *p;

   p = sum_n_avg(n1,n2,n3);

   cout<<"Sum: "<<*(p + 0) << endl;

   cout<<"Average: "<<*(p + 1) << endl;

  return 0;

}

double *sum_n_avg(double n1, double n2, double n3) {

  static double arr[2];

  arr[0] = n1 + n2 + n3;

  arr[1] = arr[0]/3;

  return arr;

}

Explanation:

This defines the function prototype

double *sum_n_avg(double n1, double n2, double n3);

The main begins here

int main () {

This declares variables for input

   double n1, n2, n3;

This prompts the user for 3 inputs

   cout<<"Enter 3 inputs: ";

This gets user inputs

   cin>>n1>>n2>>n3;

This declares a pointer to get the returned values from the function

   double *p;

This passes n1, n2 and n3 to the function and gets the sum and average, in return.

   p = sum_n_avg(n1,n2,n3);

Print sum and average

   cout<<"Sum: "<<*(p + 0) << endl;

   cout<<"Average: "<<*(p + 1) << endl;

  return 0;

}

The function begins here

double *sum_n_avg(double n1, double n2, double n3) {

Declare a static array

  static double arr[2];

Calculate sum

  arr[0] = n1 + n2 + n3;

Calculate average

  arr[1] = arr[0]/3;

Return the array to main

  return arr;

}

Explanation:

The ith column of an identity matrix is the unit vector ei (the vector whose ith entry is 1 and 0 elsewhere) It follows that the determinant of the identity matrix is 1, and the trace is n. When the identity matrix is the product of two square matrices, the two matrices are said to be the inverse of each other.

Answer:

The program in C++ is as follows:

#include<iostream>

using namespace std;

void displayData(int height, int length, double Area){

   printf("Height: %d \n", height);

   printf("Length: %d \n", length);

printf("Area: %.2f \n", Area);

}

double trigArea(int height, int length){

double area = 0.5 * height * length;

   displayData(height,length,area);

   return area;

}

void getData(){

   int h,l;

   cin>>h>>l;

   trigArea(h,l);

}

int main(){

   getData();

   return 0;

Answer:

Follows are code to the given question:

def countdown_trigger(begin):#defining a method countdown_trigger that accepts a parameter

   i = begin#defining variable that holds parameter value

   while i >= 0:#defining while loop that check i value greater than equal to0

       print(i)#print i value

       i -= 2  # decreasing i value by 2  

print(countdown_trigger(2))#calling method

Output:

2

0

None

Explanation:

In this code, a method "countdown_trigger" is declared, that accepts "begin" variable value in its parameters, and inside the method "i" declared, that holds parameters values.

By using a while loop, that checks "i" value which is greater than equal to 0, and prints "value" by decreasing a value by 2.
