Response:

Switch

Clarification:

A network switch is a piece of networking equipment, also referred to as a network bridging device, that links multiple devices within a network, allowing for data transmission between a source and a destination via packet switching.

To mitigate or minimize collisions in a network, modern wired networks utilize network switches where each device is attached to its individual port on the switch. This configuration turns the switch into a collision domain for half duplex connections, while in the case of full duplex links, the risk of collisions is entirely removed.

Answer:

I'm developing a function in C++. If you need it in a different programming language, just let me know.

void PrintFeetInchShort(int numFeet, int numInches){

   cout<<numFeet<<"\' "<<numInches<<"\"";

This function requires two integers, numFeet and numInches, as arguments. It employs cout to output the value of numFeet followed by a single quote, and subsequently the value of numInches, completed with double quotes. The character \ is utilized to introduce double quotes in the output. While using a backslash before a single quote isn't necessary, you could easily write cout<<numFeet<<"' " to display a single quote without it. However, the inclusion of backslash is essential for double quotes.

Explanation:

Here's the entire program to demonstrate how the function operates.

#include <iostream> // used for input and output operations

using namespace std;   // to enable usage of cout and cin without specific qualifying prefix

void PrintFeetInchShort(int numFeet, int numInches){

// function for printing in shorthand using ' and '

   cout<<numFeet<<"\' "<<numInches<<"\""; }

int main() { // beginning of main() body

  PrintFeetInchShort(5, 8);    }

// invokes PrintFeetInchShort() with arguments of 5 for //numFeet and 8 for numInches

To prompt the user for values of numFeet and numInches, do the following:

int main() {

   int feet,inches; // declares two integer type variables

   cout<<"Enter the value for feet:"; // asks user to provide the feet measurement

   cin>>feet; // inputs the feet value from user

   cout<<"Enter the value for inch:"; // asks user to provide the inch measurement

   cin>>inches;     // inputs the inch value from user

  PrintFeetInchShort(feet, inches);   } // invokes PrintFeetInchShort()

The screenshot of the program output has been attached.

Written in Python

G = 6.673 *pow(10,-11)

M = 5.98 *pow(10,24)

d = float(input("Enter distance: "))

g = (G * M)/(pow(d,2))

print("Calculated gravity acceleration: "+str(g))

Explanation:

The following line sets the gravitational constant

G = 6.673 *pow(10,-11)

This line establishes the mass of the Earth

M = 5.98 *pow(10,24)

This prompts the user to input the object's distance

d = float(input("Enter distance: "))

This calculates the gravity exerted on the object

g = (G * M)/(pow(d,2))

This line outputs the gravity acceleration without rounding

print("Calculated gravity acceleration: "+str(g))

int currentNumber,previousNumber = -1, countDuplicates = 0;

do {

cin >> currentNumber;

if ( previousNumber == -1) {

previousNumber = currentNumber;

}else {

if ( previousNumber == currentNumber )

countDuplicates++;

else

previousNumber = currentNumber;

}

} while(currentNumber > 0 );

cout << countDuplicates;

Question:

The function is_positive should yield True if the supplied number is positive; otherwise, it gives None. Can you fill in the blanks accordingly?

def is_positive(number):

       if  _____ :

           return _____

Answer:

def is_positive(number):

   if (number > 0):

       return True

  else:

       return "None"

---------------------------------------------------------------------------------

Code Test and Sample Output:

print(is_positive(6))

>> True

print(is_positive(-7))

>> None

----------------------------------------------------------------------------------

Explanation:

This segment of code is composed in Python.

To explain it further, let's break down the content of each line;

Line 1: Creates a function identified as is_positive which takes in a variable number.i.e

def is_positive(number):

Line 2: Evaluates if the given number is positive; a number qualifies as positive if it exceeds zero. i.e

if (number > 0):

Line 3: Produces a boolean result of True when the input number is positive. i.e

return True

Line 4: Initiates the else block to be executed in case the input number isn’t positive. i.e

else:

Line 5: Returns the string "None" when the number is not positive. i.e

return "None"

When combined, this results in;

===============================

def is_positive(number):

   if (number > 0):

       return True

   else:

       return "None"

================================

An instance test for the code provided an argument of 6 and -7, resulting in True and None respectively. i.e

print(is_positive(6))   = True

print(is_positive(-7))  = None
