Green Field county stadium is planning to conduct a cricket match between two teams A and B. A large crowd is expected in the st

PtichkaEL [24]

Answer:

RS422-A or RS-485

Explanation:

Mode Name: RS422-A

Well, this is the electrical interface. The microprocessor covers the logics to electrical signals, and these electrical signals are then transmitted over a long distance, which is less than 4000 feet through RS422-A. And this is a half-duplex mode with the multidrop receiver and one transmitter at a time, in master-slave format. A receiver is a slave and the transmitter is a master. And there can only be one transmitter at a time. Here, a PC collects the videos from all cameras, through a unified system, and this PC is connected to numerous receivers which are the Screens. Parallel transmission cannot be done over a single line, and it's noisy as well, and hence we stick to serial mode. and here half-duplex as one at a time need to deliver, and not both. Hence, RS422-A is the first mode. which is a half-duplex serial transmission mode.

Reason 1:

It's noiseless

Reason 2:

The number of receivers can be as high as 10.

As the second alternative option:

Mode Name: RS-485

This is even better and allows receivers as high in number as 32, and hence is better than RS-422A. The maximum distance allowed is around 4000 feet, and the rest is the same as RS-422A. it also supports half-duplex.

Reason 1: It's less noisy and even better than RS422-A

Reason 2: number of receivers, and as high as 32 are allowed.

Remember, however, Ethernet is a low distance network, though it also supports collision detection, and multiple access/ carrier detection or CSMA/CD. However, for this question requirement RS-422A and RS-485 network interface will work fine. In the case of ethernet, we have an Ethernet Interface card, which works as an Ethernet network interface. However, Ethernet is a short distance, and will not work here.

Create the Following Menu in a loop so the menu will continually show until the user chooses to exit.AddMultiplyExitAdd a value

ycow [4]

Answer:

I have added the code again with the mistakes are corrected please see the comments in code. You have mistake in while loop condition.

#include <iostream>

#include <iomanip>

#include <cmath>

using namespace std;

int options ();

int option1 ();

int option2 ();

int option3 ();

double addition (double num1, double num2);

double multiplication (double num1, double num2);

int main()

{

jump:

int option = 0;

cout << "1. Add" << endl;

cout << "2. Multiply" << endl;

cout << "3. Exit" << endl;

cout << "Enter option 1 for addition, option 2 for multiplication, or option 3 to exit" "Enter an option: ";

cin >> option;

switch (option)

{

case 1:option1;

int option1 ();

{

double num1 = 0;

double num2 = 0;

// void int key = 0;

cout << " Enter a number: ";

cin >> num1;

cout<< " Enter a second number: ";

cin >> num2;

double sum = addition(num1, num2);

cout << " Sum is: " << sum <<endl;

} break;

case 2: option2;

int option2 ();

{

double num1 = 0;

double num2 = 0;

cout << " Enter a number:";

cin >> num1;

cout << " Enter a second number: ";

cin >> num2;

double product = multiplication(num1, num2);

cout << " Product is: " << product << endl;

//system("cls");

}

break;

case 3: option3;

int option3();

{

return 0;

}

break;

default: cout << " Invalid number entered: ";

}

//do {main();}

//while (option < 3); //you have mistake in this loop please have a look

while (option<3)

{

goto jump;

}

double addition(double num1, double num2)

{

return num1 + num2;

}

double multiplication(double num1, double num2)

{

return num1*num2;

}

Explanation:

You can also do this by using goto statement in switch case and menu will be repeated until the user not select to exit and now it will work with the loop as well.

I hope it will help you!

Write the definition of a function typing_speed, that receives two parameters. The first is the number of words that a person ha

m_a_m_a [10]

Answer:

The function code and the formula for the above question is listed below:

Explanation:

Function:

float typing_speed(int Number_of_words, int Time_in_seconds)

{

float time= Time_in_seconds/60;

float speed= Number_of_words/time;

return speed;

}

Formula for this algorithm or program:

Number of words per minute= number of words/ Time(in minutes).

Function Explanation

The above function defined in the c-language code, which is used to return the typing speed for any user when he enters the number of words and the time in seconds.
The speed is calculated with the help of the above-defined formula.
The first statement of the code is used to change the time in a minute.
The second statement of the code is used to calculate the speed by the help of speed formula.
Then the third statement returns the value of the speed variable.

In this lab, you complete a Python program that calculates an employee's annual bonus. Input is an employee's first name, last n

HACTEHA [7]

Answer:

The program is as follows (See attachment)

Comments are used to explain some lines

Fname = input("Enter Employee First Name: ")

Lname = input("Enter Employee Last Name: ")

Salary = float(input("Enter Employee Salary: "))

Ratings = int(float(input("Enter Employee Ratings: ")))

#Initialize bonus rate to 0; This will be used if ratings is 4 or 4

bonusRate = 0.0

if Ratings == 1:

bonusRate =0.25 #If ratings is 1, bonus rate is 0.25

elif Ratings == 2:

bonusRate = 0.15 #If ratings is 2, bonus rate is 0.15

elif Ratings == 3:

bonusRate = 0.1 #If ratings is 3, bonus rate is 0.1

bonus = Salary * bonusRate

print(Lname+" "+Fname+"'s employee bonus is "+str(bonus))

#End of Program

Explanation:

The program saves the employee's first name and last name in variables Fname and Lname, respectively

The employee's salary is saved as float datatype in variable Salary

The employee's ratings is saved as int datatype in variable Ratings

For ratings greater than or equal to 4, the bonusRate is set to 0.0; this is done on line 6 of the program

Line 7 to 12 check if employee Ratings is 1, 2 or 3 and the respective bonusRate is used

Line 13 calculates the employee's bonus

Line 14 prints the employee's bonus

The program is ended on line 15
