Answer:

DiffServ (Differentiated Service)

Explanation:

DiffServ (Differentiated Service) field is used to prioritize traffic in IPv4 packet.

DiffServ is used as QoS (quality of service) on networks at Layer 3, replacing former IPv4 TOS field to effectively deal with the web traffic and prioritization issues starting from 1998.

How will you apply the different wiring devices according to its main purposes and functions?

Gekata [30.6K]

Answer:Wiring devices are current-carrying electrical or electronic products that serve primarily as a connection or control point for electrical circuits within a range of 0–400 amperes, 0–600 volts (AC and DC), and AC/DC (660 watts, 1,000 volts AC fluorescent) as well as certain non-current-carrying wiring devices and supplies.

Wiring devices include:

Convenience plugs and power outlets (plugs and receptacles)

Connector bodies and flanged outlets

Cover plates

General-use switches and dimmers

Lampholders (incandescent, fluorescent, cold cathode, neon, quartz lamps, and others)

Lighting control devices

Motion sensing and timer switches

Receptacles

Switch, outlet, FM/TV, blank, and telephone plates

Undercarpet premise wiring systems

Products include receptacle-type arc-fault circuit interrupters (AFCIs), protection devices that can detect an unintended electrical arc and disconnect the power before the arc starts a fire. AFCI technology in residential and commercial buildings is an important electrical safety device.

7. Test Average and Grade Write a program that asks the user to enter five test scores. The program should display a letter grad

Alenkasestr [34]

Answer:

The code solution is written in Java.

import java.util.Scanner;
public class TestScore {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter first score: ");
double firstScore = input.nextDouble();
System.out.println("Grade: " + determineGrade(firstScore));
System.out.print("Please enter second score: ");
double secondScore = input.nextDouble();
System.out.println("Grade: " + determineGrade(secondScore));
System.out.print("Please enter third score: ");
double thirdScore = input.nextDouble();
System.out.println("Grade: " + determineGrade(thirdScore));
System.out.print("Please enter fourth score: ");
double fourthScore = input.nextDouble();
System.out.println("Grade: " + determineGrade(fourthScore));
System.out.print("Please enter fifth score: ");
double fifthScore = input.nextDouble();
System.out.println("Grade: " + determineGrade(fifthScore));
System.out.println("Average score: " + calcAverage(firstScore, secondScore, thirdScore, fourthScore, fifthScore));
}
public static double calcAverage(double score1, double score2, double score3, double score4, double score5){
double average = (score1 + score2 + score3 + score4 + score5) / 5;
return average;
}
public static String determineGrade(double score){
if(score >= 90){
return "A";
}
else if(score >= 80 ){
return "B";
}
else if(score >=70){
return "C";
}
else if(score >=60){
return "D";
}
else{
return "F";
}
}
}

Explanation:

Firstly, create the method, calcAverage(), that takes five test scores. Within the method, calculate the average and return it as output. (Line 33 - 36)

Next, create another method, determineGrade(), which takes only one score and return the grade based on the range of the score. (Line 38 -54)

Once the two required methods are created, we are ready to prompt use for input five test scores using Java Scanner class. To use get user input, create a Scanner object (Line 7). Next, use getDouble() method to get an input score and assign it to variables firstScore, secondScore, thirdScore, fourthScore & fifthScore, respectively. Once a score input by user, call determineGrade() method by passing the input score as argument and immediately print out the return grade. (Line 9 - 27)

At last, call calcAverage() method by passing the first test score variables as argument and print out the returned average value. (Line 29).

int i2 = Integer.parseInt(s2);

int i3 = Integer.parseInt(s3);

int sum = i1 + i2 + i3;

return sum;

}

Explanation:

- Create a method called sumStrings that takes three strings

- Convert each string to integer using Integer.parseInt() method
