Answer:

Circuit breakers and fuses both have the same purpose, but a fuse will melt when stopping electricity where as circuit breakers can just be reset. You need both devices in order to stop a overload of power that could fry your electronics or worse, start fires.

Answer:

$\huge\sf \pink{circuit \: Breaker:}\$

It's A device used to protect an electrical circuit from damage caused by overcurrent/overload or short circuit.
Function: To interrupt current flow after protective relays detect a fault.
Why do we need them : It disrupts the flow of a current if there's a short circuit or overload. In doing so, it can prevent damage to an electrical circuit and possibly appliances, electronics, and our home.

$\huge\sf \pink{Fuse:}\$

It's A device that protects circuits and appliances by stopping the flow of unduly high electric current.
Function :The basic function of fuse is to prevent fire .It breaks electrical circuit if there occurs a fault in electrical appliances that causes too much current flow.
why do we need them : Without a fuse, there are many possibilities for electrical fires or extreme damage to a circuit.

Create a program that allows the user to pick and enter a low and a high number. Your program should generate 10 random numbers

Natalka [10]

Answer:

import java.util.Scanner;

import java.util.Arrays;

import java.util.Random;

public class Main {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.print("Enter low: ");

int low = scan.nextInt();

System.out.print("Enter high: ");

int high = scan.nextInt();

scan.close();

int rndnumbers[] = new int[10];

Random r = new Random();

for(int i=0; i<rndnumbers.length; i++) {

rndnumbers[i] = r.nextInt(high-low+1) + low;

}

for(int i=0; i<rndnumbers.length; i++) {

System.out.printf("%d: %d\n", i, rndnumbers[i]);

Which is a connectionless protocol in the transport layer? What are the small chunks of data called?

xeze [42]

Answer:

User Datagram Protocol (UDP) , transport-layer segment.

Explanation:

The User Datagram Protocol is popularly known as UDP. It is defined as the communication protocol which is used across the internet for any time sensitive transmission like the DNS lookup or the video playback.

The UDP provides a unreliable and connectionless service to a invoking application.

The transport layers on sending side converts the application $\text{layer }$ messages which it $\text{receives}$ from the $\text{sending application process}$ into a transport layer segment called as the transport layer segments. This is achieved by breaking down the application messages into a smaller chunks and then adding the transport layer header into each chunk so as to create a transport layer segment.
