Answer:

Ans 1.To connect to the Internet and other computers on a network, a computer must have a NIC (network interface card) installed. A network cable plugged into the NIC on one end and plugged into a cable modem, DSL modem, router, or switch can allow a computer to access the Internet and connect to other computers.

Ans 2.Data travels across the internet in packets. Each packet can carry a maximum of 1,500 bytes. ... When you send an e-mail to someone, the message breaks up into packets that travel across the network. Different packets from the same message don't have to follow the same path.

Ans 3.protocol is a set of rules that governs the communications between computers on a network. A network protocol defines rules and conventions for communication between network devices.

Write a function with two parameters, prefix (a string, using the string class from ) and levels (an unsigned integer). The func

Allisa [31]

Answer:

Here is the program:

#include <iostream> //to use input output functions

#include <string> // to use functions to manipulate strings

using namespace std; //to identify objects cin cout

void function(string prefix, unsigned int levels){ // function that takes two parameters, a string, using the string class and levels an unsigned integer

if (levels == 0) { //if number of levels is equal to 0

cout << prefix << endl; //displays the value of prefix

return; }

for (int i = 1; i <=9 ; i++){ //iterates 1 through 9 times

string sections = (levels == 1 ? "" : "."); //if the number of levels is equal to 1 then empty space in sections variable otherwise stores a dot

string output = prefix + std::to_string(i) + sections; // displays the string prefix followed by the section numbers. Here to_string is used to convert integer to string

function(output, levels - 1); } } //calls function by passing the resultant string and levels-1 recursively to print the string prefix followed by section numbers

int main() { // start of main function

int level = 2; //determines the number of levels

function("BOX", level); } //calls function by passing the string prefix and level value

Explanation:

The program has a function named function() that takes two parameters, prefix (a string, using the string class from ) and levels (an unsigned integer). The function prints the string prefix followed by "section numbers" of the form 1.1., 1.2., 1.3., and so on. The levels argument determines how many levels the section numbers have. If the value of levels is 0 means there is 0 level then the value of prefix is printed. The for loop iterates '1' through '9' times for number of digits in each level. If the number of levels is 1 then space is printed otherwise a dot is printed. The function() calls itself recursively to print the prefix string followed by section numbers.

Let us suppose that prefix = "BOX" and level = 1

If level = 1 then the loop for (int i = 1; i <=9 ; i++) works as follows:

At first iteration:

i = 1

i <=9 is true because value of i is 1

string sections = (levels == 1 ? "" : "."); this statement checks if the levels is equal to 1. It is true so empty space is stored in sections variable so,

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement has prefix i.e BOX plus value of i which is 1 and this int value is converted to string by to_string() method plus sections has an empty space. So this statement becomes

string output = BOX + 1

So this concatenates BOX with 1 hence output becomes:

output = BOX1

At second iteration:

i = 2

i <=9 is true because value of i is 2

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement becomes

string output = BOX + 2

So this concatenates BOX with 1 hence output becomes:

output = BOX2

At third iteration:

i = 3

i <=9 is true because value of i is 3

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement becomes

string output = BOX + 3

So this concatenates BOX with 1 hence output becomes:

output = BOX3

Now at each iteration the prefix string BOX is concatenated and printed along with the value of i. So at last iteration:

At last iteration:

i = 9

i ==9 is true because value of i is 9

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement becomes

string output = BOX + 9

So this concatenates BOX with 1 hence output becomes:

output = BOX9

After this the loop breaks at i = 10 because the condition i<=9 becomes false. So the output of the entire program is:

BOX1 BOX2 BOX3 BOX4 BOX5 BOX6 BOX7 BOX8 BOX9

The program along with the output is attached.

What is administrator access? Multiple Choice refers to how quickly a system can transform to support environmental changes perf

IrinaVladis [17]

Answer:

Administrator access is:

refers to the varying levels that define what a user can access, view, or perform when operating a system refers to the time frames when the system is operational

Explanation:

The reasons behind this answer are that in the first place the administrator role is the maximum role an account can have in the operating system. Controlling the different levels of access the rest of the accounts can have on the system. It then is a hierarchical role, not the changes someone can execute in a certain environment, these are called rules.

) For a course with n students, an n X 3 array, int[][] arr, holds scores on 3 exams. Each row holds the exam scores for one stu

anzhelika [568]

Answer:

Following are the code to this question:

import java.util.*;//import package

public class Main //defining a class

{

public static void main(String[] ax)//defining main method

{

int student[][] = {{50,60,65},{75,85,90}}; //defining double array student

int Row=0,Col=0;//defining integer variable

double x;//defining double variable

for (int a = 0; a <student.length; a++)//use for loop to holding row value

{

for (int b = 0; b<student[a].length; b++)//use for loop to holding column value

{

Row += student[a][b];//add row value

Col += student[0][b];//add column value

}

System.out.println(x=Row/2);//dividing value and calculating average value

}

Output:

212.0

Explanation:

In the above code, a 2D array student is declared, that holds some value in the next step, two integer variable "Row and Col", is declared, which it uses the for loop to add value in "Row and Col", and in the next step, a double variable x is declared, that add value and calculates its average value and store its value in x variable and print its value.

What is the deck of a suspension bridge called

dedylja [7]

Answer:

The main forces in a suspension bridge are tension in the cables and compression in the towers. The deck, which is usually a truss or a box girder, is connected to the suspension cables by vertical suspender cables or rods, called hangers, which are also in tension. I think this is the answer
