Answer:

SCAN disk scheduling is the algorithm in which a certain arm of disk rotates in particular direction and serves the requests that arrive from that path. It scans the cylinder's disk in both back and forth direction.

If the arm reaches the bottom of the disk , it automatically stars working in the opposite direction and serves the request in the reverse direction path.As this functioning is similar to the elevator movement ,it is also known as elevator algorithm.

2. Next user can login into cloud accounts nothing but hot mail accounts

3. Login to windows domain controller where end user should connect to LAN.

Purpose of installation of Windows domain controller with Active Directory is to keep trace and keep log history activities.

Due to windows domain controller with Active Directory end user desktop or laptop has control on software access also.

Write a program that will prompt the user to enter an integer. The program should square the number and then print the squared n

Kay [80]

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// function to compute sum and product

void square(int input)

{

// variable to store the square of number

long long squ_num;

calculate the square of number

squ_num=pow(input,2);

// print the output

cout<<"square of "<< input<<" is: "<<squ_num<<endl;

}

// driver function

int main()

{

int n;

// read the number until user enter 0

do{

cout<<"enter a number!! (0 to stop):";

// read the input from user

cin>>n;

// call the function to calculate square of input number

square(n);

}while(n!=0);

return 0;

}

Explanation:

Declare a variable "n" to read the input number from user.Call the function square() with parameter "n".In this function, it will calculate the square of the input number and print it.This will repeat until user enter 0 as input.Program will ends when user give 0 as input.

Output:

enter a number!! (0 to stop):5

square of 5 is: 25

enter a number!! (0 to stop):7

square of 7 is: 49

enter a number!! (0 to stop):11

square of 11 is: 121

enter a number!! (0 to stop):0
