Answer:D)Power Options

Explanation: Power options are the options present on the Control Panel of the Windows system.They are used for the adjustment of the power settings and power plane.The functions that can be done using the power options are controlling the accounts of user, elimination of hardware and software, addition of the hardware and software etc.

The user can control the sleep mode of the laptop through power options.Other options are incorrect because display setting is for change in the display of the background of desktop, icons etc,action center gives the notification and system is the operating unit .Thus the correct option is option(D).

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integer
Xelga [282]

Answer:

import java.util.Scanner;

public class ListOfIntegers {

public static void main(String[] args) {

 // Create an object of the Scanner class to allow for user input

 Scanner input = new Scanner(System.in);

 // Prompt the user for the number of integers they want to enter

 System.out.print("Enter the number of integers : ");

 // Get and store the number of integers entered by user

 int n = input.nextInt();

 System.out.println();

 // Create an array to hold the integers

 // The array has the same length as the number of integers

 int[] numbers = new int[n];

 // Create a loop that asks the user to enter all integers

 // At each cycle of the loop, save the entered integer into the array

 for (int i = 0; i < n; i++) {

  System.out.print("Enter number " + (i + 1) + " : ");

  numbers[i] = input.nextInt();

  System.out.println();

 }

 // Prompt the user for the lower bound

 System.out.print("Enter the lower bound : ");

 // Get and store the lower bound in a variable

 int lowerbound = input.nextInt();

 System.out.println();

 // Prompt the user for the upper bound

 System.out.print("Enter the upper bound : ");

 // Get and store the upper bound in a variable

 int upperbound = input.nextInt();

 System.out.println();

 System.out.println("OUTPUT :: ");

 // Create a loop to cycle through the array of numbers.

 // At each cycle, check if the array element is within range.

 // If it is within range, print it to the console

 for (int j = 0; j < numbers.length; j++) {

  if (numbers[j] >= lowerbound && numbers[j] <= upperbound) {

   System.out.print(numbers[j] + " ");

  }

 }

}

}

If a file is opened for reading and the file does not exist,what action is taken?
worty [1.4K]

Answer:

C)An error message is issued.

Explanation:

If we try to open a file for reading when that file does not exist, we will get an error message.

For example, in Java we will encounter a FileNotFoundException as in the code below:

       try {

           FileInputStream fis = new FileInputStream("myFile.txt");

           DataInputStream dis = new DataInputStream(fis);

           BufferedReader br = new BufferedReader(new InputStreamReader(dis));

           String str = null;

           while ((str = br.readLine()) != null) {

               System.err.println(str);

           }

       } catch (FileNotFoundException e) {

           e.printStackTrace();

       }

If the file myFile.txt does not exist we can expect to see an exception stack trace corresponding to FileNotFoundException.

In the context of firewall as a nonbiometric security measure, a _____ is software that acts as an intermediary between two syst
irga5000 [103]

Answer:

Proxy Server                        

Explanation:

  • Proxy server is a server that acts as a mediator between two systems.
  • One system can be your computer and the other can be the server to which you are asking a service, such as requesting a web page.
  • Lets suppose you request a web page from a server and you type a URL of a website to access a web page.
  • This request goes to proxy server which sends this request on your behalf to the target server in order to retrieve that web page.
  • Proxy server makes this request to the target server on the internet by using one of its IP addresses.
  • When the proxy server gets that web page, it will forward that web page to your requesting computer.
  • If you request a specific service such as a website frequently the proxy server saves that website on its cache.
  • So if you request that website again, proxy server will forward it to you from its cache rather than requesting it again from the target server on your behalf resulting in quick response to the user's request.
  • Proxy servers provide users with privacy to access the websites, and they can surf the internet anonymously .
