Answer: Wired Equivalent Privacy (WEP) has the major disadvantage of having a shared key of encryption for all the clients.

Explanation: Wired Equivalent Privacy (WEP) is the protocol for providing the security to the WiFi and other network of 802.11 standard. It secures the data in by the method of encryption.Though it has a drawback that it encrypts the the data in shared key form and it has most chances of not able to change the key which is not a convenient feature for the clients.

Answer:

Wired equivalent privacy standard has the significant disadvantages as, it is uses the static encryption keys. Wired equivalent privacy are the security and the privacy protocol which are used for designing the wireless local area network. And the static encryption key are used to set up the router for encrypting the packet in the device. The main disadvantage is that it enables the MAC address and it is easily detectable by the hackers.

A microcomputer is a small device composed of a central CPU with a microprocessor. Microcomputers are also called personal computers (PCs) and they are ultimately easier to transport.

<h3>What is a microcomputer?</h3>

A microcomputer refers to a personal computer, which is similar to an IBM PC device machine.

The term microcomputer was used in the 1970s, nowadays they are called personal computers, and PCs are being increasingly better both in usage and transportability.

The average personal computer has a weight of 20-30 pounds, in the future, it is believed that there will be no need for a personal computer (all data will be in the cloud).

Which tool encrypts entire drives, rendering them unusable unless one possesses the correct key to unlock the drive?
xxMikexx [17]

Answer:

Whole disk encryption.

Explanation:

Whole disk encryption, also known as, the full disk encryption is a tool that encrypts the entire drive. The whole disk encryption protects the whole hard drive from unwanted visitor to enter into your system.

<u>This tool protects your entire data, softwares, files, etc stored in the hard drive. Whole disk encryption cedes the entire hard drive unusuable untill correct key is entered to unlock the drive.</u>

Thus the correct answer is 'whole disk encryption.

Use JavaWrite a program that will simulate a change machine found at cash registers. Input the amount due and amount paid from t
Ksju [112]

Answer:

Here is the JAVA program:

import java.util.Scanner;  //to accept input from user

public class Main { // class name

 public static void main(String [] args) {  // start of main method

   Scanner input = new Scanner(System.in);  // creates Scanner class object to take input from user

   System.out.println("Please Enter the Cost of the Item: ");  // prompts user to enter the cost of item

   double itemCost = input.nextDouble();  //scans and reads the input value of item cost

   System.out.println("Please Enter the Amount Paid: ");  // prompts user to enter the amount paid

   double amount = input.nextDouble();  //scans and reads the value of amount from user

   int change = (int)(amount * 100 - itemCost * 100);  //compute the remaining amount i.e. change

   System.out.println("Change Owed: " + change / 100.0);  // displays the owed change

   int quarters = change / 25;  // computes the value for quarters

   change = change % 25;  // compute the quarters remaining

   int dimes = change / 10;  //  computes dimes

   change = change % 10;  //  computes dimes remaining

   int nickels = change / 5;  // computes nickels

   change = change % 5;  // compute nickels remaining

   int pennies = change;  // computes pennies

   System.out.println("Quarters: " + quarters);  // displays computed value of quarters

   System.out.println("Dimes: " + dimes);  // displays value of dimes

   System.out.println("Nickels: " + nickels);  // displays value of nickels

   System.out.println("Pennies: " + pennies);   }} //displays value of pennies

Explanation:

I will explain the program with an examples.

Suppose the user enters 4.57 as cost of the item and 5.00 as amount paid. Then the program works as follows:

Change is computed as

change = (int)(amount * 100 - itemCost * 100);

This becomes;

change = (int)(5.00 * 100 - 4.57 * 100)

            = 500 - 457

change = 43

Now the change owed is computed as:

change / 100.0 = 43/100.0 = 0.43

Hence change owed = 0.43

Next quarters are computed as:

quarters = change / 25;

This becomes:

quarters = 43/25

quarters = 1

Now the remaining is computed as:

   change = change % 25;

This becomes:

   change = 43 % 25;

  change = 18

Next the dimes are computed from remaining value of change as:

dimes = change / 10;

dimes = 18 / 10

dimes = 1

Now the remaining is computed as:

   change = change % 10;

This becomes:

   change = 18 % 10

  change = 8

Next the nickels are computed from remaining value of change as:

nickels = change / 5;

nickels = 8 / 5

nickels = 1

Now the remaining is computed as:

   change = change % 5;

This becomes:

   change = 8 % 5

  change = 3

At last the pennies are computed as:

pennies = change;

pennies = 3

So the output of the entire program is:

Change Owed: 0.43                                                                                                                Quarters: 1                                                                                                                      Dimes: 1                                                                                                                         Nickels: 1                                                                                                                       Pennies: 3  

The screenshot of the output is attached.
