A company moves a popular website to a new web host. Which of the following will change as a result?

Write a method called makeStars. The method receives an int parameter that is guaranteed not to be negative. The method returns

serious [3.7K]

Answer:

// import the Scanner class

// to allow the program receive user input

import java.util.Scanner;

// The class Solution is defined

public class Solution{

// main method to begin program execution

public static void main(String[] args) {

// scanner object scan is declared

Scanner scan = new Scanner(System.in);

// Prompt the user to enter a number

System.out.println("Enter the number of stars you want: ");

// user input is assigned to numOfStar

int numOfStar = scan.nextInt();

// call the makeStars method

makeStars(numOfStar);

}

// makeStars method print stars using recursion

// the method call itself till starNum == 0

public static void makeStars(int starNum){

if (starNum != 0){

System.out.print("*");

makeStars(starNum -1);

}

Explanation:

The code is well comment and solve the problem using recursion.

g Suppose the information content of a packet is the bit pattern 1110 0110 1001 1101 and an even parity scheme is being used. Wh

erma4kov [3.2K]

Answer: see description

Explanation:

first we accommodate the bit pattern in a matrix of 4x4 which is the minimum length checksum field, now with even parity two-dimensional scheme we need to complete this matrix by adding one row and one column by adding at the end of each row a 1 or a 0 to complete pairs of 1's:

we have

$\left[\begin{array}{cccc}1&1&1&0\\0&1&1&0\\1&0&0&1\\1&1&0&1\end{array}\right]$

so we complete with this, adding a row at the end which matches a pair number of 1's

$\left[\begin{array}{ccccc}1&1&1&0&1\\0&1&1&0&0\\1&0&0&1&0\\1&1&0&1&1\\1&1&0&0&0\end{array}\right]$

kakasveta [241]

Answer:

You can perform the following two steps

Explanation:

Have the user press the appropriate function key combination to enable the wireless radio and then attempt to connect to the wireless network (since by mistake he could have disabled it).
Ask the user to turn on the laptop’s airplane mode and attempt to reconnect to the wireless network (this mode basically what it does is disable adapters and activate it will connect the Wi-Fi network).

You are an ISP. For the Address Block 195.200.0.0/16 a. If you have 320 Customers that need 128 addresses/customer - will there

12345 [234]

Answer:

a. The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 195.200.0.0/22

Explanation:

195.200.0.0/16

The number of bits to give 512 is 9

2^9=512

2^8=256 which is not up to our expected 320 customers that requires a network ip

Note we have to use a bit number that is equal or higher than our required number of networks.

The number of host per each subnet of the network (195.200.0.0/25) is (2^7)-2= 128-2=126

The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 64 customers requires 6 bits to be taken from the host bit to the network bit

i.e 2^6 = 64

195.200.0.0/22

The number of host per each subnet of the network (195.200.0.0/22) is (2^10)-2=1024 - 2 = 1022 hosts per subnet

This network meet the requirement " 64 customers want 128 addresses/customer "
