Answer:

1. Easier collaboration.

2. Improved communications.

3. Increased productivity.

4. Reduced cost.

Explanation:

Computer network is a group of computers connected together using a common communication protocol for the purpose of transmitting data electronically and sharing resources such as internet, printers, scanner etc. The computer network is mainly divided into three, these include;

- Wide Area Network (WAN).

- Metropolitan Area Network (MAN).

- Local Area Network (LAN).

Also, a network is made up of nodes, which comprises of systems or devices that are connected to a network and are capable of sending, receiving or transferring data e.g switch, hub, computer, server, printer etc.

The benefits of the computer network are, it improves communication, convenient resources sharing, reduced operating costs, increase productivity, flexibility and efficiency for users.

Write a static method that implements a recursive formula for factorials. Place this method in a test program that allows the us

matrenka [14]

Answer:

Written in Java

import java.util.*;

public class Main {

public static int fact(int n) {

if (n == 1)

return n;

else

return n * fact(n - 1);

}

public static void main(String[] args) {

int num;

Scanner input = new Scanner(System.in);

char tryagain = 'y';

while(tryagain == 'y'){

System.out.print("Number: ");

num = input.nextInt();

System.out.println(num+"! = "+ fact(num));

System.out.print("Try another input? y/n : ");

tryagain = input.next().charAt(0);

}

Explanation:

The static method is defines here

public static int fact(int n) {

This checks if n is 1. If yes, it returns 1

if (n == 1)

return n;

If otherwise, it returns the factorial of n, recursively

else

return n * fact(n - 1);

}

The main method starts here. Where the user can continue executing different values of n. The program keep prompting user to try again for another number until user signals for stoppage

public static void main(String[] args) {

This declares num as integer

int num;

Scanner input = new Scanner(System.in);

This initializes tryagain as y

char tryagain = 'y';

This checks if user wants to check the factorial of a number

while(tryagain == 'y'){

This prompts user for input

System.out.print("Number: ");

This gets user input

num = input.nextInt();

This passes user input to the function and also prints the result

System.out.println(num+"! = "+ fact(num));

This prompts user to try again for another value

System.out.print("Try another input? y/n : ");

This gets user response

tryagain = input.next().charAt(0);

}

For what purpose do the hackers create the zombies army?

enyata [817]

Answer:

A. DDoS Attacks

Explanation:

A zombie, in computer terminology, is a hacker, computer worm, trojan horse, or virus compromised internet connected computer, which can be remotely directed to perform malicious tasks

E-mail spams and denial-of-service, DoS attacks are spread and launched by botnets of zombie computers

Botnets which are also known as "zombie army", are used by hackers mainly for spam and distributed-denial-of-service, DDoS, attacks

While a DoS attack involves one machine, while a DDoS attack consist of multiple computing devices and machines

A botherder is the originator of a botnet and common botnets include Mr Black. Pushdo, and cyclone

1. For the following program to be executed over the single accumulator

AlexFokin [52]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

#include <iostream> // it is preprocessor director that manipulate the input output in the program

using namespace std;// it is used to format input and output

int main() { // main function is started

int x = 5; // variable x is declared and initialized with value 5.

int y = 6; //variable y is declared and initialized with value 6.

int z = 34; //variable z is declared and initialized with value 34.

int total = (x+(x + y)*z+y); // variable total is declared and initialized with value of x,y,and z. and calculation performed on these value such as (5+(5+6)*34+6) that is equal to 385.

cout << total; // print the value of total variable that is 385

return 0;

what do we know about the contents of the arrays left and right with respect to what objects (integers) they contain in general

KIM [24]

A "divide and conquer" approach known as binary search necessitates sorting the starting array first. Because the technique divides the array into two equal halves, it is called a binary algorithm. A binary search will initially examine the middle item in the array and evaluate it in relation to the search terms.

<h3>What exactly is binary search?</h3>

Finding an element's location in a sorted array can be done using the searching method known as binary search.
With this method, an array's middle is always searched for the element. Only on a list of things that has been sorted can binary search be used. If the elements are not sorted already, we need to sort them first.
Binary search is used to find values in any sorted collection from any language library, including Java,.NET, C++ STL, etc.
A sorted array can be searched using the binary search algorithm by continually halving the search interval. Utilizing the knowledge that the array is sorted, binary search attempts to minimize the time complexity to O (Log n).
