Answer:

Apache Hadoop.

Explanation:

Apache Hadoop is a open source program that uses map reduce programming process to allocate storage and processing of big data computation. It uses a network of computers, distributing and processing large data, for parallel computation.

The Apache Hadoop has two main parts, the Hadoop distributed file system and the MapReduce model. The Hadoop distributed file system divides large chunks of data into clusters and pass them to the MapReduce model, where they are separated to similar data types.

Explanation:

import java.util.Scanner;

public class Tester {

public static void main(String[] args) {

// create an object of scanner class

Scanner scanner = new Scanner(System.in);

//prompt user to enter first number

System.out.println("Enter first integer: ");

// read value from entered by user and keep it in num1

int num1 = scanner.nextInt();

//prompt user to enter second number

System.out.println("Enter second integer: ");

// read value from entered by user and keep it in num2

int num2 = scanner.nextInt();

//prompt user to enter third number

System.out.println("Enter third integer: ");

// read value from entered by user and keep it in num3

int num3 = scanner.nextInt();

//close scanner as we have done with user input

scanner.close();

//calculate sum

int sum = num1+num2+num3;

//calculate average

int average = sum/3;

//calculate product

int product = num1*num2*num3;

//find out largest number

int largest = 0;

if (num1>=num2){

largest = num1;

else

largest = num3;

}else {

if(num2>=num3)

}

// find out smallest number

int smallest = 0;

if(num1<=num3)

smallest = num1;

else

smallest = num3;

}else {

smallest = num2;

else

smallest = num3;

}

// print all the information

System.out.println("Sum of three numbers : "+sum);

System.out.println("Product of three numbers : "+product);

What traditional responsibilities are removed from an organization when moving to a cloud provider?

Black_prince [1.1K]

The traditional responsibilities removed from an organization when moving to a cloud provider includes;

Cloud provider providing system maintenance rather than IT personnel.

Responsibility for the provision of storage space will be borne by the cloud provider.

The provision of the required level of performance of shared IT hardware.

Provision of security for the organization's data will be partly shared.

Provision of capital for upgrade and expansion.

Reduced responsibility for the provision of space and hardware Universal access route to company sites.

Reasons:

The maintenance of the systems traditionally performed by the

organization is carried out by the cloud provider.

The storage space requirements for files and shared document are

provided by the cloud provider which results in increased collaboration.

Along with the changing landscape of technology, the cloud provider

ensures the optimum performance IT hardware that is shared by the

employees of the organization.

The Cloud provider ensures the security of the data stored on the cloud as

it is accessed from different devices.

The capital requirement for expansion is borne by the provider

With the use of cloud services, employees can work from home and other

remote locations.

Hey there! Hello!

In an instance of Microsoft Word 2016, you'll find that Merge Cells in the right-click option menu will do just what you're looking to. In Attachment 1, you'll find where the actual selection is, and in Attachment 2, you'll see what it did to the cells across the top, which were previously connected. I also added a different formatting to the table in the second attachment, the colors were not changed do to selecting Merge Cells.

Hope this helps you out! Feel free to ask me any additional questions if you have any. :-)
