Answer:

Full back up

It creates complete copy of the source of data. This feature made it to the best back up with good speed of recovery of the data and simplicity.However, because it is needed for backing up of a lot of data, it is time consuming process,Besides it also disturbs the routine application of the technologist infrastructure. In addition large capacity storage is needed for the storage of the large volume of back up with each new creation.

Incremental back up: back up work at high speed thus saves time, Little storage capacity is needed. This type of back up can be run as many time as wished.

However, the restoration of data takes time, due to the time spent for restoration of initial back up and the incremental.

Differential Back up has very fast back up operation, because it only requires two pieces of back up.This is however slower compare to the Incremental.

The selective back up enable selection of certain type of file or folders for back up.

it can only be used to back up folders only when important data are needed only.Thus the storage capacity is low.

CPD eliminates back up window and reduces the recovery point objective.However, it has issue of compatibility with the resources to back up.,it is also expensive because its solutions are disk based.

Cloud based is affordable and save cost,It is easier to access. it is efficient,it can be access remotely for convenience.

However, Internet sources and some bandwidth must be available for access., always depends on third party providers,There is also problems encountered when switching providers.

75,15,25,5,15 what's next

Fittoniya [83]

Answer:

Explanation:

The sequence seems to follow a 2-step pattern.

1)Divide the first number by 5 to get the second number.

2)Add 10 to the second number to get the third number.

75/5 = 15

15 + 10 = 25

25/5 = 5

5 + 10 = 15

---> 15/5 = [3] (Answer)

Iven an array temps of double s, containing temperature data, compute the average temperature. Store the average in a variable c

ale4655 [162]

Answer:

import java.util.Arrays;

import java.util.Scanner;

public class num1 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter length of the array:");

int len = in.nextInt();

double [] temps = new double[len];

double avgTem;

int k =0;

double total = 0;

for( k=0; k<temps.length; k++){

System.out.println("Enter values for the array");

temps[k]=in.nextDouble();

}

System.out.println("The Arrays contains the following values");

System.out.println(Arrays.toString(temps));

// Computing the average of the values

for(k=0; k<temps.length; k++){

total = total+temps[k];

}

avgTem = total/(temps.length);

System.out.println("The average Temperature is: "+avgTem);

}

Explanation:

Using Java programming language
Import the Scanner class to receive user input
Prompt User for the length of the Array, receive and store in a variable len;
Declare a new double array of size len double [] temps = new double[len];
Using a for loop, continually prompt user to enter values into the array
Display the values of the array using Java's Arrays.toString method
Use another for loop to add up all the elements in the arraay and store in the variable called total
Outside the second for loop calculate the average avgTem = total/(temps.length);
Display the average temp.
