Describe and list advantages and disadvantages of each of the following backup types:
crimeas [40]

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.

Urgent. I will mark you brainliest. explain why cyber warfare is a real threat.​
stellarik [79]

Answer: Cyber warfare is a real threat since being able to hack another computer especially a countries computer with lots of info in their weaknesses can lead to their downfall. Since they can even possibly if their skilled enough hack their entire data base system and leak it to the public and that wouldn't be good for them not in a single possible way. That's the reason it's dangerous not only that but also because they can access their servers; which can let them access anything online from the whole country including banking information military info which can let them know which area there gonna go to next equipment there gonna bring and where they're gonna launch missiles, bombs, even nukes if they decide to launch one. And being able to hijack the computer that launches the nukes can make the hacker launch the nuke to a different place or launch the nuke on the country trying to launch the nuke.

Answer:

Check the explanation

Explanation:

/*Given the following program:

public class MysteryNumbers {

   public static void main(String[] args) {

       String one = "two";

       String two = "three";

       String three = "1";

       int number = 20;

​

       sentence(one, two, 3);

       sentence(two, three, 14);

       sentence(three, three, number + 1);

       sentence(three, two, 1);

       sentence("eight", three, number / 2);

   }

​

   public static void sentence(String three, String one, int number) {

       System.out.println(one + " times " + three + " = " + (number * 2));

   }

}*/

Write the output of each of the following calls.

sentence(one, two, 3);     three times two = 6

sentence(two, three, 14); 1 times three = 28

sentence(three, three, number + 1); 1 times 1 = 42

sentence(three, two, 1);   three times 1 = 2

sentence("eight", three, number / 2); 1 times eight = 20
