Answer: star topology.
Explanation:
The layout of the way how the computers in a netword are interconnected is called network tipology.
Some types of network topologies are:
1) Point-to-point tipology: all the computers are connected to each other directly (computer-to-computer, in pairs, this is a direct link between each two computers).
2) Bus topology: all the nodes (computers or server) are connectect to a maing cable.
3) Star topology: all the computers are connected to a central computer or server which is called central hub. This is the layout described in the question.
4) Ring topology: the computers are connectec in a circular path; each computer is connected to the next computer.
5) Mesh: every computer is connected to every other computer.
The technological tools that can be considered important for storing critical files are battery backup systems and drives. These devices can be used to store data and supply energy.
<h3>Battery backup systems</h3>
A home battery backup system is a device used to keep the electrical system working in the event when the electrical source goes down.
In computation, there are three major classes of batteries systems: Lead-Acid, Nickel-Cadmium, and Lithium-Ion.
An uninterruptible power supply (UPS) can be considered as a battery backup supply capable of charging when the power is on.

Answer:
//here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare an initialize first string variables
String st1="hello";
// declare an initialize first string variables
String st2="world";
// create another string variable
String st3;
// exchange the value of both string variables
st3=st1;
st1=st2;
st2=st3;
System.out.println("value of first String after exchange: "+st1);
System.out.println("value of second String after exchange: "+st2);
}catch(Exception ex){
return;}
}
}
Explanation:
declare and initialize two string variables.Create another string variable "st3". first assign value of "st1" to "st3" after then value of "st2" to "st1" and then assign value of "st3" to "st2". This will exchange the values of both the string.
Output:
value of first String after exchange: world
value of second String after exchange: hello
