Answer:
Swapping two numbers means exchange the values of two variables with each other.
Answer:
Crosstalk, Jitter, Impulse noise.
Explanation:
Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.
Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes.
Impulse noise (also referred to as spikes) is the primary source of errors in data communications. Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.
Counter measures
Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.
Amplifiers can be used to increase signal strength since the connection would run across 4 floors.

Answer:disk caching
Explanation:
Disk caching speeds up hard drive performance
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.
