Answer:
DUAL - HOMED FIREWALL
Explanation:
Dual-home firewall refer to an Ethernet device that has more than one network interface that sits between an untrusted network and trusted network in other to provide secure access.
In dua homed firewall one connection is an internal network and the second connection is to the Internet and works as firewall provided in which there is no direct IP traffic between the Internet and the internal network. In such a case, all Internet applications are run only on the dual-homed host.
Answer:
import java.util.Scanner;
public class num2 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int count =0;
int total = 0;
System.out.println("Enter the numbers");
int num = in.nextInt();
while(num!=-1){
total = total+num;
count++;
System.out.println("Enter the next number");
num = in.nextInt();
}
//Compute the average
double average = (double) total/count;
//Outputs
System.out.println("Total count of numbers entered "+(count));
System.out.println("Sum of the numbers "+total);
System.out.printf("Average is %.2f ",average);
}
}
Explanation:
- Using java programming language
- Import scanner class to receive user input
- declare variables count and total and initialize to zero
- Prompt user to enter numbers
- Use a while statement with the condition while(num!=-1)
- Within the while body keep prompting user to enter a number, increase count and update total
- when -1 is entered the loop breaks and average is calculated
- Use printf() method to print average to 2 decimal places.
